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.
"铜地"的铜工业将从贸易中受益。由于铜的生产成本比茶的生产成本低，"铜地"将出口铜，该行业将扩大。
这个题目怎么分段，我都找不到主谓宾了，我理解的怎么跟解释是相反的
