Editorial: Companies worldwide have started adopting MAT (Management Aptitude Test), a decade-old standardized online-based aptitude entrance test administered centrally by CGI (Confederation of Global Industries) all round the year to screen in the most eligible candidates for their respective interviews. Latest statistics released by CGI show that the average error rate, a statistical figure to assess the difficulty level of a question and determined only after the number of respondents reaches at least thousand, of ten toughest questions in a sample group of MAT tests conducted within any pre-defined time interval not earlier than three years ago has never exceeded 70%. A particular question recently introduced by CGI in MAT was, however, found to have an error rate of more than 80%, attempted by approximately 5000 candidates worldwide. Hence, this question could be considered among the toughest of the questions to have appeared on the MAT. But, some respondents contend that the new question was indeed so tough need not be true as it is also quite likely that the official answer to the question itself is wrong.
Which of the following, if true, would most help to arbitrate the contention presented in the argument?
A. 95% of the respondents who got the question right scored at least 99 percentile on the MAT.
B. Statistics released by CGI have revealed that for any time interval put under consideration since the last ten years, the difference between the number of respondents per thousand answering the ten toughest questions correctly and number of those answering them wrong has varied between 200 and 650.
C. The average error rate of the ten toughest questions in any time interval, not later than three years ago, was approximately 74%.
D. As per latest records available by the CGI, most of the all-time toughest questions on MAT put to test, the error rate of which exceeded 80% but not 85%, have been certified as perfectly valid questions with correct official answers by more than one independent auditor.
E. Studies by certified psychometricians indicate that a question in any online-based aptitude entrance test cannot achieve a maximum error rate not lower than 80%, even after allowing for a maximum grace variation in error rate up to 5%.

A great question...Rack your brains!!
