Detective Grammar needs your help! These apostrophe imposters are causing confusion everywhere. Select ALL the sentences that correctly use "it's/its" and "who's/whose."
The correct answers are It's been a long day at work, Whose umbrella is this?, The company changed its logo last year, and Who's coming to the party tonight.
"It's" = it is or it has (contraction), "its" = possessive (belonging to it). "Who's" = who is or who has (contraction), "whose" = possessive (belonging to whom). In "The dog wagged it's tail," the possessive "its" is needed. In "Who's turn is it," the possessive "whose" is needed.
