**Analyzing the Meaning of "Text" in Context**

Okay, so the target word is "text," and it's being used in this discussion about climate talks. Hmm, let me think. The sentence is, "...said Stern, who also complained that the text did not do enough to make sure the cuts could be verified by outside observers." Right, the context strongly suggests this isn't the Bible, a textbook, or just the main body of a written work without illustrations. It's obviously referring to the *document itself* – the draft agreement, the negotiated language, the thing *written down*.

Let's look at these candidates. *Candidate 1*: "the words of something written." That seems spot on. Synonyms include "textual matter," and the example provided, "printed text of the mayor's speech," perfectly aligns with the idea of a draft climate agreement.

*Candidate 2*: No, Bible passage is out.

*Candidate 3*: Textbook? Nope, irrelevant here.

*Candidate 4*: Main body of a written work (vs illustrations)? No.

Okay, *Candidate 1*, "the words of something written," fits the bill perfectly. It's the language of the agreement. It's the text of the agreement. Bingo.

**Analyzing the Nuances of "Cuts" in Emission Reductions**

Okay, so the lemma is "cut," surface form "cuts," and the domain is greenhouse gas emissions – interesting. Let's see... the specific phrase is "binding cuts of greenhouse-gas emissions." Right away, I'm thinking about the implications. Based on that context I infer the problem: "the text did not do enough to make sure the cuts could be verified by outside observers." It's about ensuring these reductions are verifiable. My initial interpretation is reductions, that's the primary inference.

Now, let's confirm the sense. I've got a sense key: `cut%1:04:05::`. And the definition, "the act of reducing the amount or number," along with an example: "the mayor proposed extensive cuts in the city budget." That aligns perfectly with the emission context. The 'reduction' meaning is spot-on. Considering the verification aspect in the text, it reinforces that sense 19 is the best fit. I'm satisfied; the reduction sense is definitely the correct interpretation here.

**Analyzing the Semantic Sense of "Observer" in Context**

Okay, here's what I'm thinking. The target word is "observers" in the phrase "verified by outside observers." We've got two candidate senses from WordNet: sense 1, a perceiver, someone aware through the senses, and sense 2, an expert who observes and comments, a commentator.

My initial thought is that the context points towards sense 2. The phrase "outside observers" in international agreements usually refers to experts who independently monitor and verify. It's about an active role. I quickly check WordNet again and find those same two senses.

I'm pondering the specific action: "verifying cuts." These "outside observers" need to be actively engaged in inspecting and evaluating, making them experts. They're not just passive perceivers. But then I have to consider if "commenting" is quite right - a commentator is usually someone who *expresses opinions* in a public forum, right?

I start thinking about "monitor" as a potential synonym but WordNet doesn't list it. But a monitor is *looking at* the cuts, so maybe that's where I go. I try and think about "outside observer" in a general sense, and it might map to sense 1 more because it's about someone who is looking at something, but in this specific context I realize it isn't necessarily just looking.

I'm considering whether these observers in this specific case are really commentators in the punditry sense. They're definitely *reporting* and maybe *assessing*, but "commentator" implies public opinion. I think about elections, UN observers – Are they "commentators" or people sent to check and report? They are, by definition, observing.

This is where I get a bit of a wrinkle. I have to make a choice between perceiving (sense 1) and commenting (sense 2). But in the phrase "verified by outside observers", they are certainly doing more than just casually observing. But this has to be a real-world analysis, and a "perceiver" is much more general (almost a default). They *see* the cuts and *verify* them.

Then, I'm thinking about outside observers in contexts such as elections. They are not commentators but are there to ensure fairness, which is what is happening here with greenhouse gases. That strengthens my thought for sense 1, a "person who becomes aware through the senses." The verb here is verified. I need to select the word that describes a physical act, not necessarily a pundit's role.

I'm thinking about "expert who observes and comments," and "comment" feels a bit off for what they're doing. "Observer" here is used because they don't have the power to enforce, they just observe and verify. I consider SemCor, but I'll have to choose between the two candidate senses. I double-check the definition of sense 2 (an expert who observes and comments) and think "are these *commentators*?" Well, not necessarily.

Ultimately, between a general "perceiver" and an "expert who comments," I keep leaning towards sense 1. They may be experts, but the focus is on their role as external inspectors, not as pundits.

**Analyzing the "Comments" Context**

Okay, so the word I need to understand is "comments," and the text has it in the plural form. Let me see... here's the context: "Stern made his comments an hour after Chinese vice foreign minister He Yafei said America's top climate negotiator was either lacking 'common sense' or being 'extremely irresponsible'..." Right, I need to figure out which sense of "comment" is intended here.

First, I'm going to look at the candidate senses. I see three possibilities. Number one is "a statement that expresses a personal opinion or belief or adds information" – that sounds like a "remark" or "input." Sense two is "a written explanation or criticism or illustration that is added to a book or other textual material," which is a "commentary." And number three is "a report (often malicious) about the behavior of other people" – essentially, "gossip."

Now, focusing back on Stern. His statements were about America's position ("The United States is not going to do a deal..."). They were essentially his stated opinion, a position. Considering this, Sense 1 makes the most sense. Sense 2 is clearly incorrect, as his remarks are not written additions to a text. Sense 3, "gossip," doesn't fit the context at all; his remarks are not rumors about the negotiators' behavior.

Therefore, the best fit is Sense 1. The word "comments" in this context refers to his remarks expressing the administration's stance.

**Analyzing the "Hour" Context**

Okay, so the target is "hour," and the surface form is, well, "hour." Straightforward enough. The context provided is: "Stern made his comments an hour after Chinese vice foreign minister He Yafei said America's top climate negotiator was either lacking 'common sense'..." My initial impression is that "hour" is likely referring to a duration of time.

Let's examine the candidate senses. I'm seeing:

1.  A period of 1/24th of a day, or 60 minutes. That feels right, given the context of "an hour after."
2.  Clock time. No, the context isn't about the specific time.
3.  A "special and memorable period." Doesn't fit here at all.
4.  Distance measured by time – "we live an hour from the airport." While related to time, it's about distance, not elapsed duration.

Considering that the phrase is "an hour *after*," it's clearly a measure of elapsed time. That absolutely aligns with sense 1: the period of time, 60 minutes. Therefore, I can confidently select that sense as the correct interpretation of "hour" in this sentence.

Okay, so the target word is "america," and it's presented as "America" in this text. Let's dig in. The context here is a political jab about climate negotiations. The sentence explicitly mentions "America's top climate negotiator," which immediately points me toward the U.S. envoy, Todd Stern. With that clarification, it's clear we're dealing with the geopolitical entity, not the whole American continent.

Looking at the sense candidates, sense 1 is the slam dunk, defining "america" as the "North American republic containing 50 states... United States, United States of America, the States, US, USA." Sense 2, referring to the entire Americas, is completely irrelevant in this context. It's a clear case of semantic disambiguation. So, sense 1 it is. I'm confident in assigning that meaning.

**Analyzing the Term "Climate" in Context**

Okay, so the key word here is "climate." My immediate thought process is to consider the potential ambiguities – we're dealing with language, and even in technical fields, multiple meanings can surface. The context is "Chinese vice foreign minister He Yafei said America's top climate negotiator was either lacking..." Immediately, I recognize this is about something political.

The text mentions "climate change" and "global warming," which are dead giveaways. I know this phrase relates to the environmental climate, the long-term weather patterns and averages. Now, I have to mentally disambiguate. Does "climate" refer to the meteorological sense – the standard "clime" definition – or a more abstract sense? I know the word "climate" can also mean the "prevailing psychological state" or mood.

Given that it's a "climate negotiator" being discussed, the relevant area is definitely environmental. Therefore, the first sense, the meteorological one, is clearly the intended meaning here.

Okay, so the target word is "week" in the context of a statement made "earlier in the week." Given my expertise, I immediately recognize that "week" can have multiple senses. I need to pinpoint the intended one here, as it's crucial for accurate interpretation of the text.

The phrase "earlier in the week" is a key indicator. It suggests a specific, named entity of time. I'm immediately thinking calendar week. Let's see... I'm going to quickly check the options to confirm my first impression:

*   **Sense 1:** "any period of seven consecutive days" – while accurate, it lacks the specificity implied by "earlier in the week." Think, "it rained for a week." Not relevant here.
*   **Sense 2:** "hours or days of work in a calendar week" – clearly incorrect in this context. We're not talking about a work schedule.
*   **Sense 3:** "a period of seven consecutive days starting on Sunday" - Yes! This seems the strongest contender.

The phrase "earlier in the week" points to the calendar week (sense 3), which is specific to that particular time. Is it referring to this calendar week or a generic week? I am confident in my initial assessment that it refers to the calendar week. In cases of doubt, however, I prefer to check wordnet. Yes, the reference in this phrase is to the *specific* calendar week. Therefore, my initial assessment stands.

I am confident, therefore, that sense 3 is the intended meaning, representing the calendar week in which the talks on Friday took place. This is the correct sense.

Target lemma: united_states
Target surface form: United States
Context:
The European Union gave the talks a boost as well on Friday by pledging to provide $3.6 billion a year over the next three years to help poorer countries adapt to the impact of climate change -- from coping with flood and drought to avoiding deforestation. Still, Friday featured the same sort of verbal fireworks that have dominated the talks for the past week. U.S. special climate envoy Todd Stern rejected language requiring binding cuts of greenhouse-gas emissions for industrialized countries compared with voluntary ones by major emerging economies if they were not funded by the developed world. The move signaled that the Obama administration is taking a harder line with China than Bush administration officials did just two years ago. The United States is not going to do a deal without the major developing countries stepping up and taking action, said Stern, who also complained that the text did not do enough to make sure the cuts could be verified by outside observers. Stern made his comments an hour after Chinese vice foreign minister He Yafei said America's top climate negotiator was either lacking "common sense" or being "extremely irresponsible" for saying earlier in the week that the <t>United States</t> would not help China financially to cope with global warming. With the future economic trajectory of the world's major powers at stake, fault lines have erupted both within the developing world and between the industrial world and emerging economies.

**My Analysis of "United States" in Context**

Okay, so the target is "united_states" and the surface form is "United States." My task is to determine the correct sense in this particular sentence: "the United States would not help China financially..." The candidate senses are the country itself (Sense 1) and the US government (Sense 2).

Initially, my instinct is that when we're talking about international relations, "United States" usually defaults to the nation-state, the country, the republic—Sense 1. I'm thinking about the action of *helping financially*, which is something a nation does. I start by considering if the distinction matters. In this sentence, the action of helping financially points to a political/governmental action. "The United States government" and "the United States of America".

Now, I'm reminding myself that "United States" can refer to Sense 2, the government, but that this usage is more common when differentiating the federal government from state governments. The phrase "the United States" acting internationally usually refers to the country as a whole, the nation, as it does when contrasting it with "China" and "developing countries" or "the developed world." For instance, in a sentence like "The United States is not going to do a deal...". It seems as though I'm thinking of "China" as the country here, and not its government. I need to make the same determination for the US.

I'm checking if the sentence could refer to the US government and considering "the United States government, U.S. government, U.S." vs. "United States of America, America, the States, US, USA". "United States" without "government" implies the geopolitical entity.

Therefore, given the context of international relations, and the lack of explicit reference to the government machinery, my final conclusion is that Sense 1—the country, the republic—is the correct interpretation.

**Analyzing the Context of "China"**

Alright, let's break this down. The target is "china," but it's presented as "China," so we're dealing with a proper noun here. The context is climate change negotiations, with mentions of the US, Todd Stern, He Yafei, and financial aid regarding global warming. My expert brain immediately starts sifting through the possible senses.

*   **Sense 1:** The People's Republic of China, the massive nation in East Asia. This is the obvious first contender.
*   **Sense 2:** High-quality porcelain. A classic, but unlikely given the context of talks and international relations.
*   **Sense 3:** The government on Taiwan, the Republic of China. Possible, but less likely than the mainland.
*   **Sense 4:** Dishware made of porcelain. Definitely off the mark.

Given that we have a Chinese Vice Foreign Minister, He Yafei, involved in talks, the first sense – the People's Republic of China – is a slam dunk. No question about it. It's the only one that meaningfully fits this discussion of climate change and international negotiations. Therefore, sense 1 is the clear winner.

**Analyzing the Meaning of "World"**

Okay, the target lemma is "world" and the surface form is also "world". The context is "With the future economic trajectory of the world's major powers at stake...". My initial thought is that "world" here refers to the planet, the Earth, possibly the international community. "The world's major powers" – that suggests the countries or nations *on* the globe, doesn't it? Let's look at the candidates.

I'm checking Sense 4: "the 3rd planet from the sun; the planet we live on" with synonyms "Earth, globe." Sense 1 ("everything that exists anywhere | universe") and Sense 8 ("all of the living human inhabitants of the earth | human race") don't seem like the best fits right away.

The phrasing "the world's major powers" strongly implies countries on Earth, so the "Earth/globe" sense feels natural. Let's see... a similar phrase "the world's two dozen most influential countries" – again, that implies the countries on the planet. I recall WordNet's sense "world%1:17:00::" with "Earth, globe" as synonyms, and examples like "he sailed around the world" and "the Earth moves around the sun" which seem quite fitting. This "globe/Earth" sense *logically* encompasses political entities located on the planet, such as major powers.

Let's quickly scan the other senses just to be thorough. Sense 2 (people in general; distinctive group...), Sense 5 (people in general considered as a whole), and Sense 8 (all of the living human inhabitants of the earth) - they don't seem as precise.

Yes, in "the world's major powers," "world" is referring to the globe, the Earth, the planet. It's like saying "world map" or "world powers." Sense 4, without a doubt, appears to be the most appropriate.

Just to confirm, I'll replace "world" with one of its synonyms to test it. "the future economic trajectory of the globe's major powers". That fits perfectly. "Earth's major powers" also works.

So, let's look at it one last time. Sense 4: "the 3rd planet from the sun; the planet we live on," with the example "he sailed around the world". Yes, the "world" here indisputably refers to the Earth.

**Analyzing the Nuances of "Battle" in a Global Context**

Okay, so the target word is "battle" and it's used in this sentence about climate change negotiations between the US and China. My initial instinct is to go beyond the literal. "Hostile meeting of opposing military forces in the course of a war" – no, that's definitely not it. The context is diplomatic, a clash of interests, not actual warfare.

The second candidate, "an energetic attempt to achieve something," is interesting. It implies a struggle, which is relevant. A "battle for recognition," perhaps? But it doesn't quite capture the antagonistic element I'm sensing here.

Now, the third candidate, "an open clash between two opposing groups (or individuals)," that's hitting the mark. The context mentions "China and United States feuding," "fault lines have erupted," and "fighting over who should bear the costs." All of those phrases suggest a very public, very direct conflict. It’s a diplomatic struggle, a disagreement played out on the global stage, a “battle” of wills and policy. That sense of open disagreement is key. It's a "conflict", a "struggle".

So, the "battle" here is a diplomatic one, a clash between nations, not a military one. That third definition is definitely the best fit. I'm going with sense index 3.

**Analyzing the Meaning of "Economies"**

Okay, so the prompt is focusing on "economies" within the phrase "saving individual economies as saving the planet." Immediately, my mind jumps to the context: the U.S., China, developing countries, industrialized nations – the whole economic spectrum. This has to be about national economic systems, not just any old economy.

Let's break down the senses and make sure.

1.  *Economy%1:14:00:: - the system of production, distribution, and consumption*. This seems like the obvious fit. We're talking about the overall economic structure of a country – that's a *system*.
2.  *Economy%1:09:01:: - the efficient use of resources*. While relevant to national economies, it's not the *core* meaning here.
3.  *Economy%1:07:00:: - frugality in spending*. This is related to *being* economical, but again, not the primary intent.
4.  *Economy%1:04:00:: - an act of economizing; saving*. Like sense 2, this is related but it's not the underlying system being discussed.

Sense 1 is the clear winner. "Individual economies" in this context refers to the economic systems of countries like the U.S. or China, essentially their whole economic trajectories. I'm satisfied; the meaning is the *national economic system*.

I've got a few senses to consider: china%1:15:00:: (a communist nation that covers a vast territory in eastern Asia), china%1:06:00:: (high quality porcelain), china%1:15:01:: (a government on the island of Taiwan), and china%1:06:01:: (dishware made of high quality porcelain). Considering the geopolitical nature of the sentence, sense 1 is the clear winner. The other three senses are completely irrelevant to the discourse. The first sense encapsulates the correct understanding of "China" in this context.

**Analyzing the Context of "United States"**

Okay, so the task is to disambiguate "United States" in this sentence: "The current battle is as much about saving individual economies as saving the planet, with China and United States feuding over their respective obligations while poorer nations insist..." The target surface form is "United States," and the lemma is "united_states." My first instinct is to consider the two main senses in WordNet: the country (sense 1) and the government (sense 2).

Given the context of international relations, specifically the phrase "China and United States feuding," it seems highly likely it's referring to either the nation-state or the government as an actor. I need to figure out which. I'll quickly check the WordNet glosses for both senses. Sense 1 is the "North American republic containing 50 states," which includes synonyms like "America." Sense 2 refers to the "executive and legislative and judicial branches of the federal government."

In this scenario, I'm leaning towards the country sense. The key here is the parallelism with "China," and the overall phrasing, "individual economies." China likely isn't used to refer to its government. Also, consider the phrasing in the context, "...while poorer nations insist." I'm reading "United States" and "China" as being in parallel to each other and also parallel with "poorer nations." Those are all countries, so, that strongly implies sense 1, the country.

Now, double-checking sense 2, that's the *government*. In the context of international relations, "United States" acts *as* a country or nation. Considering the synonym "America" in sense 1 is also relevant, especially since it earlier mentions "America's top climate negotiator." I'm confident that sense 1 is the correct choice here.

**Analyzing the Meaning of "Obligations" in Context**

Okay, the target is "obligations," the surface form "obligations," and the context involves China and the US. The phrase "feuding over their respective obligations" is key. My initial thought is that it refers to their responsibilities or duties regarding emission cuts and funding for global warming solutions.

Let's quickly run through the possible senses. We've got:

1.  "The social force that binds you... duty, responsibility"
2.  "The state of being obligated to do or pay something"
3.  "A personal relation in which one is indebted..."
4.  "A written promise to repay a debt"
5.  "A legal agreement..."

Sense 1 and 2 seem the most relevant initially. The others don't fit the context directly. "Obligations" here is about what they *should* be doing, not a specific agreement or debt. Is it Sense 1 or Sense 2? It appears to be a count noun; their respective *duties*. Thinking through, with Sense 1, we see "every right implies a responsibility; every opportunity, an obligation," which sounds similar to the context, and it's also a count noun. Sense 5 would involve a legal contract and is not fitting. Therefore, Sense 1, which represents "duty, responsibility," seems the best fit. I'm going with Sense 1.

**Analyzing the Usage of "Nations"**

Okay, so the lemma is "nation", and the surface form is "nations." The context is: "...while poorer nations insist that the world's two dozen most influential countries are ignoring the scientific imperative to take bolder action." Right off the bat, I need to narrow down the sense. Let's see...

I've got a few candidate senses here: a politically organized body under a government (that's the classic "state" or "country" sense), the people themselves living within that nation, a historical reference, and a federation of tribes. Given the context, it's pretty clear that "poorer nations" is referring to these nations as *actors* in the global political arena, like "countries" or "economies". They're *insisting* on something, so they're operating on that diplomatic stage.

Now, looking at those senses again: sense 1, the political entity, lines up with things like "African nations," representing a specific, govern-ed territory and body of people. Sense 2 focuses on the people within that entity - how they *feel* or are *addressed*. This is where "the nation's mood" or "announcement to the nation" comes in. The context here strongly suggests that the nations are functioning as political entities with delegates, able to make demands. "poorer nations" correlates directly with "countries" in this context.

So, the first sense looks like the best fit, but let's verify. Let's make an analogy.

Sense 1: "African nations" -> "poorer nations".
Sense 2: "the nation's mood", "announced to the nation".

The "poorer nations" fit very well with the first example, in which the term is used as a political entity. So, yes, definitely Sense 1. This is straightforward.

**Deconstructing "World" in Context**

Okay, the target word is "world" within the phrase "the world's two dozen most influential countries." Let's break down the potential senses. I've got a list here: universe, the Western world (a group), reality (my experience), the Earth, the populace, a specific outdoor setting, worldly concerns, and humanity.

My initial thought is that it's referring to the countries *on* the planet Earth. So, that feels like Sense 4: Earth, the globe. "Countries *of* the world" implies countries on Earth, geographically. "He sailed around the world" — fits, I think. Earth, globe. Perfect.

Let's quickly check if there are any gotchas. We'll cross-reference Sense 4 with Sense 1 (universe) and Sense 8 (humanity) just to make sure. Okay, "the world's major powers"...still referring to powers *of* the world, the globe, the Earth. Definitely Sense 4.

Wait, could it possibly be humanity? No, countries are political and geographical, located on Earth. No, Sense 4. "The globe's most influential countries." Yes, it's definitely Sense 4: Earth, the globe. We're good.

**Analyzing the Lemma "Countries" in Context**

Okay, here's how I'm breaking this down. The target lemma is "country," specifically the plural "countries," and the context is about "the world's two dozen most influential countries." My immediate thought is, this is likely a political usage, but let's make sure. I've got five potential senses mapped out: a political entity (sense 1), territory (sense 2), the people (sense 3), a rural area (sense 4), and a vaguely defined region (sense 5).

Given the phrase "most influential countries" and the surrounding text about action (or lack thereof) on the global stage, I'm leaning heavily towards sense 1 – the politically organized entity, the nation-state. This context screams of countries as actors, governments making decisions. The reference to "ignoring the scientific imperative" implies actions taken (or not taken) by the governing bodies themselves.

To solidify this, I'm checking the synonyms for sense 1: "state," "nation," "land," "commonwealth," "res publica," "body politic." All of these perfectly align with the idea of these "influential countries" holding power and making decisions. I'm also confirming with an example, like "African nations," which is clearly about the political entity.

Sense 2, the physical territory, doesn't quite fit. It would be something like, "he travelled to several countries". Sense 3, the people, isn't a direct match either: "the news was announced to the nation."

Based on the surrounding context, I'm confident that sense 1 is the correct one. The phrase "the world's two dozen most influential countries *are ignoring...*" makes it clear that we're talking about governments, not the physical land or the population. The term "influential countries" solidifies this interpretation. Therefore, I can confidently identify sense 1 as the correct definition.

**Analyzing the Meaning of "Imperative"**

Okay, so the task is to pinpoint the specific meaning of "imperative" within the sentence, "...ignoring the scientific imperative to take bolder action." Let's break this down. First, I need to consider the potential senses of the word. From my understanding, "imperative" can refer to a grammatical mood, like the imperative mood in language, used to issue commands or suggestions. But, in this context, that feels immediately wrong. The alternative, and what I believe is the most likely, is that "imperative" represents some sort of essential and urgent duty, a pressing obligation.

Considering the surrounding context is key. We are talking about climate change and the need for action. Given this, "scientific imperative" clearly means an essential and urgent duty stemming from scientific findings and evidence. The "imperative" isn't a grammatical device; it's a call to action rooted in scientific understanding. Therefore, the second sense is definitely the more accurate interpretation here.

**My Analysis of "Costs" in Context**

Okay, here's how I'm thinking through this. The target is "costs," specifically the plural "costs" as it appears in the phrase "bear the costs for curbing greenhouse gases." The context immediately suggests a financial or economic burden, given the surrounding phrases about "financially to cope with global warming," "economic trajectory," and "economic hegemony." So, I need to pick the best sense from the candidates provided.

My initial thought is that sense 1, "the total spent for goods or services including money and time and labor," seems like the most promising fit. When someone says "bear the costs," especially in a plural form, it usually implies a financial expenditure. It's about paying, the financial burden.

Then, I'm second-guessing a bit and going over sense 3, "value measured by what must be given or done or undergone to obtain something" because it's broader (price, toll). It feels a little metaphorical, like "the cost in human life" or "the price of success is hard work" – I'm just not sure it matches how *costs* is used here, because it leans more on a non-monetary value.

The real question is whether "curbing greenhouse gases" is a "good or service" under the definition in sense 1. It's an action, and I *could* argue that it represents an economic program or initiative. However, the context is all about financial obligations. If we are using the cost of money/time/labor to undertake a particular initiative, like curbing greenhouse gases, this strongly aligns with sense 1.

I'm now zeroing in on sense 1. My understanding is that the expression "bear the cost" typically aligns with it. In cases like this, "costs" usually refer to financial expenses or total financial expenditure. I re-read sense 1 again to confirm that.

Alright, let's look at sense 1 from WordNet: "the total spent for goods or services including money and time and labor." That's the one.
It's a slight stretch to see "curbing greenhouse gases" as a "good or service," but I know that in economics, costs are generally viewed through the lens of sense 1. Given the surrounding text mentioning finances and economics, I'm confident that sense 1 is the best interpretation in this case.
Therefore, sense 1 is my choice.
