Help the worried owner track down Mr. Whiskers' hiding spots by selecting the best word for each gap.
First, I searched for my cat _________________________ the basement, but it was too dark. Then, my neighbor said she saw a cat sleeping _________________________ the third-floor balcony. Finally, I found the silly guy waiting for me _________________________ the front door of our apartment building!
The correct answers are in, on, and at.
We use in for enclosed spaces, rooms, and levels inside a building (like in the basement).
We use on for floors, roofs, and open structures attached to a building (like on the balcony or on the third floor).
We use at for a specific point or location in or around a building (like at the front door or at the entrance).
