Choose the correct adverb to fill in the blank:
The teacher explained the concept __________ to ensure that all the students understood.
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → clearly
An adverb is a word that tells how, when, where or how much something happens. It can also describe an adjective or another adverb, for example she sings sweetly, very hot.
Complete sentence: The teacher explained the concept clearly to ensure that all the students understood. The blank comes after the verb “explained” and its object “the concept”. It must tell how the teacher explained, so it needs an adverb of manner.
| Option | What it tells | Example |
|---|---|---|
| (1) clear | an adjective: it describes a noun, such as clear water or a clear answer | The sky is clear after the rain. |
| (2) clearly (answer) | the adverb (clear + ly): in a way that is easy to understand | Please write your roll number clearly on the answer sheet. |
| (3) clearness | a noun: it names the quality of being clear | We liked the clearness of the lake water. |
| (4) clearing | the -ing form of the verb “clear”, which means to remove things from a place | The workers are clearing the snow from the road. |
