Question

Select a suitable adverb clause to complete the sentence:
, I enjoyed spending time at the beach.

• A. It was a sunny day
• B. Even though I don't like sand
• C. While leaving from there
• D. None of the above

Answer 1

The correct option is B Even though I don't like sand

An adverb clause is a group of words containing a subject and a verb, and it functions as an adverb, by modifying an adjective, verb or an adverb. Adverb clauses generally begin with a subordinate conjunction (since, because, while, etc.).
Option B is correct because it is an adverb clause of concession or contrast, 'even though' is a subordinate conjunction. It refers to two ideas that contrast each other: "I don't like sand", "enjoyed spending time at the beach".
Option A is incorrect because it is a complete sentence that has no connection to the given clause "I enjoyed...beach"; an adverb clause must be subordinate/dependent.
Option C is incorrect because it is a phrase, there is no subject nor verb.
Option D is incorrect because the answer lies in B.
