Fill in the blank with the most appropriate determiner:
Since the solar panels went up on the roof, our school uses ______ electricity from the grid than it did last year.
Answer & explanation
Correct answer: option 3
The correct answer is Option (3) → less
Complete sentence: Since the solar panels went up on the roof, our school uses less electricity from the grid than it did last year. “Electricity” cannot be counted, and “than it did last year” compares two amounts.
| Option | Meaning and use | Example |
|---|---|---|
| (1) fewer | a smaller number, with countable plural nouns | There are fewer students in the library during the holidays. |
| (2) many | a large number, with countable plural nouns | Many birds come to Chilika Lake in winter. |
| (3) less (answer) | a smaller amount, with uncountable nouns (things we cannot count) | Our new fridge uses less power than the old one. |
| (4) much | a large amount; on its own it cannot compare two things with “than” | We did not have much homework today. |
