SOF, this correction has been pointed out many times, the earliest comment being from 3 years ago, why has it not been corrected yet. The answer is obviously A Reliable Pupil and not B Pupils as the latter has not even been mentioned in the given paragraph. This should be corrected immediately as it is confusing many of us. Furthermore, question has been repeated twice in this mock test. Question number 27,the repetition of the question has the correct solution marked as A. How can the same question have different answers. Please do resolve this. Thankyou.
