问题如下：
Q. Suppose the cost of producing tea relative to copper is lower in Tealand than in Copperland. With trade, the copper industry in Copperland would most likely:
选项：
A.expand.
B.contract.
C.remain stable.
解释：
A is correct. The copper industry in Copperland would benefit from trade. Because the cost of producing copper relative to producing tea is lower in Copperland than in Tealand, Copperland will export copper and the industry will expand.
题目不是说成本在T国比在C国低吗？那难道不是C国从T国进口，从而C国的industry在减少吗。感觉答案的解析说反了
