Step 1: Identify the confirmed outcome for exercise.
The passage clearly states that listening to music during exercise improves performance and reduces discomfort. Hence, the positive effect of music on physical exercise is well established.
Step 2: Analyze the findings related to learning.
The research on listening to music while studying yielded inconclusive results. Specifically, students who required external stimulation performed worse, whereas students who did not require such stimulation benefited from music.
Step 3: Draw the correct inference.
Since music benefits only a subset of students (those who do not need external stimulation), it cannot be said to have a universally positive effect on learning. The effect is conditional and applies only to some students.
Step 4: Evaluate the options.
Option (C) accurately combines both conclusions: a clear positive effect on exercise and a selective positive effect on learning. The other options either overgeneralize or misrepresent the findings.
% Final Conclusion
The correct inference from the passage is that music clearly improves exercise performance, while its effect on learning is positive only for some students.

I spent 32 years in Information Technology out of which I was a Chief Executive Officer or MDorthe software head for 23 years for large global multinational software companies with thousands of software professionals worldwide and 6 offices in the US, 3 in Europe, 1 in Japan and 1 in Australia. I had to travel all over the globe around 150 times for business. During this period, I had also written 4 books with 500-700 pages each on Information Technology published by Tata McGraw-Hill and then translated into Chinese for global distribution.
I learnt a lot of things when I was running these large companies. The first one was the importance of team work. In today’s world, nothing is possible without team work. You cannot be successful if you are a loner and an egoistic person. Secondly, you need to lead from the front by setting a good example in front of your staff. Third was that you need to treat your subordinates and your colleagues as friends. In my career, I made a few mistakes, but learnt a lot about motivation, being a good listener, target setting and the art of delegation which forms such an important part of today’s management.
After working for all these software companies for so many years, I wanted to retire from my line of work and write on various subjects concerning human life and existence. Therefore, I gave up two offers of around 3 crore rupees per annum to become a writer. This is how my second innings as a writer in Marathi began.
After this, I have written about 34 books in Marathi. Most of them have become bestsellers with tens of thousands of copies sold for each. However it is not sales or the money that is important to me as much as the fact that these books have brought about very good changes in the lives of thousands of readers.
