QUESTION 22-26: GRAMMAR IN USE
Mini Heroes Challenge · 5 lessons
______ just bought a brand-new phone and won’t stop talking about it?
Correct answer: Who
The sentence needs a question word that asks about a person. "Who" is the only interrogative pronoun that identifies people. The blank is asking "*Which person* just bought a phone?"
Why the others are wrong:
- When asks about time (not applicable here)
- Why asks about reason or cause (not applicable here)
- What asks about things or objects (not about people)
The mermaids, known for their enchanting voices, ______ to sing under the moonlight sky.
Why A is correct:
"The mermaids" is a plural noun, so it needs the plural verb form "like" (not the singular "likes").
Why the others are wrong:
- B (likes): This is singular and doesn't match the plural subject "mermaids."
- C (liked): This is past tense, but the sentence uses present tense ("known," "are") so it should stay consistent.
- D (liking): This is a gerund/participle form, not a proper verb for this sentence structure.
To ensure I don’t miss my flight, I ______ leaving for the airport earlier than usual.
Correct answer: am
The subject "I" is first-person singular, so it needs the first-person singular verb form "am." This matches the subject-verb agreement rule.
Why the others are wrong:
- is → Used with third-person singular (he, she, it), not "I"
- are → Used with second-person (you) or plural subjects (we, they), not "I"
- has → This is a different verb (have/has) and doesn't fit the sentence structure; you need a form of "to be"
Marissa spends her weekends restoring damaged forests by planting trees. ______ finds joy in giving back to nature.
Correct answer: She
- Marissa is a female name, so the feminine pronoun "she" is correct.
Why the others are wrong:
- He — masculine pronoun; doesn't match Marissa's gender
- They — plural pronoun; Marissa is one person, not multiple people
- It — used for objects/things, not people
Zahra and Mikael, armed with flashlights and backpacks, ______ exploring a hidden cave in search of ancient artifacts.
Correct answer: A (are)
"Zahra and Mikael" is a plural subject (two people), so it needs a plural verb. "Are" is the present-tense plural form of "to be."
Why the others are wrong:
- B (is) – This is singular and doesn't match two people.
- C (was) – This is past tense, but the sentence uses present-tense "armed" and "exploring."
- D (were) – This is past tense plural; it doesn't fit the present-tense context.
