Answer Explanations

Question 1 Explanation

The correct answer is hasn’t finished. We use the present perfect with “yet” in negative sentences to show that something has not happened up to now. The sentence focuses on the present situation, because the homework is still not finished at the moment of speaking.

Question 2 Explanation

The correct answer is met. We use the past simple for a completed action that happened during another longer action in the past. “Was walking” gives the background action, and “met” shows the shorter event that happened at a specific moment.

Question 3 Explanation

The correct answer is will arrive. This is a first conditional sentence because it describes a real possible future result. The “if” clause uses the present simple, and the main clause uses “will” plus the base verb.

Question 4 Explanation

The correct answer is must. We use “must” to express strong obligation or a rule. A library is a place where silence is normally required, so the sentence expresses something that people are expected to do.

Question 5 Explanation

The correct answer is few. We use “few” with plural countable nouns to mean a small number. “Tickets” is plural and countable, and the word “only” supports the idea that not many tickets remain.

Question 6 Explanation

The correct answer is a. Although “university” begins with the letter “u,” it starts with the sound /juː/, which is a consonant-like sound. Because article choice depends on pronunciation, not only spelling, the correct article is “a.”

Question 7 Explanation

The correct answer is where. We use “where” in relative clauses when we refer to a place. In this sentence, “the restaurant” is the place connected to the action of having dinner.

Question 8 Explanation

The correct answer is of. The adjective “proud” is usually followed by the preposition “of.” The sentence means that her son’s success gives her a feeling of pride.

Question 9 Explanation

The correct answer is talking. After the verb “avoid,” we normally use a gerund form. A gerund is the -ing form of a verb used like a noun, so “talking” is grammatically correct here.

Question 10 Explanation

The correct answer is to see. After the verb “hope,” we normally use the infinitive form with “to.” The sentence expresses a wish or expectation about a future meeting.

Question 11 Explanation

The correct answer is safer. We use a comparative adjective when we compare two things. In this sentence, one road is compared with the old road, so the comparative form is needed.

Question 12 Explanation

The correct answer is is cleaned. This sentence uses the passive voice because the focus is on the room, not on the person who cleans it. The phrase “every morning” shows a regular action, so the present simple passive is correct.

Question 13 Explanation

The correct answer is seen. In the present perfect, we use “have” or “has” plus the past participle form of the verb. The past participle of “see” is “seen,” so it is required after “have never.”

Question 14 Explanation

The correct answer is clearly. We use an adverb to describe how someone does an action. Since “speak” is a verb, the adverb “clearly” is needed instead of the adjective “clear.”

Question 15 Explanation

The correct answer is to. We use “to” plus the base verb to express purpose. In this sentence, the purpose of going to the library was studying for the exam.

Question 16 Explanation

The correct answer is much. We use “much” with uncountable nouns, especially in negative sentences and questions. “Time” is uncountable in this sentence, so “much” is the correct quantifier.

Question 17 Explanation

The correct answer is was. The sentence describes a past state at the time of the phone call. Since the action happened in the past, the past form of “be” is needed.

Question 18 Explanation

The correct answer is about. The adjective “worried” is commonly followed by the preposition “about.” The sentence means that the final exam is the cause of the speaker’s worry.

Question 19 Explanation

The correct answer is come. In the present perfect with “has just,” we use the past participle form of the verb. The verb “come” has the same base form and past participle form, so “come” is correct here.

Question 20 Explanation

The correct answer is drinks. We use the present simple for habits and routines. The word “usually” shows a regular action, and the subject “my mother” requires the third-person singular form.

Question 21 Explanation

The correct answer is went. We use the past simple for completed actions at a specific finished time in the past. The phrase “two days ago” clearly shows that the action happened in the past.

Question 22 Explanation

The correct answer is should. We use “should” to give advice or make a recommendation. The sentence suggests seeing a doctor as the sensible action if the pain continues.

Question 23 Explanation

The correct answer is who. We use “who” in relative clauses when we refer to people. In this sentence, “the woman” is a person, and the relative clause tells us more about her.

Question 24 Explanation

The correct answer is seeing. After “look forward to,” we use a noun or a gerund form. In this structure, “to” is a preposition, not part of an infinitive, so the -ing form is required.

Question 25 Explanation

The correct answer is for. We use “for” with a period of time, such as three months, two years, or several days. The sentence describes the length of time they have worked on the project.

Question 26 Explanation

The correct answer is the. We use “the” before superlative adjectives such as “worst,” “best,” and “most important.” In this sentence, one day is identified as the worst day of the whole holiday.

Question 27 Explanation

The correct answer is why. We use “why” when we are talking about a reason. The sentence is an indirect question, so the word order is “why she left early,” not “why did she leave early.”

Question 28 Explanation

The correct answer is because. We use “because” to give the reason for something. In this sentence, waking up late explains why he missed the bus.

Question 29 Explanation

The correct answer is little. We use “little” with uncountable nouns to mean not much. “Milk” is uncountable, and the sentence means that only a small amount of milk remains in the bottle.

Question 30 Explanation

The correct answer is would learn. This is a second conditional sentence because it describes an unreal or unlikely present situation. The “if” clause uses the past simple, and the main clause uses “would” plus the base verb.
