1.A thorough search of Edgar Allan Poe's correspon-
dence has turned up not a single letter in which he
mentions his reputed morphine addiction. On the basis
of this evidence it is safe to say that Poe's reputation
for having been a morphine addict is undeserved and
that reports of his supposed addiction are untrue.
Which of the following is assumed by the argument
above?
(A) Reports claiming that Poe was addicted to mor-
phine did not begin to circulate until after his
death.
(B) None of the reports of Poe's supposed morphine
addiction can be traced to individuals who actu-
ally knew Poe.
(C) Poe's income from writing would not have been
sufficient to support a morphine addiction.
(D) Poe would have been unable to carry on an
extensive correspondence while under the
influence of morphine.
(E) Fear of the consequences would not have pre-
vented Poe from indicating in his correspon-
dence that he was addicted to morphine.

2.People whose bodies cannot produce the substance
cytochrome P450 are three times as likely to develop
Parkinson's disease, a disease that affects the brain,
as are people whose bodies do produce this substance.
Since cytochrome P450 protects the brain from toxic
chemicals, toxic chemicals probably play a role in the
development of Parkinson's disease.
Which of the following, if true, most strongly
supports the argument？
(A)It will soon be possible for cytochrome P450 to
be synthesized for the treatment of people
whose bodies cannot produce this substance.
(B)Many people whose bodies are unable to
produce cytochrome P450 lack the ability to
produce certain other substances as well.
(C)Cytochrome P450 has no effect on the brain
other than to protect it from toxic chemicals.
(D)People with Parkinson's disease often exhibit a
marked lessening in the severity of their symp-
toms when they are treated with dopamine, a
chemical produced naturally in the brain.
(E)Many people with Parkinson's disease have the
ability to produce cytochrome P450 naturally

3.Excluding purchases by businesses, the average
amount spent on a factory-new car has risen 30 per-
cent in the last five years. In the average household
budget, the proportion spent on car purchases has
remained unchanged in that period. Therefore the
average household budget must have increased by
30 percent over the last five years.
Which of the following is an assumption on which
the argument relies？
(A)The average number of factory-new cars pur-
chased per household has remained unchanged
over the last five years.
(B)The average amount spent per car by businesses
buying factory-new cars has risen 30 percent in
the last five years.
(C)The proportion of the average household budget
spent on all car-related expenses has remained
unchanged over the last five years.
(D)The proportion of the average household budget
spent on food and housing has remained
unchanged over the last five years.
(E)The total amount spent nationwide on factory-
new cars has increased by 30 percent over the
last five years.

第一题说，对Poe通信的彻底调查发现根本没提到鸦片的事情，所以他吸鸦片的坏名声是假的。
这里面就隐含了一个问题，如果他真的吸鸦片，但不好意思在通信里承认呢？？所以E选项就是这个argument的一个assumption

第二题，细胞色素P450除了保护大脑免遭有毒化学物侵害，就没别的什么用处了

第三题的argument是，过去五年，每辆车的花费增长了30%，但在车上的花费在家庭预算里的比重没变，所以家庭预算增长了30%。
A选项是过去5年每个家庭拥有的车的数量没变。
逻辑是这样的，每辆车的花费增加了30%，但在家庭支出中的比重没变。如果车的数量减少了50%，这就根本推不出家庭收入的增长，所以必须保证车的数量没有变，也就是家庭在车上的总花费增长了，才能推出家庭收入的增长。
