Just a note: -A shows some invisible characters like $ at the end of the line, it was not necessary here.

You would need to use an option here to show the line before the line containing cure. Hint: check out https://man7.org/linux/man-pages/man1/grep.1.html (-B)

Almost, you could also just print the file names. Check out --files-with-matches here: https://man7.org/linux/man-pages/man1/grep.1.html

This doesn't add a space after the comma in the line 11, could you please double check?

Almost! There should be no quotes, I am getting this:
$ jq '.[] | "\(.name) \(.scores | length)"' scores.json
"Ahmed 3"
"Basia 3"
"Mehmet 3"
"Leila 1"
"Piotr 5"
"Chandra 2"
