2. Low-income families are often unable to afford as much child care as they need. One government program would award low-income families a refund on the income taxes they pay of as much as $1,000 for each child under age four. This program would make it possible for all low-income families with children under age four to obtain more child care than they otherwise would have been able to afford.
Which of the following, if true, most seriously calls into question the claim that the program would make it possible for all low-income families to obtain more child care?
(A) The average family with children under age four spends more than $1,000 a year on child care.
(B) Some low-income families in which one of the parents is usually available to care for children under age four may not want to spend their income tax refund on child care.
(C) The reduction in government revenues stemming from the income tax refund will necessitate cuts in other government programs, such as grants for higher education.
(D) Many low-income families with children under age four do not pay any income taxes because their total income is too low to be subject to such taxes.（D）
(E) Income taxes have increased substantially over the past twenty years, reducing the money that low-income families have available to spend on child care.
我选的B，D也对，但是B也没有什么问题啊，不知道为什么就不对？
3． In the effort to fire a Civil Service employee, his or her manager may have to spend up to $100,000 of tax money. Since Civil Service employees know how hard it is to fire them, they tend to loaf.

III.
Most government workers are Civil Service employees.
(A) I only
(B) I and III only
(C) II only
(D) I, II, and III（A）
(E) III only
为什么III不对？是因为只能说大多数Civil Service employees是government workers而不能反过来吗？
