I am finding it pretty difficult to comprehend RCs based on Philosophy and Art especially. It hampers my understanding of the main points of the passage too. Any tips/resources to help me with the same.

Hi Deepesh Sharma,
We suggest you to read articles based on Philisophy and Art. For both these subjects, Aeon is a good source; for a more in-depth understanding of Philosophy, there's the Stanford Encyclopedia of Philosophy. Smithsonian magazine has a good collection of articles on Art.
Hope this helps!
