Question

Fill in the blank with a suitable adverb clause:
You work harder . Yet, she got promoted.

• A. in the office
• B. for this job
• C. than she does
• D. None of the above

Answer 1

The correct option is C than she does

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 C is correct because it is an adverb clause of comparison ('than' is an adverb of comparison).
Option A is incorrect because it is a phrase, not a clause.
Similarly, option B is incorrect because it is a phrase, not a clause.
Option D is incorrect because the answer lies in C.
