不懂这题的逻辑，求解！ Kernland imposes a high tariff on the export of unprocessed cashew nuts in order to ensure that the nuts are sold to domestic processing plants. If the tariff were lifted and unprocessed cashews were sold at world market prices, more farmers could profit by growing cashews. However, since all the processing plants are in urban areas, removing the tariff would seriously hamper the government’s effort to reduce urban unemployment over the next five years. Which of the following, if true, most seriously weakens the argument? A. Some of the by-products of processing cashews are used for manufacturing paints and plastics. B. Other countries in which cashews are processed subsidize their processing plants C. More people in Kernland are engaged in farming cashews than in processing them. D. Buying unprocessed cashews at lower than world market prices enables cashew processors in Kernland to sell processed nuts at competitive prices. E. A lack of profitable crops is driving an increasing number of small farmers in Kernland off their land and into the cities.

语法题目，请指定王文静老师回答。 问题语法讲义-修饰-第十题-Psychiatrist题目，我感觉选项A.B都是一样的意思，而且2个选项都没有问题，不知道该如何取舍。谢谢

老师，这道题怎么解的？我自己的理解是，速度慢的机器有1到3台，把每台多出来的1小时加在一起除4，求得的平均值就是小数点后的数字。所以求的平均值最小是0.25不可能是0.2因此选项A，7.2是不可能的。但是不知道这道题是不是这么理解的。

老师，这题答案是D，但我觉得是C。题中说大于10小于100的整数，应该是89个，掉到过来98+9，个位数是7

20题我计算是95页，但是答案是B，99页，不知道怎么算出来的。

老师25题答案给的是30%.可是我怎么算都应该是40%呢？我算错了吗？应该怎么算？

老师这道题没明白是什么意思

老师，第12题我没明白是什么意思

这个是Tina 老师在语法课上讲的一道题，不知道为什么搜不出来。想问一下，正确答案B 选项中的begun为什么不是过去分词引导的状语从句修饰the autographed quilt? Tina 老师在课上讲的是：begun是就近修饰名词fad的，我就很迷茫。我一直记得您讲过过去分词和现在分词作状语是修饰不到SVO 的O 上的，那这个为什么例外呢?谢谢您!
