1、 Teenagers are often priced out of the labor market by the government-mandated minimum-wage level because employers cannot afford to pay that much for extra help. Therefore, if Congress institutes a subminimum wage, a new lower legal wage for teenagers, the teenage unemployment rate, which has been rising since 1960, will no longer increase.

Which of the following, if true, would most weaken the argument above?

(A) Since 1960 the teenage unemployment rate has risen when the minimum wage has risen.

(B) Since 1960 the teenage unemployment rate has risen even when the minimum wage remained constant.

(D) The teenage unemployment rate rose more quickly in the 1970’s than it did in the 1960’s.

(E) The teenage unemployment rate has occasionally declined in the years since 1960.

2、

Which of the following best completes the passage below?

(A) many users who illegally copy programs never find any use for them

(B) most of the illegally copied programs would not be purchased even if purchasing them were the only way to obtain them

(C) even if the computer industry received all the revenue it claims to be losing, it would still be experiencing financial difficulties

(D) the total market value of all illegal copies is low in comparison to the total revenue of the computer industry
