Please tell me the reason why she got angry.

I don't know why they are so steamed off at us.

He lied to me. That is why I am angry with him.

I don't know why, but he seems to have it in for me.

He had no idea why his wife left him.

He gave no explanation why he had been absent.

He wondered why they looked excited and tried to get their attention.

I began to understand the reason why he hated me.

I see no reason why he doesn't relate to the firm.

I don't know the reason why he will not go on to college.
