Municipal officials originally estimated that it would be six months before municipal road crews could complete repaving a stretch of road. The officials presumed that private contractors could not finish any sooner. However, when the job was assigned to a private contractor, it was completed in just 28 days.
Which one of the following, if true, does most to resolve the discrepancy between the time estimated for completion of the repaving job and the actual time taken by the private contractor?
(A) Road repaving work can only be done in the summer months of June, July and August.
(B) The labor union contract for road crews employed by both municipal agencies and private contractors stipulates that employees can work only eight hours a day, five day a week, before being paid overtime.
(C) Many road-crew workers for private contractors have previously worked for municipal road crews and vice versa.
(D) Private contractors typically assign 25 workers to each road-repaving job site whereas the number assigned to municipal road crews is usually 30.
(E) Municipal agencies must conduct a lengthy bidding process to procure supplies after repaving work is ordered and before they can actually start work, whereas private contractors can obtain supplies readily as needed.
So Private contractors had the work completed faster than estimated. So there must be something different with how private contractors conduct their work, lets see which option tell us, about how private and Municipal workers , conduct their work, then maybe we would know, how Municipal workers were able to finish it sooner.Lets see the options:
(A) Road repaving work can only be done in the summer months of June, July and August : This fact is applicable to both private and municipal workers hence does not show how Private contractors could have completed the work sooner.
INCORRECT.(B)The labor union contract for road crews employed by both municipal agencies and private contractors stipulates that employees can work only eight hours a day, five day a week, before being paid overtime : Also Applicable to both private and municipal workers hence does not show how Private contractors could have completed the work sooner.
INCORRECT.(C)Many road-crew workers for private contractors have previously worked for municipal road crews and vice versa :
Applicable to both private and municipal workers hence does not show how Private contractors could have completed the work sooner.
INCORRECT.(D)Private contractors typically assign 25 workers to each road-repaving job site whereas the number assigned to municipal road crews is usually 30 : If this is the case then Municipal workers should have taken lesser time because more of them are working at each site, so clearly this does not explain how private workers took lesser time.
INCORRECT.(E)Municipal agencies must conduct a lengthy bidding process to procure supplies after repaving work is ordered and before they can actually start work, whereas private contractors can obtain supplies readily as needed :This option highlights one major difference between how Private and Municipal workers conduct their work.This fact clearly explains how private contractors could have had the work completed in lesser time.
CORRECT.Ans- E.
Hope it's clear.
