I think it's A. It is definally not the climax as this happens when Beowulf kills the monster. It's not the resolution either as it is the first part of the text. Also, exposition seems a little unrelated.
“About Mars” is the Adjective Phrase.
Adjective phrase describes “what kind of which ones”
So for example here
“After school, I looked for books about Mars.”
“About Mars” describes the kind of books so that makes it an Adjective phrase.

Set up a proportion
12/14 = x/21
They have already won 12 out of 14 games.
What you are asking is how many will the win (call that number x) if they play 21 games.
Solution
12/14 = x/21 Cross multiply
14* x = 12*21 Combine the right
14x = 252 Divide both sides by 14
14x/14 = 252/14 Do the division
x = 18
They should win 18 games.
