1. GWD-26-Q10
Lawmaker: Raising taxes is not the only means of reducing government
debt. The government’s stockpile of helium is worth 25 percent more,
at current market prices, than the debt accumulated in acquiring and
storing it. Therefore, by selling the helium, the government can not
only pay off that debt but reduce its overall debt as well.
Which of the following is an assumption on which the argument depends?
A. The government has no current need for helium.
B. Twenty-five percent of the debt the government has accumulated in
Stockpiling helium is not an insignificant portion of the government’s
Total debt.
C. It is not in the lawmaker’s interest to advocate raising taxes as a
Means of reducing government debt.
D. Attempts to sell the government’s helium will not depress the market
Price of helium by more than 25 percent.
E. The government will not incur any costs in closing its facilities for
stockpiling helium.
2. GWD-26-Q29
Educational Theorist: Recent editorials have called for limits on the amount
of homework assigned to children. They point out that free-time activities
play an important role in childhood development and that large amounts of
homework reduce children’s free time, hindering their development. But the
average homework time for a ten year old, for example, is little more than
30 minutes per night. Clearly, therefore, there is no need to impose the
limits these editorials are calling for.
Which of the following is an assumption on which the educational theorist’s
argument relies?
A. The free-time activities that ten year olds engage in most are all
approximately equally effective at fostering development
B. Regularly doing homework assignments improves children’s academic
performance.
C. Individual teachers are not the best judges of how much homework to
assign the children they teach
D. In most schools, if not all, the homework assignments given are of a
length that does not diverge widely from the average.
E. Free-time activities rarely teach children skills or information that they
can use in their academic work.
3. GWD-28-Q9
Early in the twentieth century, Lake Konfa became very polluted. Recently fish populations have recovered as release of industrial pollutants has declined and the lake’s waters have become cleaner. Fears are now being voiced that the planned construction of an oil pipeline across the lake’s bottom might revive pollution and cause the fish population to decline again. However, a technology for preventing leaks is being installed. Therefore, provided this technology is effective, those fears are groundless.
The argument depends on assuming which of the following?
A: Apart from development related to the pipeline, there will be no new industrial development around the lake that will create renewed pollution in its waters.
B: Other than the possibility of a leak, there is no realistic pollution threat posed to the lake by the pipeline’s construction
C: There is no reason to believe that the leak-preventing technology would be ineffective when installed in the pipeline in Lake Konfa.
D: Damage to the lake’s fish populations would be the only harm that a leak of oil from the pipeline would cause.
E: The species of fish that are present in Lake Konfa now are the same as those that were in the lake before it was affected by pollution.
