Confused about the intellectual curiosity question

I know this sounds a little dumb but just for clarification, is this question asking an actual list (i.e. listed with bullet points)? If so, should I at least have a small description for each activity?

EDIT: Also, would things like casual reading (of books, educational websites, etc.) count as an “intellectual activity”?

Please indicate how this question is being posed?

Google “Harvard admissions what counts as an intellectual activity” and you’ll get several links to blogs that will answer the question, including this one

Other examples of intellectual activities: Playing chess, doing the NY Times crossword puzzle, studying a new language on your own, reading for fun, being part of a book club etc.

But understand this isn’t just idle curiosity on their part.
