13. Canadians now increasingly engage in “out-shopping,” which is shopping across the national border, where prices are lower. Prices are lower outside of Canada in large part because the goods-and-services tax that pays for Canadian social services is not applied.
Which one of the following is best supported on the basis of the information above?
(A) If the upward trend in out-shopping continues at a significant level and the amounts paid by the government for Canadian social services are maintained, the Canadian goods-and-services tax will be assessed at a higher rate.
(B) If Canada imposes a substantial tariff on the goods bought across the border, a reciprocal tariff on cross-border shopping in the other direction will be imposed, thereby harming Canadian businesses.
(C) The amounts the Canadian government pays out to those who provide social services to Canadians are increasing.
(D) The same brands of goods are available to Canadian shoppers across the border as are available in Canada.
(E) Out-shopping purchases are subject to Canadian taxes when the purchaser crosses the border to bring them into Canada.

答案是 A      此题已经讨论过  但是我依然不能理解    为什么  政府对社会服务的支出不变   去国外买东西的趋势增加  就会导致 物品服务税的增加   难道是 因为更多的人去国外买东西  政府收税少了 因此 为了维持对社会服务的总支出不变  就要提高税率  相当于  a=b*c  a 不变  b下降 c就一定要上升  么？
