If the demand for our exports rises while our tastes for foreign goods falls off, then
(A) the value of the dollar will tend to appreciate
(B) the value of the dollar will tend to depreciate
(C) exchange rates will be affected but not the value of the dollar
(D) the exchange rate will not be affected
(E) the balance of trade will tend toward a surplus
答案是A，这个我同样能理解，可是E为什么有又不对呢？既然对美国出口的商品的需求上升，美国进口别国商品的欲望减小，那么export-import就会上升，使美国的balance of trade趋向surplus，有什么不对的吗？
