885-section D-06

6.     The main reasons for the phenomenal growth of agribusiness over the last fifteen years are because of elevated land prices, the basing of retail marketing networks on produce imported from other states, and decreased competition from developers.

(A) because of elevated land prices, the basing of retail marketing networks

(B) a result of elevated land prices, retail marketing networks based

(C) that land prices are elevated, retail marketing networks are based

(D) elevated land prices, retail marketing networks based

(E) because land prices are elevated, the basing of retail marketing networks

答案选D，但为什么C选项不对了？是因为没有the reason for that .....的句型吗？还是因为reatil marketing networks are based 中不应该加are

7.     Everyone participating in the early sociological study committed a crucial methodological error by failing to fully consider alternative ways of classifying their data.

(A) by failing to fully consider alternative ways of classifying their

(B) by failing fully to consider alternative ways of classifying their

(C) they failed to consider alternative ways to classify their

(D) by not fully considering alternative ways to classify the

(E) by not considering fully alternative ways of classifying his or her

A 为什么错了,感觉比D选项更合理，读起来更通顺一些哈

elevated land prices，retail marketing networks， decreased competition平行并列做宾语；

C用that引导宾语从句并列，不如D用短语并列简介，而且和and后的短语在结构上无法并列。

"elevated land prices" and "decreased competition" 我觉得这两个是并连的，但中间那个retail marketing networks are based on produce imported from other states, 是一句话哦

their 无所指
