66. To protect certain ?edgling industries, the government of Country Z banned imports of the types of produc those industries were starting to make. As a direct result, the cost of those products to the buyers, several export-dependent industries in Z, went up, sharply limiting the ability of those industries to compete effectively in their export markets.
Which of the following conclusions about Country Z’s adversely affected export-dependent industries is be
supported by the passage?
(A) Pro?t margins in those industries were not high enough to absorb the rise in costs mentioned above.
(B) Those industries had to contend with the fact that other countries banned imports from Country Z.
(C) Those industries succeeded in expanding the domestic market for their products.
(D) Steps to offset rising materials costs by decreasing labor costs were taken in those industries.
(E) Those industries started to move into export markets that they had previously judged unpro?table.

我对A选项的例子是行业利润不够高，无法吸收上述成本的上升。
原文中说的是买家的成本上升，消减了产品在出口行业的竞争力。不知道是不是因为我对标红字的这句句子的理解有误。我觉得原文推导不出A选项，买家的成本上升是因为制造商的成本上升。而这种上升与行业利润的直接关系是怎么推导出来的呢，除非有个隐含的假设就是只有厂商不亏本，就不提价？

另外感觉profit margin=(卖出价-成本）/销售数量原文中只说了成本
profit margin在原文中未正式提及，profit margin不是out of scope了吗？

GMAT assumes that the testers know the definition of profit margin as COMMON sense. After all, GMAT is for those who want to work in the financial industry. If a tester does not have common sense or basic knowledge of financial transaction, he or she is unlikely to become a successful MBA student.
