Key Trap: The conclusion equates having the same borders today as 20 years ago with having stable borders throughout the last 20 years. Choice (A) breaks that equivalence by showing the borders may have changed during the period and simply ended up back where they started.

A. Correct : The conclusion treats unchanged borders as evidence of stability. However, if Senovia's borders were changed and then restored to their original shape just last year, it did not actually enjoy continuous border stability over the past 20 years. This directly undermines the conclusion.

B. Incorrect: This strengthens the argument by showing that neighboring countries experienced significant border changes, making Senovia appear comparatively more stable.

C. Incorrect: This provides background about the region but does not show that Senovia itself was unstable.

D. Incorrect: The conclusion refers specifically to stability of borders, not economic stability. This is outside the scope of the argument.

E. Incorrect: If border disputes have become less likely in the region, this is consistent with the idea that Senovia is stable and does not weaken the conclusion.

Premise: Of the 4 countries in the Senovian Mountain region, Senovia is the only one to have the same borders today as it did 20 years ago.

Conclusion: ­Senovia can be looked upon as an example of stability within an unstable region.

Which of the following if true, would most weaken the conclusion presented above?

A. After years of dispute between Senovia and its neighbors, the United Nation redrew the country’s borders to match their original shape last year.
Correct: Now it’s stable as it’s the only one having the same borders today as it did 20 years ago. But has it been stable throughout all these years? It might be the case that it got into a peaceful period after going through several rough patches.

B. Two of Senovia’s neighbors split from one another to create independent countries 10 years ago.
Wrong: we’re not concerned with Senovia’s neighbors.

C. Many countries in the region are more interested in acquiring new territory than they are in stabilizing existing borders.
Wrong: this statement would confirm that many countries are unstable, (unlike Senovia or including Senovia?). In any case, the focus in not explictly Senovia, so we don’t know if this city is included. It may or it may not be.

D. Senovia has had unsteady economic growth during the 20 years in question.
Wrong: we’re talking about stability because of borders, not economy. This is frameshift.

E. As more countries in the Senovian Mountain region have joined global alliances, border disputes have become less likely.
Wrong: so this would explain that Senovia is stable, but we need to prove the opposite.

VERITAS PREP OFFICIAL EXPLANATION:



For any weaken question, remember that your first step is always to fully understand the stimulus and to find the gap. This question makes a generalization: it says that because the country of Senovia is the only one in the region to have the same borders as it has 20 years ago, that it can be considered a stable force in an unstable region. However, you only have two snapshots in time: the borders of Senovia as they are now and the borders of Senovia as they were 20 years ago. You don't have any other points of reference within that 20-year period.

Choice (A) perfectly fills this gap. Even though the borders are the same as they were 20 years ago, not only have they shifted over the last 20 years, but the instability was severe enough that the United Nations had to intervene.

Among the other answers, choice (B) strengthens the assertion that the rest of the region is relatively unstable. Choice (C) can be eliminated because it has to do with the intentions of other countries rather than the stability of Senovia itself. Choice (D) can be eliminated because the argument is about the stability of Senovia rather than its economic growth, and choice (E) can be eliminated because it is a general statement about the region as a whole rather than the stability of Senovia itself.­

I have a question that if borders were redrawn then it would be for all the 4 countries, but why is Senovia the only country for which borders are same as 20 yrs ago, it would be for all 4 countries ?

I’d say the issue is that (A) does not say all four countries’ borders were restored to their original shapes. It says Senovia’s borders were redrawn to match their original shape.

That can happen even if neighboring countries still have different borders today because of other disputes, splits, or territorial changes.

So Senovia can still be the only country with the same borders today as 20 years ago, but (A) weakens the argument because those borders were not stable throughout the period.

Hi namanqqkm,

Good question, and the fix is right there in the exact words of choice A. Look at what it says gets redrawn:

"the United Nation redrew the country's borders to match their original shape last year."

"The country" here means Senovia only - not all four countries. The choice is describing a change made to Senovia's borders specifically, restoring them to the shape they had before. It never says the UN redrew everyone's borders across the region.

So your reading - that a redrawing would apply to all 4 - isn't what A states. If it had said the UN reset the whole region's borders, then yes, your objection would land. But A is deliberately narrow: it targets Senovia alone.

Why that wording is exactly what weakens the argument

The conclusion says Senovia is "an example of stability" using only two snapshots: its borders today and its borders 20 years ago. Since those two match, the author assumes nothing happened in between.

Choice A fills that blind spot for Senovia specifically:

- Senovia had "years of dispute" with its neighbors.
- Its borders actually shifted during the 20 years.
- They only match the original shape because the UN restored them last year.

Therefore, the "same borders today" is the result of a recent fix, not of continuous stability. That's the whole weakener - and it works because the change is about Senovia, the one country the conclusion is about. If A were about all four countries equally, it would say nothing special about whether Senovia was stable.

Bottom line: read "the country's borders" as "Senovia's borders," and A snaps into place.

Answer: A
