Also, please indicate why your answer is correct for knowledge of written compound words.
Much appreciated.

Answer 1

That would be answer B, because "Thirty One" needs to have a dash, and "Quickly" is an adjective for running, which does not make is a compound word. "Moment" and "Decision" are two completely different words. Most words that con joined or described with "self" are going to have a dash to join them.
