21. 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 C
E. there are more consumer goods available when nuclear-arms testing increases
此题算不算是因果型结论，如果算，用lawyer的那种方法解，如果不算，什么样的算是因果型结论？多谢
这道题是标准的前提结论结构，即通过一个前提，推出一个结论，像therefore,thus,conclude都是明显的标志词。
因果结构结论是前提的原因，即对某种现象或矛盾提出一种解释，改解释就是结论。
文章中标志词due to, attribute to , result of ,responsible for..., 问题中标志词explanation, interpretation, hypothesis
