If there is an oil-supply disruption resulting in higher international oil prices, domestic oil prices in
open-market countries such as the United States will rise as well, whether such countries import all or none of
their oil.
Which of the following conclusions is best supported by the statement in the passage?
A. Domestic producers of oil in open-market countries are excluded from the international oil market when
there is a disruption in the international oil supply.
B. International oil-supply disruptions have little, if any, effect on the price of domestic oil as long as an
open-market country has domestic supplies capable of meeting domestic demand.
C. The oil market in an open-market country is actually part of the international oil market, even if most of that
country’s domestic oil is usually sold to consumers within its borders.
D. Open-market countries that export little or none of their oil can maintain stable domestic oil prices even
when international oil prices rise sharply.
E. If international oil prices rise, domestic distributors of oil in open-market countries will begin to import more
oil than they export.

26 ：
The average normal infant born in the United States weighs between twelve and fourteen pounds at the age
of three months. Therefore, if a three-month-old child weighs only ten pounds, its weight gain has been below
the United States average.
Which of the following indicates a flaw in the reasoning above?
A. Weight is only one measure of normal infant development.
B. Some three-month-old children weigh as much as seventeen pounds.
C. It is possible for a normal child to weigh ten pounds at birth.
D. The phrase “below average” does not necessarily mean insufficient.
E. Average weight gain is not the same as average weight.

27：
Red blood cells in which the malarial-fever parasite resides are eliminated from a person’s body after 120
days. Because the parasite cannot travel to a new generation of red blood cells, any fever that develops in a
person more than 120 days after that person has moved to a malaria-free region is not due to the malarial
parasite.
Which is the following, if true, most seriously weakens the conclusion above?
A. The fever caused by the malarial parasite may resemble the fever caused by flu viruses.
B. The anopheles mosquito, which is the principal insect carrier of the malarial parasite, has been eradicated in
many parts of the world.
C. Many malarial symptoms other than the fever, which can be suppressed with anti-malarial medication, can
reappear within 120 days after the medication is discontinued.
D. In some cases, the parasite that causes malarial fever travels to cells of the spleen, which are less
frequently eliminated from a person’s body than are red blood cells.
E. In any region infested with malaria-carrying mosquitoes, there are individuals who appear to be immune to
malaria.

28：
Fact 1: Television advertising is becoming less effective: the proportion of brand names promoted on
television that viewers of the advertising can recall is slowly decreasing.
Fact 2: Television viewers recall commercials aired first or last in a cluster of consecutive commercials far better
than they recall commercials aired somewhere in the middle.
Fact 2 would be most likely to contribute to an explanation of fact 1 if which of the following were also true?
A. The average television viewer currently recalls fewer than half the brand names promoted in commercials
he or she saw.
B. The total time allotted to the average cluster of consecutive television commercials is decreasing.
C. The average number of hours per day that people spend watching television is decreasing.
D. The average number of clusters of consecutive commercials per hour of television is increasing.
E. The average number of television commercials in a cluster of consecutive commercials is increasing.

我已近不知道哪些是重复的啦。。。囧。。。

原题：The following appeared as part of a recommendation from the business manager of a department store.

“Local clothing stores reported that their profits decreased, on average, for the three-month period between August 1 and October 31. Stores that sell products for the home reported that, on average, their profits increased during this same period. Clearly, consumers are choosing to buy products for their homes instead of clothing. To take advantage of this trend, we should reduce the size of our clothing departments and enlarge our home furnishings and household products departments.”

提供观点：

1、衣帽部利润↓和家具部利润↑同时发生但不一定有必然联系
2、三个月的时间太短不能用来得出结论
3、过去的趋势不一定能保证未来走向
4、样本不具有代表性

答案与解析：

答案： C E D E  

25.
If the oil market in an open-market country were independent, fluctuations in international oil prices would not
affect domestic oil prices. However, if the statement about oil-supply disruption is true, it is evidence that
domestic oil prices are dependent on the international market and hence that the domestic oil market is a part of
the international oil market. Therefore, C is the best answer. B and D are not supported, since each contradicts
the claim that an international oil-supply disruption will lead to rising oil prices in an open-market nation. Nor are
A and E supported, since the statement provides information only about the effect of disruption on oil prices, not
domestic producers or distributors.

26.
The evidence on which the conclusion is based concerns only average weight, but the conclusion concerns
average weight gain. Because there is not necessarily a connection between an absolute measurement-such as
weight-and a rate of increase-such as weight gain-this argument is flawed. The relevant reasoning error is
described in E, which is the best answer. Neither of A and D identifies a reasoning error in the passage, since the
passage makes no claim that weight is the only relevant measure of infant development in general, and no claim
about sufficiency. B and C are consistent with the claims in the passage, and neither identifies a flaw in the
argument.


27.
The passage concludes that, because the malarial parasite cannot reside in red blood cells for more than 120
days, the malarial parasite cannot cause fever more than 120 days after infection. However, according to D,
there is a site in the body where the parasite could reside for more than 120 days after infection. Therefore, D
weakens the conclusion and is the best answer. The resemblance between malarial-fever symptoms and those
of other diseases, the existence of other malarial symptoms, and the possibility of immunity to malaria are
irrelevant to the issue of the conditions under which malarial fever can occur. B provides confirmation for the
existence of malaria-free regions but does not otherwise bear on the conclusion.


28.
Because E indicates that the number of commercials in a cluster is increasing, it entails that proportionally more
commercials are aired in intermediate positions. Hence, E helps fact 2 explain fact 1 by showing that
increasingly more commercials are aired in positions in which viewers find them difficult to recall. E is the best
answer. A testifies to the ineffectiveness of television advertising but does not help fact 2 explain fact 1. B
indicates that fact 2 contradicts rather than explains fact 1, since it suggests that the number of commercials per
cluster is decreasing. C and D help to explain fact 1-by describing a change in viewing habits and a change in
programming-but neither relates fact 2 to fact 1.
