题目：

A year ago, Dietz Foods launched a yearlong advertising campaign for its canned tuna. Last year Dietz sold 12 million cans of tuna compared to the 10 million sold during the previous year, an increase directly attributable to new customers brought in by the campaign. Profits from the additional sales, however, were substantially less than the cost of the advertising campaign. Clearly, therefore, the campaign did nothing to further Dietz’s economic interests.

Which of the following, if true, most seriously weakens the argument?

选项:

A、Sales of canned tuna account for a relatively small percentage of Dietz Foods’ profits.
B、Most of the people who bought Dietz’s canned tuna for the first time as a result of the campaign were already loyal customers of other Dietz products.
C、A less expensive advertising campaign would have brought in significantly fewer new customers for Dietz’s canned tuna than did the campaign Dietz Foods launched last year.
D、Dietz made money on sales of canned tuna last year.
E、In each of the past five years, there was a steep, industry-wide decline in sales of canned tuna.

答案:

E

题目：

One summer, floods covered low-lying garlic fields situated in a region with a large mosquito population. Since mosquitoes lay their eggs in standing water, flooded fields would normally attract mosquitoes, yet no mosquitoes were found in the fields. Diallyl sulfide, a major component of garlic, is known to repel several species of insects, including mosquitoes, so it is likely that diallyl sulfide from the garlic repelled the mosquitoes.

Which of the following, if true, most strengthens the argument?

选项:

A、Diallyl sulfide is also found in onions but at concentrations lower than in garlic.
B、The mosquito population of the region as a whole was significantly smaller during the year in which the flooding took place than it had been in previous years.
C、By the end of the summer, most of the garlic plants in the flooded fields had been killed by waterborne fungi.
D、Many insect species not repelled by diallyl sulfide were found in the flooded garlic fields throughout the summer.
E、Mosquitoes are known to be susceptible to toxins in plants other than garlic, such as marigolds.

C、there were no issues other than crime, unemployment, and pollution on which the candidates had significant differences of opinion

题目：

Scientists typically do their most creative work before the age of forty.  It is commonly thought that this happens because aging by itself brings about a loss of creative capacity.  However, a study has found that almost all scientists who produce highly creative work beyond the age of forty entered their fields late and less than a dozen years before their creative breakthroughs.  Since creative breakthroughs by scientists under forty also generally occur within a dozen years of the scientist's entry into the field, the study's finding strongly suggests that the real reason why scientists over forty rarely produce highly creative work is not due to age but rather because most have spent too long in their fields.
 
In the argument given, the two portions in boldface play which of the following roles?

选项:

A、The first is the position that the argument as a whole defends; the second is evidence that is advanced as part of that defense.
B、The first and second are both claims that have been advanced in support of a position that the argument as a whole opposes.
C、The first is an explanation that the argument challenges; the second provides evidence in support of a competing explanation that the argument defends.
D、The first is an explanation that the argument challenges; the second is evidence that has been used against an alternative explanation that the argument defends.
E、The first is an explanation that the argument defends; the second is evidence that has been used to challenge that explanation.

文章：

Line Behind every book review there are two key figures:
a book review editor and a reviewer. Editors decide
whether a book is reviewed in their publication, when
the review appears, how long it is, and who writes the
(5) review.
When many periodicals feature the same books,
this does not prove that the editors of different
periodicals have not made individual decisions.
Before publication, editors receive news releases and
(10) printer’s proofs of certain books, signifying that the
publishers will make special efforts to promote these
books. They will be heavily advertised and probably
be among the books that most bookstores order in
quantity. Not having such books reviewed might give
(15) the impression that the editor was caught napping,
whereas too many reviews of books that readers will
have trouble finding in stores would be inappropriate.
Editors can risk having a few of the less popular
titles reviewed, but they must consider what will be
(20) newsworthy, advertised, and written about elsewhere.
If these were the only factors influencing editors,
few books that stand little chance of selling well would
ever be reviewed. But editors feel some concern
about what might endure, and therefore listen to
(25) literary experts. A generation ago, a newspaper used
a brilliant system of choosing which books to feature.
The book review editor sent out a greater number of
books than reviews he actually intended to publish.
If a review was unenthusiastic, he reasoned that the
(30) book was not important enough to be discussed
immediately, and if good reviews of enough other
books came in, the unenthusiastic review might never
be printed. The unenthusiastic reviewers were paid
promptly anyway, but they learned that if they wanted
(35) their material to be printed, it was advisable to be
kind.
Most editors print favorable and unfavorable
reviews; however, the content of the review may be
influenced by the editor. Some editors would actually
(40) feel that they had failed in their responsibility if they
gave books by authors they admired to hostile critics
or books by authors they disapproved of to critics
who might favor them. Editors usually can predict who
would review a book enthusiastically and who would
(45) tear it to shreds.

D、What criteria are used to determine the length of a particular book review?

Art historian: Unlike many artistic traditions that sought to depict plants native to the local area in a seasonally appropriate way (for example, depicting scenes of spring with the plants in the appropriate stages of development for that season), seventeenth-century Dutch artists specializing in flower paintings almost exclusively chose to depict exotic species of flowers from outside the local area. Painting such species was worthwhile primarily because the art-buying public had developed a strong preference for images of the exotic. The great botanical centers of the time gave the artists direct access to such flowers, which the artists would freely combine in a single painting, regardless of whether the combined species occurred together in the wild, and depicted each in full bloom, regardless of whether those species bloomed at the same time in nature.

Statement: The art historian makes the point that the species of flowers these Dutch artists chose to paint were 1 largely because the species were 2 .

Select for 1 and for 2 the options that complete the statement so that it is most strongly supported by the information provided. Make only two selections, one in each column.

Tiger beetles are such fast runners that they can capture virtually any nonflying insect.  However, when running toward an insect, the beetles intermittently stop, and then, a moment later, resume their attack.  Perhaps they cannot maintain their pace and must pause for a moment's rest; but an alternative hypothesis is that while running tiger beetles are unable to process the resulting rapidly changing visual information, and so quickly go blind and stop.
 
Which of the following, if discovered in experiments using artificially moved prey insects, would support one of the two hypotheses and undermine the other?
