The argument is that more jobs were created than were eliminated, but at the same time the overall average pay has gone up since the Mayor took office.

A out of scope
B strengthens a different argument, not the one above.
C weakens
D Correct. The avg of eliminated jobs = avg of city. So it stregthens the argument that the avg has gone up, coz the newly created jobs must be having a higher avg pay
E out of scope

Answer D

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. – Irrelevant
B. Average pay in the city was at a ten-year low when Mayor Delmont took office. – Hold on
C. Some of the jobs created in the city during Mayor Delmont’s tenure have in the meantime been eliminated again. – Weakens the argument
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. Eliminated Jobs is irrelevant
E. The average pay for jobs in the city is currently higher than it is for jobs in the suburbs surrounding the city. – Irrelevant


B!

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.

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


I feel A strengthens the argument by showing that the average pay for the jobs has been increasing ...

stated in stimulus
B. Average pay in the city was at a ten-year low when Mayor Delmont took office.
doesnt matter
C. Some of the jobs created in the city during Mayor Delmont’s tenure have in the meantime been eliminated again. weakens
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. Correct IMO, because the jobs that have been eliminated are average pay, the new jobs are higher pay, so the average pay is steadily climbing
E. The average pay for jobs in the city is currently higher than it is for jobs in the suburbs surrounding the city.OOS

This is a well designed question. It combines arithmetic (and the basic formula for an average) with subtle gaps in the argument's reasoning. Real managers in real businesses often make the kinds of mistakes that are built into the argument, so this is not just an academic exercise.

I think the most important thing to notice is that the conclusion is about average pay for ALL the jobs in the city, while the evidence tells us only about the number of jobs CREATED and LOST, and about the average pay for the jobs CREATED. It tells us nothing about the jobs which simply stayed there, which are probably the majority of jobs. It also doesn't tell us anything about the average pay for the jobs which were LOST.

So there are major holes in the argument's arithmetic. The average pay for the jobs created was greater than the average pay for ALL jobs, but this increase in total pay, whatever it is, was offset to an unknown degree by the total pay for the jobs LOST. If the average pay for the lost jobs was higher than the average pay for the new jobs (which is entirely possible, given the evidence), then the NET change in total pay divided by the NET change in jobs would be less than the previous average pay for all jobs. That would make average pay for all jobs go down, not up.

Another hole is that the evidence does not prevent the average pay for jobs that are NOT created or lost from going down over time. Even if the average pay for lost jobs was NOT higher than the average pay for new jobs, a decline in the average pay for the "stable" jobs could more than offset that change.

So to strengthen the argument, we need to plug one of these holes. Choice D is correct because it plugs the first hole: If the average pay for the lost jobs was equal to the average pay for all jobs, then it can't be higher than the average pay for the new jobs -- because the evidence tells us that the new jobs paid better (on average) than all jobs.

Note that (as often happens with strengthening questions) the correct answer doesn't prove the argument, but just IMproves it. In this case, D plugs one of the gaps. But because it still leaves us not knowing whether average pay for "stable" jobs remained the same, it does not prove the conclusion.

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 each year since Delmont took office the average pay for the new jobs created has been higher than that year’s average pay for jobs citywide. So it stands to reason that throughout Delmont’s tenure the average paycheck in this city has been getting steadily bigger.

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

A. The unemployment rate in the city is higher today than it was when Mayor Delmont took office.
B. The average pay for jobs in the city was at a ten-year low when Mayor Delmont took office.
C. Each year during Mayor Delmont’s tenure, the average pay for jobs that were eliminated has been higher than the average pay for jobs citywide.
D. Most of the jobs eliminated during Mayor Delmont’s tenure were in declining industries.
E. The average pay for jobs in the city is currently lower than it is for jobs in the suburbs surrounding the city.

Answer would be C. Conclusition of the argument is that the average pay is getting bigger because of the higher paying new jobs created during Mayor's leadership. And we are asked to find the one that weakens this argument and conclusion.
IF C is true, then the conclusion can't stand.

Yeah IMO D

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 --> three years is an indefinite time period and this just mentions about average pay for jobs created, not average pay for all jobs, so eliminate
B. Average pay in the city was at a ten-year low when Mayor Delmont took office -->no influence
C. Some of the jobs created in the city during Mayor Delmont’s tenure have in the meantime been eliminated again --> the same like B, too far to have an influence to the argument
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 --> the best. Imagine, A is average pay for job created, B is for job eliminated, C for job citywide. At the beginning of the year, the average pay for all jobs in the city are B + C; at the end of the year, because a number of jobs are eliminated (their average pay are B) and a number of job are created (their average are A), the average pay for all jobs in the city are A +C. Therefore, because A>C and B=C, (A+C) - (B+C) > 0 --> at the end end of the year, the average paycheck of all jobs in the city is bigger than it was at the beginning of the year. And this fact continues year after year (in the Delmont's tenure) because every jobs created in any year will have their average pays higher than that of jobs created in the year before but eliminated in that year.
E. The average pay for jobs in the city is currently higher than it is for jobs in the suburbs surrounding the city -->suburb is irrelevant

I am so convinced the answer is D and here is the reasoning -

Lets say the average pay of jobs per year citywide = 60k
Lets say the average pay of jobs eliminated per year = 62k
And lets say the average pay of new jobs created in the city per year is 70k

This means the positive difference 70k - 62k is growing year after year. Hence D is supporting the conclusion - "the average paycheck in this city has been getting steadily bigger."

Another vital assumption is the population group - employed and unemployed is NOT varying much. But since my job is not to weaken the argument, I won't attack this assumption. D is alright.

The answer here is most definitely not C; it's D.

The argument in the passage isn't airtight. Sure, we know that each year jobs are added with 'above average' salaries. But if the overall average salary has been trending downward (either because high-paying jobs were eliminated, or because wages were being cut at existing jobs) the newly added jobs might not be enough to ensure that 'the average paycheck in this city has been getting steadily bigger.' D at least addresses one of those concerns: the jobs that have been eliminated were not especially highly paid.

C is completely irrelevant; it's definitely not the right answer.
