Statement: The crush at a district treasury in the last week of every month arises because pension papers of every department, which need no more than a stamp, must be presented at the one counter that also receives challans and counts cash. Which of the following courses of action follows from the statement?

The statement names the cause precisely: quick work is queued behind slow work at a single counter. Separating the two removes that cause and nothing else is needed. Refusing papers after three shortens the day rather than the queue and simply turns people away; asking pensioners to come in the last three days concentrates the very crush complained of; and sending every paper to the district town adds a journey for the pensioner while leaving the counter's mixed workload untouched.
