Question

In which sentence does the adverb clause modify an adverb?

A.) The Amazon River has been said to be longer than the Nile River.

B.) Madagascar, where 90% of the known species of lemur live, is the world’s fourth largest island.

C.) Although Denmark is located on a peninsula, the country also includes more than 400 islands.

Answer 1

B I think not for sure

Answer 2

Answer: C

Explanation: The infinitive clause "to be longer than the Nile River" in option A acts as a compliment, and the clause "where 90% of the known species of lemur live" in option B functions as an adjective modifying the noun Madagascar. "Although Denmark is located on a peninsula" is an adverb clause that modifies the adverb "also."
