Political Advertisement:



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?



A. 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.

B. Average pay in the city was at a ten-year low when Mayor Delmont took office.

C. Some of the jobs created in the city during Mayor Delmont’s tenure have in the meantime been eliminated again.

D. 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.

E    The average pay for jobs in the city is currently higher than it is for jobs in the suburbs surrounding the city.




D is the right answer. but what does it mean? why the pay of jobs which has been eliminated equal to the citywide pay of job  strengthen the argument?

my understanding is since 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,

we can conclude that new jobs were created and the average pay for these new jobs has been higher than the average pay for jobs

sry, i still didn't get it. u mean after we eliminate the some job, the average pay is still equal to the original one? that can prove it is higher before? i am so stupid, plz forgive me.

It just means that,during the period when MAYOR D is in charge, the average pay of the jobs he created is truly higher than that of those elimated jobs. Otherwise, suppose the situation is the opposite, then we may conclude that the average pay would rather higer if those jobs are not elimated, given the pay of those ones are higher.

In sum ,only when the pay of the new job is higher than that of the elimated ones can we say that the pay now is higher than in the past.
