答案：(D)
Political campaigns to win election to an office are much more costly than
campaigns to retain an office. Two separate econometric studies made three
years ago found that a challenger’s campaign expenditures would have to exceed
those of the incumbent by $200,000 to make a difference. And this is just an
average figure. Since campaign expenses differ widely from election district
to election district, there will be individual districts where this figure is
considerable higher.

The information above provides which of the following reasons for not placinglimits on campaign spending?
Such limits undemocratically, and thus indefensibly, restrict political
competition by favoring incumbents.
Such limits are currently set too high for actual campaign expenditures
to be affected.
Such limits run counter to the stilit of constitutional granaries of an
individual’s right to act freely as long as nobody else’s rights are abridged.
Such limits are determined separately for each election district on the
basis of previous levels of campaign expenditures.
Such limits in no way guarantee a candidate’s ability to raise as much
money as he or she is entitled to raise.

答案：(A)
In 1974, Congress reduced the income tax rates for single persons. This change
had the effect of penalizing married couples with two incomes, because they then
were required to pay more in taxes than they would have if they had remained
single.Since 1974, there has been a 149 percent increase in the number of
unmarried couples living together. Therefore, Congress could significantly
increase the number of marriages among such couples by revising the present
income tax rates.
The main flaw in the reasoning in the passage above is that it
suggests that Congress revamp current income tax laws to favor married
couples with two incomes
assumes that Congress intentionally penalized married couples when it
required that they pay higher income taxes than single people.
suggests that Congress should consider now its income tax legislation
affects ail segments of the population
suggests that current income tax law, rather than one or more other
factors, is responsible for the increase in the number of unmarried couples
living together
assumes that current income tax rates determine whether or not most married
couples choose to remain married

答案：(D)
Cars made in the United States average 21.5 miles per gallon of gas, whereas
imported cars average 30.5 miles per gallon. Therefore, owners of cars made in
the United States spend substantially more for gas than do owners of imported
cars. As a result, the automobile industry in the United States is losing a
significant portion of the car market to foreign car makers.
The passage above presupposes that
imported cars are better engineered than most cars made in the United States
automobile buyers in the United States are eager to preserve dwindling
petroleum resources
the cost of operation is an important consideration for those who buy
automobiles
imported cars and cars made in the United States cost approximately the
same amount
the automobile industry in the United States will continue to lose a
significant portion of the car market to foreign car makers
