She placed the book __ the shelf.

She placed the book __ the shelf.

• A. Under
• B. Beside
• C. On
• D. Above

Answer: (C)

The idea being tested is choosing the preposition that shows where something is in relation to a surface. When you place a book on a shelf, it sits on the shelf’s top surface, in contact with it. That’s why the word on fits best here. Under would place the book below the shelf, not on it. Beside means next to the shelf rather than on its surface. Above suggests being higher than the shelf, not resting on it. So on is the natural choice for a book resting on the shelf.
