Explanation:

- Nadia had an apple and a ________ for breakfast.

- Option 1: pear - A pear is a type of fruit. It's commonly eaten and would logically fit the context of someone having it for breakfast alongside an apple.

- Option 2: prier - A prier refers to a person who pries or is nosy, which doesn't make sense in the context of breakfast.

- Option 3: pair - A pair means two of something, which doesn't fit well as the second item of a breakfast.

- Option 4: pare - To pare means to trim or cut, typically used to describe peeling fruit, not eating.
