Question

My hand slid under the mattress,searching for the notes (pick out the participle and state it’s function)

Answer 1

Answer:

there should be a space after the comma connected to mattress

in all seriousness i believe I've found the correct answer below

Explanation:

Both of these terms are participles but i believe it may be asking for the one that modifies a word so the answer then would have to be slid as it modifies hand but then could searching modify notes.

There are two reasons i would pick slid if its only a one answer question,

a. slid is directly connected to hand

b. slid does not use an -ing making it a past participle.

I'm quite sure the question is about past participles so slid modifies his hand in the sentence and provides context for how his hand got under the mattress...
