Xavier Aptitude Test 2015 Paper

(b) Ranu is an ordinary sportsperson. In the last two university sprint events, her performances in the heats were pathetic. So statements that show her as a great sportsperson will weaken the argument. So (a) is wrong as it does not show Ranu to be a great sportsperson. The rest of the 4 options show that he is a good/ great sportsperson, so the one which will show her to be the greatest sportsperson would weaken the argument the most.
(d) and (e) show her to be a college level sportsperson, so they are wrong.
Among (b) and (c), (b) is the answer as it shows her to be a national shot-put champion, whereas (c) does not mention any such level of hers.
