Many organizations have been resorting to recruitment based upon performance at graduate/post-graduate level exams rather than conducting exams for the same purpose. Which of the following statements would strengthen the argument given in the above statement ?

A recent study shows no link of past performance with the performance in recruitment exams.

The graduate/post-graduate exams are considered to be severely deficient in training in job related environment.

Organisations which had undertaken recruitment on the basis of graduate/post graduate exams report a significant drop in the quality of the recruited employees.

Such policies would add to unemployment among students having below average performance in graduation or post-graduation.

Such policies could save time, money and resources of the organisation which are wasted in the conduct of recruitment examinations.
