couldn't/wouldn't green/screen
The analogy is "wouldn't is to couldn't as green is to scruple." In both cases, the first word is replacing a contraction of two words with a single word, and the second word starts with "scr," "spr," "str," or "thr."
The analogy of whirlwind is to breeze as downpour is to a word starting with scr spr str or thr 'sprinkle' or 'shower' is the answer.
