5. 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 placing limits on campaign spending?
(A) Such limits undemocratically, and thus indefensibly, restrict political competition by favoring incumbents.
(B) Such limits are currently set too high for actual campaign expenditures to be affected.
(C) 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.
(D) Such limits are determined separately for each election district on the basis of previous levels of campaign expenditures.
(E) Such limits in no way guarantee a candidate's ability to raise as much money as he or she is entitled to raise.
6. In 1974, Con美国GREss 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, Con美国GREss could significantly increase the number of marriages among such couples by revising the present income tax rates.英语作文
