Question

complete the sentence with the best subject.
outside my window,
__________ gently falls on the oak trees.
warm raindrops
the soft white snow

Explanation:

We need a subject that agrees grammatically with the verb "falls" (singular/collective singular) and makes logical sense. "Warm raindrops" is plural, which would require the verb "fall" instead of "falls". "The soft white snow" is a singular collective noun that matches the singular verb "falls" and logically can fall gently on trees.

Answer:

the soft white snow
