14. The economy is doing badly. First, the real estate
slump has been with us for some time. Second, car
sales are at their lowest in years. Of course, had either
one or the other phenomenon failed to occur, this
would be consistent with the economy as a whole
being healthy. But, their occurrence together makes it
quite probable that my conclusion is correct.
Which one of the following inferences is most strongly
supported by the information above?
(A) If car sales are at their lowest in years, then it is
likely that the economy is doing badly.
(B) If the economy is doing badly, then either the
real estate market or the car sales market is not
healthy.
(C) If the real estate market is healthy, then it is
likely that the economy as a whole is healthy.
(D) If the economy is in a healthy state, then it is
unlikely that the real estate and car sales
markets are both in a slump.
(E) The bad condition of the economy implies that
both the real estate and the car sales markets
are doing badly.

这道题目答案是D

可我觉得C也没错啊

20. Advertisement: Each of the Economic Merit Prize
winners from the past 25 years is covered by the
Acme retirement plan. Since the winners of the
nation’s most prestigious award for economists
have thus clearly recognized that the Acme plan
offers them a financially secure future, it is
probably a good plan for anyone with retirement
needs similar to theirs.
The advertisement’s argumentation is most vulnerable
to criticism on which one of the following grounds?
(A) It ignores the possibility that the majority of
Economic Merit Prize winners from previous
years used a retirement plan other than the
Acme plan.
(B) It fails to address adequately the possibility that
any of several retirement plans would be good
enough for, and offer a financially secure
future to, Economic Merit Prize winners.
(C) It appeals to the fact that supposed experts have
endorsed the argument’s main conclusion,
rather than appealing to direct evidence for that
conclusion.
(D) It takes for granted that some winners of the
Economic Merit Prize have deliberately
selected the Acme retirement plan, rather than
having had it chosen for them by their
employers.
(E) It presumes, without providing justification, that
each of the Economic Merit Prize winners has
retirement plan needs that are identical to the
advertisement’s intended audience’s retirement
plan needs.

这道题答案是D,可是我觉得D根本就不对啊.C更好些啊.

是不是自己选择的跟题目没关系嘛

14. 题目没有mention estate market healthy 这个概念，什么是healthy根本没说，所以c不对

20. 是不是assume了由于这些economists recognize,所以是他们自己的选择，所以it is
probably a good plan for anyone with retirement
needs similar to theirs. 而c中 expert没有认可此题中的conclusion (it is
probably a good plan for anyone with retirement
needs similar to theirs.)，而只是作者的一个推论

number 14

read both choice C and A , they are actually the same

when an inference question is asked

it is something what logically follows the argument, and it has to be 100% true to the argument.

the conclusion is that the economy is doing badly.

why? the supporting evidence is saying due to real estate and car sales markets are both doing badly.

so in other words, if the economy is doing well, then the reasl estate market and car sales market are both not in a slump.

and both A and C went backwards on the logical arrow of the argument.

20. you need to find the flaw in the argument.

Conclusion, the winners retirement plan are covered by ACME.

the flaw lies within the unseen unconsidered possbility.

just because they are experts, therefore THEY MUST CHOSE?  ask yourself how can you be sure that THEY CHOSE IT and not someone else ? how can you be sure that their judgements are ALWAYS correct?
