今天在練習GWD30
檢討中有兩題CR還是有點不清楚@@
Q15:
Kernland imposes a high tariff on the export of unprocessed cashew nuts
in order to ensure that the nuts are sold to domestic processing plants.
If the tariff were lifted and unprocessed cashews were sold at world
market prices, more farmers could profit by growing cashews.
However, since all the processing plants are in urban areas, removing
the tariff would seriously hamper the government's effort to reduce
urban unemployment over the next five years.
Which of the following, if true, most seriously weakens the argument?
A. Some of the by-products of processing cashews are used for manufacturing
paints and plastics.
B. Other countries in which cashews are processed subsidize their processing
plants.
C. More people in Kernland are engaged in farming cashews than in processing
them.
D. Buying unprocessed cashews at lower than world market prices enables
cashew processors in Kernland to sell processed nuts at competitive prices.
E. A lack of profitable crops is driving an increasing number of small
farmers in Kernland off their land and into the cities.
答案給E
我是選到C
不太懂為何E可以削弱這個推論
是從哪個方向推論出來的呢?
Q28:
"In countries where automobile insurance includes compensation for whiplash
injuries sustained in automobile accidents, reports of having suffered such
injuries are twice as frequent as they are in countries where whiplash is not
covered."
Presently, no objective test for whiplash exists, so it is true
that spurious reports of whiplash injuries cannot be readily identified.
Nevertheless, "these facts do not warrant a conclusion that has been drawn by
some commentators":
that in the countries with the higher rates of reported
whiplash injuries, half of the reported cases are spurious.
Clearly, in countries where automobile insurance does not include
compensation for whiplash, people often have little incentive to
report whiplash injuries that they actually have suffered.
In the argument given, the two boldfaced portions play which of the following roles?
A.The first is a claim that the argument disputes; the second is a conclusion
that has been based on that claim.
B.The first is claim that has been used to support a position that the
argument accepts; the second is a position that the argument rejects.
C.The first is a finding whose accuracy is evaluated in the argument;
the second is the judgment reached by the argument concerning the accuracy
of the finding.
D.The first is a finding whose implications are at issue in the argument; the
second is the judgment reached by the argument concerning one alleged
implication.
E.The first is a finding, the explanation of which is at issue in the argument;
the second is an objection that has been raised against the explanation that
the argument defends.
答案是D
不太懂答案D的第2句是在說什麼?
還請大家指點
謝謝
