In the country of Veltria, the past two years' broad economic recession has included a business downturn in the clothing trade, where sales are down by about 7 percent as compared to two years ago. Clothing wholesalers have found, however, that the proportion of credit extended to retailers that was paid off on time fell sharply in the first year of the recession but returned to its prerecession level in the second year. Which of the following, if true, most helps to explain the change between the first and the second year of the recession in the proportion of credit not paid off on time? (A) The total amount of credit extended to retailers by clothing wholesalers increased between the first year of the recession and the second year. (B) Between the first and second years of the recession, clothing retailers in Veltria saw many of their costs, rent and utilities in particular, increase. (C) Of the considerable number of clothing retailers in Veltria who were having financial difficulties before the start of the recession, virtually all were forced to go out of business during its first year. (D) Clothing retailers in Veltria attempted to stimulate sales in the second year of the recession by discounting merchandise. (E) Relatively recession-proof segments of the clothing trade, such as work clothes, did not suffer any decrease in sales during the first year of the recession. 这道题错选了A。 思路如下： 题目问的是为什么在经济不好，衣服卖不动的情况下，第一年零售商还不上钱第二年就能还上了。讲的是零售商还钱的问题。 当时留下的是A,C,D 排除D是因为觉得，即使刺激销售量衣服打折也不能说明能还上钱。可能打折卖1块，纵使家当全卖了也不够。 排除C是因为觉得， 那些本身经济状况就很差的在第一年被淘汰掉以后，剩下的那些没说经济状况如何啊，如果也不咋地，第二年还是得淘汰啊。 A选项当时觉得，即使credit extended，对pay off on time也无太大用处，但最起码跟原文意思接近。所以选了A。

请问may老师此题思路

想问一下这道题怎么理解？

关于平行比较，前三句是一个问题，我不太明白这个比较后面的did/is的位置，为何有的放在代词前有的在代词后？比如前两句，did可否放在those are后面？ 最后那句话是否平行呢，that of course可都指代social structure，谢谢 此外，还有句i have more apples than eric‘s apples这句宾语比较是否正确呢？

语法！老师，我想问一下，这几个的区别 Taste buds are xxx，each of them has x. 是错的，each of them has x 这里是一个单独的句子 Taste buds are xxx，each of which has xxx.对了，each这个句子是定语从句吗？还是同位语从句？ Taste buds are xxx，each has…跟each of them has ……是一样的吗 Taste buds are xxx，each having…是同位语修饰吗
