Question

Which sentence uses a definite article?   A. The children played in the pool all day long.   B. A duck flew into our pool.   C. I enjoy swimming laps in a pool.

Answer 1

I would say answer A. It fits the best in my opinion.

Answer 2

The definite article is the word 'the'. It is used before a noun to specify it was something previously considered. So, A) The children played in the pool all day long makes the most sense to me.
