What must google do to keep the competitors AT BAY?
I know a prepositional phrase can act as an adverb by modifying the finite verb in the sentence, or act as an adjective by modifying the noun/pronoun just before it. My question is about how I know prepositional phrases used are modifying verb or noun/pronoun before it. I'm confused that In the sentence above, Whether "AT BAY" modify the verb DO or noun The COMPETITORS. For example, I like the books on the table. Here *on the table * have modified the table not like. how could I be able to know it is acting as an adjective or an advern. Thank you.
