实在不好意思可能是这道题太简单了，都没有人问过。。。

15. The cost of producing radios in Country Q is ten percent less than the cost of producing radios in Country Y. Even after transportation fees and tariff charges are added, it is still cheaper for a company to import radios from Country Q to Country Y than to produce radios in Country Y.

The statements above, if true, best support which of the following assertions?

A. labor costs in Country Q are ten percent below those in Country Y.

B. importing radios from Country Q to Country Y will eliminate ten percent of the manufacturing jobs in Country Y.

C. the tariff on a radio imported from Country Q to Country Y is less than ten percent of the cost of manufacturing the radio in Country Y.

D. the fee for transporting a radio from Country Q to Country Y is more than ten percent of the cost of manufacturing the radio in Country Q. C

E. it takes ten percent less time to manufacture a radios in Country Q than it does in Country Y.

15.

If the tariff on importing radios from Country Q to Country Y were as high as ten percent or more of the cost of producing radios in Y, then, contrary to what the passage says, the cost of importing radios from Q to Y would be equal to or more than the cost of producing radios in Y. thus, the tariff cannot be that high, and C is the best answer.

A and E give possible partial explanations for the cost difference, but neither is supported by the passage because the cost advantage in Q might be attributable to other factors. B and D are both consistent with the information in the passage, but the passage provides no evidence to support them.

我的思路是将有原文中没出现的内容的选项选项排除，这样就只剩下C了。

但是看了og的解释有一点不明白，下面的是什么意思呢？：）

B and D are both consistent with the information in the passage, but the passage provides no evidence to support them.

盼解答！谢谢！：）
