Mayor Delmont’s critics complain about the jobs that were
lost in the city under Delmont’s leadership. 
Yet the fact is that not only were more jobs created than were
eliminated, but the average pay for these new jobs has been higher than the
average pay for jobs citywide every year since Delmont took office.  So there can be no question that throughout
Delmont’s tenure the average paycheck in this city has been getting steadily
bigger.

Which of the following, if true, most strengthens the
argument in the advertisement?

1. The
        average pay for jobs created in the city during the past three years was
        higher than the average pay for jobs created in the city earlier in Mayor
        Delmont’s tenure.
2. Average
        pay in the city was at a ten-year low when Mayor Delmont took office.
3. Some
        of the jobs created in the city during Mayor Delmont’s tenure have in the
        meantime been eliminated again.
4. The
        average pay for jobs eliminated in the city during Mayor Delmont’s tenure
        has been roughly equal every year to the average pay for jobs citywide.
5. The
        average pay for jobs in the city is currently higher than it is for jobs
        in the suburbs surrounding the city. 

Q15: （我选的D，
            觉得E和D一样的牵强阿）

Capuchin monkeys often rub their bodies with a certain type
of millipede.  Laboratory tests show that
secretions from the bodies of these millipedes（千足虫） are rich in two
chemicals that are potent mosquito repellents, and mosquitoes carry parasites
that debilitate capuchins.  Some
scientists hypothesize that the monkeys rub their bodies with the millipedes
because doing so helps protect them from mosquitoes.
            

Which of the following, if true, provides the most support
for the scientists’ hypothesis?

1. A
        single millipede often gets passed around among several capuchins, all of
        whom rub their bodies with it.
2. The
        two chemicals that repel mosquitoes also repel several other varieties of
        insects.
3. The
        capuchins rarely rub their bodies with the millipedes except during the
        rainy season, when mosquito populations are at their peak.
4. Although
        the capuchins eat several species of insects, they do not eat the type of
        millipede they use to rub their bodies.
5. The
        two insect-repelling chemicals in the secretions of the millipedes are
        carcinogenic
               （致癌的）
        for humans but do not appear to be carcinogenic for capuchins.
                   
   

Q20: (C为什么是weaken呢)

Five years ago, as part of a plan to encourage citizens of
Levaska to increase the amount of money they put into savings, Levaska’s
government introduced special savings accounts in which up to $3,000 a year can be saved with no tax due
on the interest unless money is withdrawn before the account holder reaches the
age of sixty-five.  Millions of dollars
have accumulated in the special accounts, so the government’s plan is obviously
working.

Which of the following, if true, most seriously weakens the
argument?
            

1. A
        substantial number of Levaskans have withdrawn at least some of the money
        they had invested in the special accounts.
2. Workers
        in Levaska who already save money in long-term tax-free accounts that are
        offered through their workplace cannot take advantage of the special
        savings accounts introduced by the government.
3. The
        rate at which interest earned on money deposited in regular savings
        accounts is taxed depends on the income bracket of the account holder.
4. Many Levaskans who already had
        long-term savings have steadily been transferring those savings into the
        special accounts.
5. Many
        of the economists who now claim that the government’s plan has been successful
        criticized it when it was introduced.

Q21:（不懂！！！
            这是啥逻辑呢）

An overwhelming proportion of the most productive employees
at SaleCo’s regional offices work not eight hours a day, five days a week, as
do other SaleCo employees, but rather ten hours a day, four days a week, with
Friday off.  Noting this phenomenon,
SaleCo’s president plans to increase overall productivity by keeping the
offices closed on Fridays and having all employees work the same schedule—ten
hours a day, four days a week.
            

Which of the following, if true, provides the most reason to
doubt that the president’s plan, if implemented, will achieve its stated
purpose?

1. Typically,
        a SaleCo employee’s least productive hours in the workplace are the early
        afternoon hours.
2. None
        of the employees who work four days a week had volunteered to work that
        schedule, but all were assigned to it by their supervisors.
3. Working ten hours a day has allowed
        the most productive employees to work two hours alone each day in their
        respective offices relatively undisturbed by fellow employees.
4. Employees
        at SaleCo are compensated not on the basis of how many hours a week they
        work but on the basis of how productive they are during the hours they are
        at work.
5. Those
        SaleCo employees who have a four-day workweek do not take any of their
        office work to do at home on Fridays.
                       
   

Q40:　（如果用排除法，可以选出是Ｄ，但仍不太明白Ｄ和原文的联系）

It is theoretically possible that bacteria developed on Mars
early in its history and that some were carried to Earth by a meteorite.  However, strains of bacteria from different
planets would probably have substantial differences in protein structure that
would persist over time, and no two bacterial strains on Earth are different
enough to have arisen on different planets. 
So, even if bacteria did arrive on Earth from Mars, they must have died
out.

The argument is most vulnerable to which of the following
criticisms?
            

1. It
        fails to establish whether bacteria actually developed
               （无关）on
        Mars.
2. It
        fails to establish how likely it is that Martian bacteria were transported
        to Earth.　（无关，而且已经告诉你了by a
        meteorite）
3. It
        fails to consider whether there were means other than meteorites by which
        Martian bacteria could have been carried to Earth.
4. It
        fails to consider whether all bacteria now on Earth could have arisen from
        transported Martian bacteria. 　（如果是arise from，那么就是变形了，所以不算die
        out？）
5. It
        fails to consider whether there could have been strains of bacteria that
        originated on Earth and later died out. (无关)
