Test1 16
16.In a political system with only two major parties, the entrance of a third-party candidate into an election race damages the chances of only one of the two major candidates. The third-party candidate always attracts some of the voters who might otherwise have voted for one of the two major candidates, but not voters who support the other candidate. Since a third-party candidacy affects the two major candidates unequally, for reasons neither of them has any control over, the practice is unfair and should not be allowed.
If the factual information in the passage above is true, which of the following can be most reliably inferred from it?
(A) If the political platform of the third party is a compromise position between that of the two major parties, the third party will draw its voters equally from the two major parties.
(B) If, before the emergence of a third party, voters were divided equally between the two major parties, neither of the major parties is likely to capture much more than one-half of the vote.
(C) A third-party candidate will not capture the votes of new voters who have never voted for candidates of either of the two major parties.
(D) The political stance of a third party will be more radical than that of either of the two major parties.
(E) The founders of a third party are likely to be a coalition consisting of former leaders of the two major parties.

8.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.
(C) Employers often hire extra help during holiday and warm weather seasons.
(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.
为什么选B？
20.For a local government to outlaw all strikes by its workers is a costly mistake, because all its labor disputes must then be settled by binding arbitration, without any negotiated public-sector labor settlements guiding the arbitrators. Strikes should be outlawed only for categories of public-sector workers for whose services no acceptable substitute exists.
The statements above best support which of the following conclusions?
(A) Where public-service workers are permitted to strike, contract negotiations with those workers are typically settled without a strike.
(B) Where strikes by all categories of pubic-sector workers are outlawed, no acceptable substitutes for the services provided by any of those workers are available.
(C) Binding arbitration tends to be more advantageous for public-service workers where it is the only available means of settling labor disputes with such workers.
(D) Most categories of public-sector workers have no counterparts in the private sector.
(E) A strike by workers in a local government is unlikely to be settled without help from an arbitrator.

为什么选B？
  

青少年经常被政府规定的最少工资水平而排除在劳动力市场外，这是因为雇主不能对这种额外的帮助予以很多的工资。因此如果国会制定更低的最低工资（subminimum），一种新的对青少年合法的工资,那么自1960年开始的 the teenage unemployment rate将不会增加。
问消弱。
B，Since 1960 the teenage unemployment rate has risen even when the minimum wage remained constant。即使最低工资不变，青少年的不被雇佣比例 还是上升。
说明最低工资不是青少年的不被雇佣比例上升的直接原因。消弱了原文的论证关系。
