GWD1-Q2: B
By merging its two publishing divisions, the company will increase 【their share of the country’s $21 billion book market from 6 percent to 10 percent, a market ranging】 from obscure textbooks to mass-market paperbacks.
B.from 6 percent to 10 percent its share of the $21 billion book market in the country, which ranges
E.to 10 percent from 6 percent its share of the country’s $21 billion book market, which ranges
答案是B但是我觉得B里的which指代不明，既然which和country更接近。
这题GWD答案错了，就是E，prep有原题

GWD1-Q7: C
A recent review of pay scales indicates 【that CEO’s now earn an average of 419 times more pay than blue-collar workers, compared to a ratio of 42 times】 in 1980.
A.that CEO’s now earn an average of 419 times more pay than blue-collar workers, compared to a ratio of 42 times
B.that, on average, CEO’s now earn 419 times the pay of blue-collar workers, a ratio that compares to 42 times
C.that, on average, CEO’s now earn 419 times the pay of blue-collar workers, as compared to 42 times their pay, the ratio
D.CEO’s who now earn on average 419 times more pay than blue-collar workers, as compared to 42 times their pay, the ratio
E.CEO’s now earning an average of 419 times the pay of blue-collar workers, compared to the ratio of 42 times
这题我的主要问题是，A选项中既然是419 times more, 也就意味着是420 times the pay of b-c workers..不是说不能改变原句的意思的么？
这个确实是一点疏忽，据ron说是因为出题人的数学不好~anyway，虽然说尽量不能改变原意，但是在其它的都有严重语法问题时，还是可以改变原意的~

GWD1-Q21:   B
【That twenty-one ceramic dog figurines were discovered during the excavating】 of a 1,000-year-old Hohokam village in Tempe, Arizona, has nearly doubled the number of these artifacts known to exist.

A.    That twenty-one ceramic dog figurines were discovered during the excavating
B.    Twenty-one ceramic dog figurines discovered at the excavation
答案说A的tense不对 这里为何不能用past tense?
A中最大的错误不是tense，而是逻辑错误，句子简化来看就是：that句子 double the number,一个句子怎么可能double the number~关于时态，我觉得没什么问题啊~不过我对时态的把握也不太好，不是很肯定~但是有一点我很确定;除了明显的时态错误（像过去完成时那种经常出现的错误之外），一般不以时态作为split点~

GWD1-Q23:  D
Past assessments of the Brazilian rain forest have used satellite images to tally deforested areas, where farmers and ranchers have clear-cut and burned all the trees, but such work has not addressed either logging, 【which is the removal of only selected trees, as well as surface fires, burning】 down individual trees but do not denude the forest.
B.    which removes only selected trees, or surface fires that burn
D.    removing only selected trees, or surface fires, burning
我选了D，所以modifier部分不用平衡么？
