Answer Explanations<\/h1>\n

Question 1 Explanation<\/h2>\n

The correct answer is have lost<\/strong>. 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.<\/p>\n

Question 2 Explanation<\/h2>\n

The correct answer is went<\/strong>. We use the past simple for a completed action that interrupted another longer action in the past. \u201cWere having dinner\u201d shows the background action, and \u201cwent out\u201d shows the sudden event. This structure is common when one action happens in the middle of another action.<\/p>\n

Question 3 Explanation<\/h2>\n

The correct answer is will get<\/strong>. This sentence is a first conditional because it talks about a real possible future result. The \u201cif\u201d clause uses the present simple, and the main clause uses \u201cwill\u201d plus the base verb. The meaning is that regular study can realistically lead to better results.<\/p>\n

Question 4 Explanation<\/h2>\n

The correct answer is must<\/strong>. We use \u201cmust\u201d 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.<\/p>\n

Question 5 Explanation<\/h2>\n

The correct answer is many<\/strong>. We use \u201cmany\u201d with plural countable nouns. \u201cMistakes\u201d is plural and countable because mistakes can be counted one by one. The sentence means that the report contains a large number of errors.<\/p>\n

Question 6 Explanation<\/h2>\n

The correct answer is an<\/strong>. We use \u201can\u201d before a singular countable noun when the next word begins with a vowel sound. \u201cUmbrella\u201d begins with a vowel sound, so \u201can\u201d is correct. The sentence introduces one umbrella in a general way.<\/p>\n

Question 7 Explanation<\/h2>\n

The correct answer is who<\/strong>. We use \u201cwho\u201d in relative clauses when we refer to people. In this sentence, \u201cthe teacher\u201d is a person, and the relative clause gives extra information about that person. The clause explains which teacher the speaker means.<\/p>\n

Question 8 Explanation<\/h2>\n

The correct answer is of<\/strong>. The adjective \u201cafraid\u201d is commonly followed by the preposition \u201cof.\u201d The phrase \u201cafraid of flying\u201d means that flying makes him feel fear or anxiety. This is a fixed adjective-preposition combination that learners should remember.<\/p>\n

Question 9 Explanation<\/h2>\n

The correct answer is working<\/strong>. After \u201cdon\u2019t mind,\u201d 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.<\/p>\n

Question 10 Explanation<\/h2>\n

The correct answer is to call<\/strong>. After the verb \u201cpromise,\u201d we normally use the infinitive form with \u201cto.\u201d The sentence means that she made a promise about a future action. Because the action happens after the promise, the infinitive structure is required.<\/p>\n

Question 11 Explanation<\/h2>\n

The correct answer is larger<\/strong>. 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 \u201clarge\u201d is a short adjective, the comparative form is made by adding \u201c-er.\u201d<\/p>\n

Question 12 Explanation<\/h2>\n

The correct answer is are cleaned<\/strong>. This sentence uses the passive voice because the focus is on the windows, not on the person who cleans them. The phrase \u201cevery Friday\u201d shows a regular action, so the present simple passive is needed. The structure is \u201care\u201d plus the past participle.<\/p>\n

Question 13 Explanation<\/h2>\n

The correct answer is been<\/strong>. In the present perfect, we use \u201chave\u201d or \u201chas\u201d plus the past participle form of the verb. \u201cBeen\u201d 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.<\/p>\n

Question 14 Explanation<\/h2>\n

The correct answer is carefully<\/strong>. We use an adverb to describe how someone performs an action. \u201cDrives\u201d is a verb, so it needs an adverb, not an adjective. The sentence means that he drives with care when the weather is bad.<\/p>\n

Question 15 Explanation<\/h2>\n

The correct answer is to<\/strong>. We use \u201cto\u201d 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.<\/p>\n

Question 16 Explanation<\/h2>\n

The correct answer is much<\/strong>. We use \u201cmuch\u201d with uncountable nouns, especially in negative sentences and questions. \u201cInformation\u201d is uncountable in English, so it cannot be used with \u201cmany.\u201d The sentence means that only a small amount of information is available.<\/p>\n

Question 17 Explanation<\/h2>\n

The correct answer is was<\/strong>. The sentence describes a past state connected to a past event. \u201cHeard the news\u201d shows that the situation happened in the past. Therefore, the past form of \u201cbe\u201d is needed to describe her feeling at that time.<\/p>\n

Question 18 Explanation<\/h2>\n

The correct answer is at<\/strong>. The adjective \u201cgood\u201d is commonly followed by \u201cat\u201d when we talk about skills or abilities. \u201cSolving difficult problems\u201d is an activity or skill. Therefore, the natural phrase is \u201cgood at solving difficult problems.\u201d<\/p>\n

Question 19 Explanation<\/h2>\n

The correct answer is done<\/strong>. In the present perfect, we use \u201chave\u201d or \u201chas\u201d plus a past participle. The past participle of \u201cdo\u201d is \u201cdone.\u201d The word \u201calready\u201d also commonly appears in present perfect sentences to show that something has happened earlier than expected.<\/p>\n

Question 20 Explanation<\/h2>\n

The correct answer is goes<\/strong>. We use the present simple for habits and routines. The word \u201cusually\u201d shows that this is a regular action. Because the subject is \u201che,\u201d the verb needs the third-person singular form.<\/p>\n

Question 21 Explanation<\/h2>\n

The correct answer is saw<\/strong>. We use the past simple for completed actions at a finished time in the past. \u201cYesterday evening\u201d is a specific past time expression. Therefore, the past simple form of the verb is required.<\/p>\n

Question 22 Explanation<\/h2>\n

The correct answer is shouldn\u2019t<\/strong>. We use \u201cshouldn\u2019t\u201d 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.<\/p>\n

Question 23 Explanation<\/h2>\n

The correct answer is where<\/strong>. We use \u201cwhere\u201d in relative clauses when we refer to a place. In this sentence, \u201cthe house\u201d is the place connected to the grandparents\u2019 living. The relative clause tells us more about that house.<\/p>\n

Question 24 Explanation<\/h2>\n

The correct answer is living<\/strong>. After \u201cbe used to,\u201d 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.<\/p>\n

Question 25 Explanation<\/h2>\n

The correct answer is since<\/strong>. We use \u201csince\u201d 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.<\/p>\n

Question 26 Explanation<\/h2>\n

The correct answer is the<\/strong>. We use \u201cthe\u201d before superlative adjectives such as \u201cmost expensive,\u201d \u201cbest,\u201d and \u201clargest.\u201d 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.<\/p>\n

Question 27 Explanation<\/h2>\n

The correct answer is where<\/strong>. We use \u201cwhere\u201d when asking about place or location. The sentence is an indirect question, so the word order is \u201cwhere the station is,\u201d not \u201cwhere is the station.\u201d This structure is common in polite questions.<\/p>\n

Question 28 Explanation<\/h2>\n

The correct answer is so<\/strong>. We use \u201cso\u201d 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.<\/p>\n

Question 29 Explanation<\/h2>\n

The correct answer is little<\/strong>. We use \u201clittle\u201d with uncountable nouns to mean not much. \u201cMoney\u201d is uncountable in English, and the sentence has a negative meaning because she cannot buy a new laptop. Therefore, \u201clittle\u201d fits both the grammar and the meaning.<\/p>\n

Question 30 Explanation<\/h2>\n

The correct answer is would accept<\/strong>. This is a second conditional structure used for advice or an imaginary situation. The phrase \u201cIf I were you\u201d is followed by \u201cwould\u201d 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\u2019s situation.<\/p>\n","protected":false},"excerpt":{"rendered":"
