What questions do adverbial phrases ask and what do adjectival phrases ask

An adverbial phrase is a group of words that refines the importance of an action word, adjective, or adverb. Second, an adjectival phrase is a phrase that alters or describes a noun or pronoun.

Explanation:

Prepositional phrases, infinitive phrases can go about as verb-modifying adverbial phrases in the event that they alter an action word, qualifier, or modifier. An adjective prepositional phrase will come directly after the thing or pronoun that it adjusts.

The adjective can start the expression (for example enamored with steak), finish up the expression (for example happy), or show up in an average position (for example very irritated about it).  

Adverbial phrases expressions don't contain a subject and an action word. At the point when these components are available, the gathering of words is viewed as a verb-modifying proviso. The accompanying sentence is a model: "When the show closes, we're eating."

the correct answer would be:  

a. adverb phrase
