Select the most appropriate option to fill in blank number 3.
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. While.
- While is used to connect a subordinate clause to the main one.
- Here are two actions,
- (i) a study finding out some evidence but
- (ii) the size of the study making it difficult to conclude something concrete, are two different actions happening simultaneously.
"While" thus becomes the most appropriate when connecting two clauses with simultaneous actions.
