A physically active lifestyle has been shown to help increase longevity. In the Wistar region of Bellaria, the average age at death is considerably higher than in any other part of the country. Wistar is the only mountainous part of Bellaria. A mountainous terrain makes even such basic activities as walking relatively strenuous; it essentially imposes a physically active lifestyle on people. Clearly, this circumstance explains the long lives of people in Wistar.

Which of the following, if true, most seriously weakens the argument?

(A) In Bellaria all medical expenses are paid by the government, so that personal income does not affect the quality of health care a person receives.

(B) People living in Wistar do not have a significantly better diet than people living in other parts of Bellaria.

(C) Many people who live in the Wistar region have moved there in middle age or upon retirement.

(D) The many opportunities for hiking, skiing, and other outdoor activities that Wistar's mountains offer make it a favorite destination for vacationing Bellarians.

(E) Per capita spending on recreational activities is no higher in Wistar than it is in other regions of Bellaria.

A physically active lifestyle has been shown to help increase longevity. In the Wistar region of Bellaria, the average age at death is considerably higher than in any other part of the country. Wistar is the only mountainous part of Bellaria. A mountainous terrain makes even such basic activities as walking relatively strenuous; it essentially imposes a physically active lifestyle on people. Clearly, this circumstance explains the long lives of people in Wistar.

Which of the following, if true, most seriously weakens the argument?

(A) In Bellaria all medical expenses are paid by the government, so that personal income does not affect the quality of health care a person receives. -If people in entire country don't have to bear the medical expenses then this option removes an alternate cause regarding the longevity of people. STRENGTHENER

(B) People living in Wistar do not have a significantly better diet than people living in other parts of Bellaria. -If the diets are not common, this option removes an alternate cause regarding the longevity of people. STRENGTHENER

(C) Many people who live in the Wistar region have moved there in middle age or upon retirement. -Correct. This shows that the average of people living in Wistar is already higher than that of rest of the people in country.

(D) The many opportunities for hiking, skiing, and other outdoor activities that Wistar's mountains offer make it a favorite destination for vacationing Bellarians. -Out of scope

(E) Per capita spending on recreational activities is no higher in Wistar than it is in other regions of Bellaria. -If there is no difference between the spending on activities then this option removes an alternate cause regarding the longevity of people. STRENGTHENER

The correct answer here should be C. Here is the reason why:

Situation: Due to mountainous region in the Wistar region, people have much physical activity, even walking is strenuous there. Hence the average age at death is higher than other age at other regions in Bellaria.

Reasoning: Which information would weaken the argument. Any information that challenges this conclusion will weaken the argument. It is assumed the people who have moved to wistar region of bellaria already are middle or in old age would weaken the reasoning given for much physical activity in wistar region.

We are told that the lucky people of Wistar live considerably longer, on average, than people in other parts of Bellaria. The author concludes that the long lives of the Wistarians can be explained by the fact that their mountainous environment "essentially imposes a physically active lifestyle on people." To review the author's argument:

  • A physically active lifestyle has been shown to help increase longevity (i.e. to help people live longer).
  • The average age at death of people in Wistar is considerably higher than the average age at death of the people living elsewhere in the country. In other words, Wistarians seem to live longer than other Bellarians.
  • Wistar is the only mountainous part of Bellaria, and the mountainous terrain makes even such basic activities as walking relatively strenuous.
  • Because of the mountainous terrain, Wistarians are essentially forced to live physically active lifestyles (even something as basic as walking around is a physically demanding activity in Wistar). Since a physically active lifestyle has been shown to help increase longevity, it follows that the mountainous terrain would naturally increase longevity among the Wistarians.

But can we safely conclude that the mountainous terrain is what explains the long lives of the Wistarians? We need to find the answer choice that most seriously weakens the author's argument:

Quote:
(A) In Bellaria all medical expenses are paid by the government, so that personal income does not affect the quality of health care a person receives.

What if personal income is higher in Wistar and, as a result, the people of Wistar have better healthcare? That could explain the long lives of the Wistarians and thus weaken the argument. However, choice (A) tell us that personal income does NOT affect the quality of health care. Choice (A) gives us no reason to suspect that Wistar has better healthcare, so (A) can be eliminated.

Quote:
(B) People living in Wistar do not have a significantly better diet than people living in other parts of Bellaria.

If people in Wistar HAD a significantly better diet than people living in other parts of Bellaria, then that might explain why the Wistarians live longer. However, choice (B) tells us that this is not the case and thus removes a possibility that would weaken the argument. Choice (B) does not weaken the argument and can be eliminated.

Quote:
(C) Many people who live in the Wistar region have moved there in middle age or upon retirement.

The author's idea is that Wistarians enjoy longer lives because they are essentially forced to lead active lifestyles. But what if many of the people living in Wistar didn't move there until middle age or upon retirement? In that case, those people, upon moving to Wistar, would be no different (physically) than the people living elsewhere in the country. Sure, now that they live in Wistar, they are essentially forced to lead a more active lifestyle, but would that explain the considerable difference in the average age of death? The author's argument and conclusion could still be true, but choice (C) definitely weakens the argument by suggesting that many Wistar residents have not lived there long enough to be significantly affected by their environment. Hang on to this one.

Quote:
(D) The many opportunities for hiking, skiing, and other outdoor activities that Wistar's mountains offer make it a favorite destination for vacationing Bellarians.

The argument and conclusion pertain to the people who LIVE in Wistar. We are not concerned with tourists or vacationers, so (D) can be eliminated.

Quote:
(E) Per capita spending on recreational activities is no higher in Wistar than it is in other regions of Bellaria.

If recreational activities were significantly CHEAPER in Wistar, that might explain why the Wistarians are more active and why they live longer. But choice (E) tells us that this is not the case. The author's point is that just LIVING in Wistar is enough to affect longevity. Choice (E) does not impact this argument and even eliminates a scenario that would weaken the argument. Thus, (E) can be eliminated.

Choice (C) is the best answer.

The way I look at this question - the avg age at death is higher in Bellaria. Reason given - People in Bellaria live a more physically active lifestyle, leading to a longer life span. Option A provides us with an alternate reason in that the government pays for the medical expenses of all people. This can thus be the reason for the high life expectancy of the people in Belleria, contributing to weaken the explanation given that attributes this high life expectancy to the physical lifestyle. Can someone explain me the flaw in my reasoning

abhigulia3006, we are not trying to explain why ALL people in Bellaria live long lives. We need to explain why the average age at death is considerably higher in Wistar.

Choice (A) describes a benefit to ALL residents of Bellaria. Sure, having all medical expenses paid by the government might increase your life expectancy, but why do the people in Wistar live considerably longer lives than other people in Bellaria?

According to (A), Wistarians receive the same government benefits as all other Bellarians, so there is no reason to suspect that they will live longer. If choice (A) said that the government ONLY pays the medical expenses for Wistarians, then it would weaken the argument. As is, (A) is not a weakener because it does not differentiate between Wistarians and other Bellarians.

I hope that helps!
