The supply schedule of pesos has a negative-sloping region corresponding to the inelastic region on the Mexican demand schedule for foreign currency.

这句话什么意思啊?无法理解.为什么是对的呢?

顺便也问一下这个:

The U.S. has a balance of trade deficit when its:

a. Merchandise exports exceed its merchandise imports

b. Merchandise imports exceed its merchandise exports

c. Goods and services exports exceed its goods and services imports

d. Goods and services imports exceed its goods and services exports

为什么答案是B而不是D呢?因为后面还做到了一道判断题:Concerning the balance of payments, the goods-and-services balance is commonly referred to as the “trade balance” by the news media.(答案是"T") 这么一来,两道题有矛盾了不是吗?
