题目：

Although the discount stores in Goreville's central shopping district are expected to close within five years as a result of competition from a SpendLess discount department store that just opened, those locations will not stay vacant for long.  In the five years since the opening of Colson's, a nondiscount department store, a new store has opened at the location of every store in the shopping district that closed because it could not compete with Colson's.
 
Which of the following, if true, most seriously weakens the argument?

选项:

A、Many customers of Colson's are expected to do less shopping there than they did before the SpendLess store opened.
B、Increasingly, the stores that have opened in the central shopping district since Colson's opened have been discount stores.
C、At present, the central shopping district has as many stores operating in it as it ever had.
D、Over the course of the next five years, it is expected that Goreville's population will grow at a faster rate than it has for the past several decades.

题目：

In general, jobs are harder to get in times of economic recession because many businesses cut back operations.  However, any future recessions in Vargonia will probably not reduce the availability of teaching jobs at government-funded schools.  This is because Vargonia has just introduced a legal requirement that education in government-funded schools be available, free of charge, to all Vargonian children regardless of the state of the economy, and that current student-teacher ratios not be exceeded.
 
Which of the following, if true, most strengthens the argument?

选项:

A、The current student-teacher ratio at Vargonia's government-funded schools is higher than it was during the most recent period of economic recession.
B、During recent periods when the Vargonian economy has been strong, almost 25 percent of Vargonian children have attended privately funded schools, many of which charge substantial fees.
C、Nearly 20 percent more teachers are currently employed in Vargonia's government-funded schools than had been employed in those schools in the period before the last economic recession.
D、Teachers in Vargonia's government-funded schools are well paid relative to teachers in most privately funded schools in Vargonia, many of which rely heavily on part-time teachers.
E、During the last economic recession in Vargonia, the government permanently closed a number of the schools that it had funded.

题目：

Press Secretary:  Our critics claim that the President's recent highway project cancellations demonstrate a vindictive desire to punish legislative districts controlled by opposition parties.  They offer as evidence the fact that 90 percent of the projects canceled were in such districts.  But all of the canceled projects had been identified as wasteful in a report written by respected nonpartisan auditors.  So the President's choice was clearly motivated by sound budgetary policy, not partisan politics.
 
Which of the following is an assumption on which the press secretary's argument depends?

选项:

A、Canceling highway projects was not the only way for the President to punish legislative districts controlled by opposition parties.
B、The scheduled highway projects identified as wasteful in the report were not mostly projects in districts controlled by the President's party.
C、The number of projects canceled was a significant proportion of all the highway projects that were to be undertaken by the government in the near future.
D、The highway projects canceled in districts controlled by the President's party were not generally more expensive than the projects canceled in districts controlled by opposition parties.
E、Reports by nonpartisan auditors are not generally regarded by the opposition parties as a source of objective assessments of government projects.

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?
