Answer Explanations

Question 1 Explanation

The correct answer is have lost. We use the present perfect when a past action has a clear result in the present. In this sentence, the speaker lost the keys before now, and the present result is that the door cannot be opened. The exact time of losing the keys is not important, but the present consequence is important.

Question 2 Explanation

The correct answer is went. We use the past simple for a completed action that interrupted another longer action in the past. “Were having dinner” shows the background action, and “went out” shows the sudden event. This structure is common when one action happens in the middle of another action.

Question 3 Explanation

The correct answer is will get. This sentence is a first conditional because it talks about a real possible future result. The “if” clause uses the present simple, and the main clause uses “will” plus the base verb. The meaning is that regular study can realistically lead to better results.

Question 4 Explanation

The correct answer is must. We use “must” to express strong obligation or necessity. In this sentence, wearing a seat belt is required by law, so it is not optional. The sentence talks about a rule that drivers need to follow.

Question 5 Explanation

The correct answer is many. We use “many” with plural countable nouns. “Mistakes” is plural and countable because mistakes can be counted one by one. The sentence means that the report contains a large number of errors.

Question 6 Explanation

The correct answer is an. We use “an” before a singular countable noun when the next word begins with a vowel sound. “Umbrella” begins with a vowel sound, so “an” is correct. The sentence introduces one umbrella in a general way.

Question 7 Explanation

The correct answer is who. We use “who” in relative clauses when we refer to people. In this sentence, “the teacher” is a person, and the relative clause gives extra information about that person. The clause explains which teacher the speaker means.

Question 8 Explanation

The correct answer is of. The adjective “afraid” is commonly followed by the preposition “of.” The phrase “afraid of flying” means that flying makes him feel fear or anxiety. This is a fixed adjective-preposition combination that learners should remember.

Question 9 Explanation

The correct answer is working. After “don’t mind,” we usually use a gerund form. A gerund is the -ing form of a verb used like a noun. In this sentence, the speaker says that working late is acceptable if the work matters.

Question 10 Explanation

The correct answer is to call. After the verb “promise,” we normally use the infinitive form with “to.” The sentence means that she made a promise about a future action. Because the action happens after the promise, the infinitive structure is required.

Question 11 Explanation

The correct answer is larger. We use a comparative adjective when we compare two people, places, or things. In this sentence, the speaker compares one room with another room. Since “large” is a short adjective, the comparative form is made by adding “-er.”

Question 12 Explanation

The correct answer is are cleaned. This sentence uses the passive voice because the focus is on the windows, not on the person who cleans them. The phrase “every Friday” shows a regular action, so the present simple passive is needed. The structure is “are” plus the past participle.

Question 13 Explanation

The correct answer is been. In the present perfect, we use “have” or “has” plus the past participle form of the verb. “Been” is used when we talk about life experience with places. The question asks whether the person has had the experience of visiting Germany at any time in life.

Question 14 Explanation

The correct answer is carefully. We use an adverb to describe how someone performs an action. “Drives” is a verb, so it needs an adverb, not an adjective. The sentence means that he drives with care when the weather is bad.

Question 15 Explanation

The correct answer is to. We use “to” plus the base verb to express purpose. In this sentence, the reason for going to the shop was buying bread. This purpose structure is common in everyday English and exam sentences.

Question 16 Explanation

The correct answer is much. We use “much” with uncountable nouns, especially in negative sentences and questions. “Information” is uncountable in English, so it cannot be used with “many.” The sentence means that only a small amount of information is available.

Question 17 Explanation

The correct answer is was. The sentence describes a past state connected to a past event. “Heard the news” shows that the situation happened in the past. Therefore, the past form of “be” is needed to describe her feeling at that time.

Question 18 Explanation

The correct answer is at. The adjective “good” is commonly followed by “at” when we talk about skills or abilities. “Solving difficult problems” is an activity or skill. Therefore, the natural phrase is “good at solving difficult problems.”

Question 19 Explanation

The correct answer is done. In the present perfect, we use “have” or “has” plus a past participle. The past participle of “do” is “done.” The word “already” also commonly appears in present perfect sentences to show that something has happened earlier than expected.

Question 20 Explanation

The correct answer is goes. We use the present simple for habits and routines. The word “usually” shows that this is a regular action. Because the subject is “he,” the verb needs the third-person singular form.

Question 21 Explanation

The correct answer is saw. We use the past simple for completed actions at a finished time in the past. “Yesterday evening” is a specific past time expression. Therefore, the past simple form of the verb is required.

Question 22 Explanation

The correct answer is shouldn’t. We use “shouldn’t” to give advice about something that is not a good idea. The sentence explains that eating too much fast food is unhealthy. Therefore, the speaker is giving negative advice.

Question 23 Explanation

The correct answer is where. We use “where” in relative clauses when we refer to a place. In this sentence, “the house” is the place connected to the grandparents’ living. The relative clause tells us more about that house.

Question 24 Explanation

The correct answer is living. After “be used to,” we use a noun or a gerund form. This structure describes something that is familiar or normal for someone. In this sentence, living in a busy city is something she is accustomed to.

Question 25 Explanation

The correct answer is since. We use “since” with a starting point in time. The year 2019 is the point when the relationship or knowing began. The present perfect shows that the situation started in the past and continues now.

Question 26 Explanation

The correct answer is the. We use “the” before superlative adjectives such as “most expensive,” “best,” and “largest.” A superlative identifies one item as number one in a group. In this sentence, one phone is being identified as the most expensive phone in the shop.

Question 27 Explanation

The correct answer is where. We use “where” when asking about place or location. The sentence is an indirect question, so the word order is “where the station is,” not “where is the station.” This structure is common in polite questions.

Question 28 Explanation

The correct answer is so. We use “so” to show a result or consequence. The first part explains the cause: the speaker was tired. The second part gives the result: the speaker went to bed early.

Question 29 Explanation

The correct answer is little. We use “little” with uncountable nouns to mean not much. “Money” is uncountable in English, and the sentence has a negative meaning because she cannot buy a new laptop. Therefore, “little” fits both the grammar and the meaning.

Question 30 Explanation

The correct answer is would accept. This is a second conditional structure used for advice or an imaginary situation. The phrase “If I were you” is followed by “would” plus the base verb in the main clause. The sentence means that the speaker is giving advice about what they would do in the listener’s situation.
