Curbing government spending has been demonstrated to raise the value of a
country's currency over time. However, many economists no longer recommend
this policy. A currency of lesser value causes a country's exports to be more competitive
in the international market, encouraging domestic industries and making
the economy more attractive to foreign investment.
The statements above most strongly support which of the following inferences?
(A) Limited government spending can also lead to a reduction in the national
deficit.
(B) Curbing government spending can make a country's exports less competitive.
(C) Many economists now recommend higher levels of government spending.
(D) An increase in the value of a currency will result in reduced government
spending.
(E) Competitive exports indicate a weak currency
我来写一下逻辑链哈
1.curb spending 推 currency value rise
2.currency of lesser value 推 more competitive exports
这是两个原命题，原命题呢又和逆否命题是等价的。而B选项中，逻辑链是 curb spending 推currency value rise 推 less competitive exports。 这不是明显的2的否命题吗？？？原命题和否命题并不等价啊！！
currency value下降有出口更加competitive，并不能推出currency value上升 有出口less competitive啊！！！
