Need Strategy help on Assumption Quesiton

by dippradhan » Wed Jan 05, 2011 4:13 pm
Correctly measuring the productivity of service workers is complex. Consider, for example, postal workers: they
are often said to be more productive if more letters are delivered per postal worker. But is this really true? What
if more letters are lost or delayed per worker at the same time that more are delivered?
The objection implied above to the productivity measure described is based on doubts about the truth of which
of the following statements?
(A) Postal workers are representative of service workers in general.
(B) The delivery of letters is the primary activity of the postal service.
(C) Productivity should be ascribed to categories of workers, not to individuals.
(D) The quality of services rendered can appropriately be ignored in computing productivity.
(E) The number of letters delivered is relevant to measuring the productivity of postal workers.

I used below strategy to identify the solution. I choose E. Could someone please explain the correct answer? E is not the correct answer.
Strategy #1 : an assumption should fill the gap between the evidence and the conclusion
Strategy #2 : Negation Test. Because the assumption is necessary for the conclusion to stand, negating the assumption will break the conclusion apart

1. Measuring productivity is complex
2 Postal workers are said to be more productive if more letters are delivered
3. What if as more letters are delivered more are lost?

The author is saying that there should be more to measuring productivity than just pure output because other areas could be negatively effected. It should not be so simple to measure letters delivered and only have that measure productivity.

A. Incorrect. The author would agree with this.

B. Incorrect. He is not questioning whether or not this is the primary activity. He is questioning whether it is the sole measure by which to measure productivity

C. Incorrect. Never does he mention categories vs individuals

D. Correct. If postal workers productivity is just based on how much they deliver with no consideration for other parts of the job then that is the only part of measuring production that matters. This must be true for statement 1 to be true, which is the statement that the author objects to. He does not believe that quality can be ignored. If postal workers are losing more mail in an attempt to deliver more mail then they are not necessarily productive.

E. Incorrect. This is the one that is designed to trick you. Its easy to assume that he is saying the number delivered is not important, but carefully re-read the passage. He never says that its not relevant. He just says it should not be the only factor. Remember the initial statement that measuring productivity is complex. It means many things should go into it.

@dippradhan, the explanations about this CR entry are available with multiple BTG posts, if you will use the search tool in the right upper corner of menu. If you wish to kill CRs try not to use the notions from GMAT prep books which you just described in your post. It seems that you did very good homework by reading and memorizing all strategies and tips from CR books but still unable to apply them thoroughly. Ask yourself, beforehand, 'what is the stated reason for conclusion made in the passage?' (I'm not supplying you with the additional CR tips!) After you learn - actually read - the stated reason of author, ask yourself 'what could be additional reason for this conclusion?' Then ask yourself some more questions: 'what if the conclusion made is intentionally or unintentionally (as claimed by GMAT) linked to the reason(s) stated in the passage?' 'in case there are other possible reasons for this conclusion to be valid or not valid, what are these reasons?'

Making the long list short, you would need to become the reason skilled for solving CR entries. The more you practice, the better skilled you should become.
