b. Jenny was the largest elephant in the circus.
c. I hesitated a moment, but her smile gave me courage.

Answer 1

"a. After the rain ended, the sky became blue" would contain an independent clause and a dependent clause, which makes it a complex sentence, since the latter half wouldn't be the same without the former half.
