Question

In which sentence does the introductory word to the noun clause function as an adverb?

Answer 1

The answer to this would be option B. This is the only sentence that uses an introductory word to the noun clause that is used as an adverb. If you will notice, the noun clause here is "when the flagpole was painted". And this noun clause modifies the verb "know". Hope this helps.

Answer 2

Answer:

B) I do not know when the flagpole was painted is the correct answer.

Explanation:

A noun clause is a dependent clause that has the role of a noun. To indicate these clauses, there are several words such as that, whatever, how, when, among others. An adverb is a word that describes an adjective, a verb, or even other adverbs. There are different types, like frequency adverbs, adverbs of manner, and adverbs of time.

In the second option, the introductory word to the noun clause is when, but it also acts as an adverb (even if it is unknown or not accurate)because it modifies the noun clause, which is "the flagpole was painted".
