Answer Explanations

Question 1 Explanation

The correct answer is narrower. The sentence compares two places: this street and the main road. When we compare two things, we need a comparative adjective. “Narrow” can take -er, so “narrower” is the correct form.

Question 2 Explanation

The correct answer is the smartest. The phrase “in her class” shows that one girl is compared with all the girls in the class. This means the sentence needs a superlative adjective. “Smart” is a short adjective, so we use “the” and add -est.

Question 3 Explanation

The correct answer is more difficult. The word “than” shows that the sentence compares two lessons. “Difficult” is a longer adjective, so we do not usually add -er. Instead, we use “more” before the adjective to make the comparative form.

Question 4 Explanation

The correct answer is the easiest. The phrase “in the exam” shows that one question is compared with all the questions in the exam. This requires a superlative form. “Easy” ends in consonant + “y,” so we change “y” to “i” and add -est.

Question 5 Explanation

The correct answer is more modern. The sentence compares the speaker’s new phone with the old phone. “Modern” is usually treated as a longer adjective in basic grammar, so the comparative form is made with “more.” The word “than” confirms that a comparative form is needed.

Question 6 Explanation

The correct answer is the fastest. The phrase “in the school” shows that one runner is compared with all the runners in the school. This means the sentence needs a superlative adjective. “Fast” is a short adjective, so we add -est and use “the.”

Question 7 Explanation

The correct answer is more comfortable. The sentence compares this chair with that chair. “Comfortable” is a longer adjective, so its comparative form is made with “more,” not with -er. The sentence means that one chair gives a higher level of comfort than the other.

Question 8 Explanation

The correct answer is worse. The sentence compares today’s weather with yesterday’s weather. “Bad” is an irregular adjective, so its comparative form is not “badder.” The correct comparative form is “worse.”

Question 9 Explanation

The correct answer is the largest. The phrase “in the city” shows that one park is compared with all the parks in the city. This requires a superlative form. “Large” ends in “e,” so we add only -st and use “the.”

Question 10 Explanation

The correct answer is lighter. The word “than” shows that two bags are being compared. “Light” is a short adjective, so we add -er to make the comparative form. The sentence means that one bag has less weight than the other.

Question 11 Explanation

The correct answer is more interesting. The sentence compares this story with the first story. “Interesting” is a longer adjective, so we use “more” to form the comparative. The word “than” clearly shows that a comparative adjective is needed.

Question 12 Explanation

The correct answer is the kindest. The phrase “I know” suggests that one person is being compared with all the people known by the speaker. This requires a superlative form. “Kind” is a short adjective, so the correct form is made with “the” and -est.

Question 13 Explanation

The correct answer is cheaper. The sentence compares the red car with the black car. “Cheap” is a short adjective, so we add -er to form the comparative. The word “than” confirms that the sentence needs a comparative form.

Question 14 Explanation

The correct answer is the quietest. The phrase “in the village” shows that one place is compared with all places in the village. This means a superlative adjective is required. “Quiet” can take -est, and superlatives usually need “the.”

Question 15 Explanation

The correct answer is better. The sentence compares her English now with her English last year. “Good” has an irregular comparative form, so we do not say “gooder.” The correct comparative form is “better.”
