Q14:
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.

Correct ans: C

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

Correct ans: C

Evidence: (1) nos of jobs eliminated (say n1) < nos of jobs created (say n2) ; (2) avg pay for new job higher increasing every year. Lets say pay for job elimintated p1 and that for new job p2

Conclusion: avg paycheck increased (equivalent to product of nos of job and avg pay for that job). Note that there is a shift from new jobs in evidence to paycheck for avg job in the city.

This means product of n1p1 < n2p2, but there is no evidence for relation between p1 & p2 and so tht must be assumed
pay for job eliminated < or = pay for new job created ie p1 <= p2. The same is mentioned in choice D, which affirms this assumption strengthening the agrument.

IMO D. Choice C actually weakens the agrument - as older job & new jobs both are eliminated leading to overall decrease in total nos of jobs
