Select the most appropriate option to fill in blank number 2.
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. adequate.
- The sentence is talking about creating awareness among people of all ages to control air pollution.
- In this context, the word "adequate" implies that a sufficient level of awareness needs to be created.
- The other options, like "quite," "much," or "few," do not convey the same sense of sufficiency or appropriateness needed in this context.
Hence, the correct option would be adequate.
