Kim: In northern Europe during the eighteenth century a change of attitude occurred that found expression both in the adoption of less solemn and elaborate death rites by the population at large and in a more optimistic view of the human condition as articulated by philosophers. This change can be explained as the result of a dramatic increase in life expectancy that occurred in northern Europe early in the eighteenth century.
Lee: Your explanation seems unlikely, because it could not be correct unless the people of the time were aware that their life expectancy had increased.
Which one of the following, if true, provides the strongest defense of Kim’s explanation against Lee’s criticism?Kim says: life expectancy rose, and that caused a more optimistic outlook and less elaborate death rites. Lee objects: that only works if people knew life expectancy had increased.
(A) An increase in life expectancy in a population often gives rise to economic changes that, in turn, directly influence people’s attitudes.
Best defense. It shows a way Kim’s cause can work without people explicitly knowing life expectancy stats: longer lives can trigger economic and social changes that then shift attitudes.
(B) Present day psychologists have noted that people’s attitude toward life can change in response to information about their life expectancy.
This supports Lee more than Kim. It says attitudes change when people get information about life expectancy, which reinforces Lee’s “awareness” requirement.
(C) Philosophers in northern Europe during the eighteenth century made many conjectures that did not affect the ideas of the population at large.
Irrelevant to Lee’s point. It is about philosophers not influencing the public, not about whether life expectancy could affect attitudes without awareness.
(D) The concept of life expectancy is based on statistical theories that had not been developed in the eighteenth century.
This actually helps Lee. If the concept of life expectancy did not exist, people could not be aware of it in Lee’s sense.
(E) Before the eighteen century the attitudes of northern Europeans were more likely to be determined by religious teaching than by demographic phenomena.
Not a defense. It suggests religion used to drive attitudes, but it does not show that a demographic change could drive attitudes without awareness.
Answer: (A)
