Question

Choose a suitable adverb clause to complete the sentence:
We will go to the mountain top .

• A. even if it starts snowing
• B. still it starts snowing
• C. however it starts snowing
• D. none of the above

Answer 1

The correct option is A even if it starts snowing

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 A is correct because it is an adverb clause of concession or contrast, 'even if' is a subordinate conjunction that refers to two ideas that contrast each other: "go to the mountain top", "starts snowing".
Option B is incorrect because it is a coordinate/independent clause, 'still' is an adversative conjunction whereas an adverb clause is not independent. (Generally, adverb clauses are subordinate/dependent clauses, they form a part of a complex sentence.)
Option C is incorrect because even though it is a subordinate clause, it is not relevant in meaning here, 'however' means 'regardless of how', whereas 'even if' means 'no matter what'. The latter provides complete meaning to the sentence.
Option D is incorrect because the answer lies in A.
