Question

I (knew/had known) exactly what to do because i (did/had done) it many time

Answer 1

I KNEW exactly what to do because I HAD DONE it many times.

Answer 2

Both "knew" and "had done" are correct in this sentence, but the choice between "did" and "had known" depends on the context and the specific meaning you want to convey. Here are both options:

1. "I knew exactly what to do because I had done it many times."

   • This sentence uses the past perfect tense ("had done") to indicate that your knowledge of what to do was based on prior experience. It emphasizes that your knowledge was established before a certain point in the past.

2. "I knew exactly what to do because I did it many times."

   • This sentence uses the simple past tense ("did") to convey that you knew what to do based on your past experiences, without emphasizing the sequence of events as strongly as the first option.

Both sentences are grammatically correct, so you can choose the one that best fits the nuance you want to convey.
