When limitations were in effect on nuclear-arms testing, people tended to save more of their money, but when nuclear arms testing increased people tended to spend more of their money. The perceived threat of nuclear catastrophe, therefore, decreases the willingness of people to postpone consumption for the sake of saving money.
The argument above assumes that
(A) the perceived threat of nuclear catastrophe has increased over the years
(B) most people supported the development of nuclear arms
(C) people’s perception of the threat of nuclear catastrophe depends on the amount of nuclear -arms testing being done
(D) the people who saved the most money when nuclear -arms testing was limited were the ones who supported such limitations
(E) there are more consumer goods available when nuclear-arms testing increases
On the basis of an observed correlation between arms testing and people’s tendency to save money, the argument concludes that there is a casual connection between a perception of threat and the tendency not to save. That connection cannot be made unless C, linking the perception of threat to the amount of testing being done, is assumed to be true. Therefore, C is the best answer.
The conclusion does not depend on there having been an increase in the perceived thread over time or on how many people supported the development of nuclear arms. Hence, neither A nor B is assumed. Furthermore, the argument does not deal with those who supported arms limitations or with the availability of consumer goods. Thus, D and E are not assumed.
Premise: When arms testing increases , people save less.
Conclusion: Perceived threat of nuclear catastrophe decreases people's willingness to save.
So Perceived threat of nuclear catastrophe also makes people save less.
That means "Perceived threat of nuclear catastrophe" also leads to the same result.
Why ?
Because "Perceived threat of nuclear catastrophe" depends on the "arms testing".
"Perceived threat of nuclear catastrophe" means "Arms testing".
They are proportional to each other.
So the assumption is :-
people’s perception of the threat of nuclear catastrophe
depends on the amount of nuclear -arms testing being done.
Option C is the correct answer.
