标题: 请大虾帮忙！！ GWD31 02-Q33 and Q27

Q33:

When an active tooth in the shark’s jaws is lost or worn
down, many spare teeth lie in seemingly limitless reserve, each of which are
ready to slide into the appropriate position.

When an active tooth in the
   shark’s jaws is lost or worn down, many spare teeth lie in seemingly
   limitless reserve, each of which are ready to slide into the appropriate
   position.

答案是A，可我看E也没错啊。。。。请指点~~~

还有就是逻辑：　

Q27:

Rye
sown in the fall and plowed into the soil in early spring leaves a residue that
is highly effective at controlling broad-leaved weeds, but unfortunately for
only about 45 days. No major
agricultural crop matures from seed in as little as 45 days. Synthetic herbicides, on the other hand,
although not any longer-lasting, can be reapplied as the crop grows. Clearly, therefore, for major agricultural
crops, plowing rye into the soil can play no part in effective weed control.

The argument is most vulnerable to the objection that it
fails to

consider that there might be minor, quick-growing crops that do
mature in 45 days or less
identify any alternative
method of weed control that could be used instead of the method it rejects
distinguish among the various
kinds of synthetic herbicides
allow for the possibility of
combining the two weed-control methods it mentions
allow for the possibility
that plants other than rye, handled the same way, might have the same
effect

Answer:

我选了D，因为在文章中结论已定SCOPE为 “major agriculture crops"，所以有没有这种minor crop 不就和作者要做的结论没关系了吗？

没几天就要考试了，特别急着弄懂这些题目。。。谢谢了！！
