>>59632696Hold on, I realize I could've clarified further for a more comprehensive view on the subject.
"Whose" refers to the owner of possessions, either physical(shoes, computer, book) or metaphysical(whose opinion, turn, actions).
"Who's" refers to gathering more information concerning a person themselves.
For a more reliable method, when you're not sure which one to use, try typing the sentence with "who is" or "who has", and if it sounds right, it's "who's", and if it sounds wrong, it's probably "whose".
