题目要解释“为什么产品好都不接受”
A 兽医已经在卖这些产品了，不代表不能接受。 说服力不好。 考试时想不清楚应该保留住。
C 中说服力强，生产商的产品在宠物店和超市随处可见。见一个插入语，unlike most equally good competing products sold by veterinarians, 强对比很好解释了paradox，是因为竞争力差，优选
有4个元素，a drastic fall in tax revenues，a reduction in military preparedness，the collapse of the currency system 和 to make sufficient investment in vital transportation infrastructure ，可见要不就是4个名词平行，要不就是前面3个名词平行，后面那个动词跟前面caused平行，以上只有E是4个名词平行
宗老板说：b选项的it主语指代不明+since的整句话可以去掉不应该这个句子的成立。应改成：birds had been overcome by pollution were routinely falling from the sky above Los Angeles freeways, and it prompted officials in California to devise a plan that would reduce
第三问 宗老板：We will honor our commitment to pay $50... 的情况下 However, we will need to try not to exceed the total amount that is budgeted for this purpose. 所以主要还是go的
选项：receiving popular and governmental support
原文：
popular support——She used sums raised through public contributions
governmental support——she succeeded in persuading the government to establish a Royal Commission on the Health of the Army.

C:居民不应该抱怨夜班飞机影响休息这件事

E选项取非：有的居民可以避免却没有避免买机场附近的房子。说明居民考虑到了后果，不应该抱怨，没有削弱结论。
