3. We heard the news that his team had won.

4. The idea of helping poor people in underdeveloped country was normal.

5. He had only one aim, to earn a lot of money.

6. We Koreans live on rice.

(Are they all grammatical? They are example sentences containing apposition, right?)

Answer 1

2 and 6 have appositives in them.

In 2, the word is "compiles," not "complies."

All other sentences are correct, but don't have appositives in them.
