Q1  15
Q1 15

Question 1: Mount Everest is ___ mountain in the world.

Question 1 options
'the tallest' is correct because one-syllable adjectives form the superlative by adding -est, and the definite article 'the' is always used before a superlative adjective. 'most tall' incorrectly uses 'most' with a one-syllable adjective, 'taller' is a comparative form, and 'tallest' without 'the' is missing the required article.
Q2 15

Question 2: This is ___ test I have ever taken in my life.

Question 2 options
'the hardest' is correct because one-syllable adjectives form the superlative with -est, and 'the' must precede the superlative. 'the most hard' incorrectly uses 'most' with a one-syllable adjective, 'the harder' is a comparative form, and 'the hardest more' is not a valid superlative structure.
Q3 15

Question 3: To form the superlative of adjectives with three or more syllables, you add -est to the end of the adjective.

Question 3 options
False because adjectives with three or more syllables form the superlative by using 'most' or 'least' before the adjective (e.g., 'most expensive', 'least interesting'). The -est suffix is used only with one-syllable adjectives and some two-syllable adjectives.
Q4 15

Question 4: When do we use a superlative adjective instead of a comparative adjective?

Question 4 options
Superlative adjectives are used when comparing three or more items and expressing the highest or lowest degree of a quality. Comparatives are used only when comparing exactly two items.
Q5 15

Question 5: Arrange the words to make a correct sentence:

Question 5 options
  • the smallest
  • This is
  • room
  • in the house

Drag items or use arrows to arrange them in the correct order.

The correct order is 'This is the smallest room in the house' because the superlative 'the smallest' (one-syllable adjective + -est) must follow the linking verb 'is', and the location phrase 'in the house' follows the noun.
Q6 15

Question 6: Which sentence uses the superlative adjective correctly?

Question 6 options
'She is the most intelligent student in the class' is correct because adjectives with three or more syllables form the superlative with 'most'. 'She is the intelligenter student' uses the wrong comparative ending, 'She is the intelligentest student' incorrectly adds -est to a long adjective, and 'She is most intelligently student' misuses an adverb form.
Q7 15

Question 7: Customer: "I want to buy a new phone. Which one should I choose?" Shop assistant: "This model is ___ phone we sell. Many customers love it!"

Question 7 options
'the most popular' is correct because 'popular' is a three-syllable adjective and requires 'most' to form the superlative, and 'the' must precede the superlative form in this context. 'the popularest' incorrectly adds -est to a long adjective, 'most popularer' mixes superlative and comparative forms, and 'the more popular' is a comparative, not a superlative.
Q8 15

Question 8: Which sentence correctly uses a superlative adjective (not a comparative adjective)?

Question 8 options
'This is the newest phone in the shop' correctly uses the superlative 'the newest' to express the extreme degree among all phones in the shop. The other options use comparative forms ('newer than', 'more new than', 'newer of') which compare only two items rather than expressing the highest degree among three or more.
Q9 15

Question 9: Put the words in the correct order:

Question 9 options
  • day
  • the happiest
  • of my life
  • Today was

Drag items or use arrows to arrange them in the correct order.

The correct order is 'Today was the happiest day of my life' because 'happiest' is formed by changing -y to -i and adding -est, it must be preceded by 'the', and the phrase 'of my life' follows the noun to show the group being compared.
Q10 15

Question 10: The weather was terrible last week. Monday was the ___ day of the whole week.

Question 10 options
'worst' is correct because 'bad' is an irregular adjective whose superlative form is 'worst' — it does not follow the standard -est or 'most' rules. 'baddest' incorrectly applies the regular -est rule, 'most bad' incorrectly uses 'most' with this irregular adjective, and 'most worst' doubles the superlative marker.
Q11 15

Question 11: A student writes: 'July is the most hot month of the year.' Which statement about this sentence is true?

Question 11 options
The sentence is incorrect because 'hot' is a one-syllable adjective and must form its superlative with -est (the hottest), not with 'most'. Additionally, when a one-syllable adjective ends in consonant-vowel-consonant, the final consonant is doubled before adding -est.
Q12 15

Question 12: Rewrite using the superlative: 'No river in the world is longer than the Nile.' → The Nile is ___ river in the world.

Question 12 options
'the longest' is correct because 'long' is a one-syllable adjective that forms its superlative by adding -est, and the sentence requires the superlative form with 'the' to express the highest degree. 'the most long' incorrectly uses 'most' with a one-syllable adjective, 'the longer' is a comparative form, and 'the most longest' doubles the superlative marker.
Q13 15

Question 13: Match each sentence to the correct grammar label.

Question 13 options
This box is the biggest one in the warehouse.
Anna is the friendliest person in our group.
That was the most difficult exam I have taken.
She is the best player on the team.
Three-syllable adjective superlative (most + adjective)
Irregular superlative adjective
Two-syllable adjective ending in -y (change y to i + -est)
One-syllable adjective superlative (double final consonant + -est)

Select an item on the left, then tap its match on the right.

Superlative adjectives are formed differently depending on the number of syllables and the adjective type: one-syllable adjectives take -est, two-syllable adjectives ending in -y change to -iest, adjectives with three or more syllables use 'most', and irregular adjectives have unique forms.
Q14 15

Question 14: Two-syllable adjectives that end in -y always form the superlative by adding 'most' before the adjective.

Question 14 options
False because two-syllable adjectives ending in -y form the superlative by changing the -y to -i and adding -est (e.g., happy → happiest, crazy → craziest). Using 'most' before these adjectives is incorrect.
Q15 15

Question 15: A writer wants to say that a city has very low crime compared to all other cities in the country. Which sentence best expresses this meaning using a superlative?

Question 15 options
'This city has the least crime of any city in the country' correctly uses 'the least' as the superlative of 'little' to express the lowest degree among all cities. The other options either use comparatives, incorrectly form the superlative, or change the intended meaning.
