Answer Explanations<\/h1>\n

Question 1 Explanation<\/h2>\n

The correct answer is has worked<\/strong>. We use the present perfect with \u201csince\u201d to show that an action started in the past and continues up to now. In this sentence, she started working in the company in 2021, and she still works there now.<\/p>\n

Question 2 Explanation<\/h2>\n

The correct answer is rang<\/strong>. We use the past simple for a completed action that interrupted another action in progress. \u201cWas watching\u201d shows the longer background action, and \u201crang\u201d shows the shorter action that happened suddenly.<\/p>\n

Question 3 Explanation<\/h2>\n

The correct answer is will stay<\/strong>. This is a first conditional sentence, which is used for a real possible future situation. The \u201cif\u201d clause uses the present simple, and the main clause uses \u201cwill\u201d plus the base verb.<\/p>\n

Question 4 Explanation<\/h2>\n

The correct answer is mustn\u2019t<\/strong>. We use \u201cmustn\u2019t\u201d when something is prohibited or not allowed. The sentence says smoking is not allowed in the building, so the meaning is strong prohibition.<\/p>\n

Question 5 Explanation<\/h2>\n

The correct answer is much<\/strong>. We use \u201cmuch\u201d with uncountable nouns, especially in negative sentences and questions. \u201cSugar\u201d is uncountable when we talk about it as a general amount, so this quantifier is correct.<\/p>\n

Question 6 Explanation<\/h2>\n

The correct answer is an<\/strong>. We use \u201can\u201d before a singular countable noun when the following word begins with a vowel sound. \u201cHonest\u201d begins with a silent \u201ch,\u201d so the first sound is a vowel sound.<\/p>\n

Question 7 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, the hotel is the place in which the speakers stayed last summer.<\/p>\n

Question 8 Explanation<\/h2>\n

The correct answer is at<\/strong>. The adjective \u201cgood\u201d and comparative expression \u201cbetter\u201d are commonly followed by \u201cat\u201d when we talk about skills or activities. Since playing tennis is an ability, \u201cat\u201d is the correct preposition.<\/p>\n

Question 9 Explanation<\/h2>\n

The correct answer is reading<\/strong>. After the verb \u201cenjoy,\u201d we usually use a gerund form. A gerund is the -ing form of a verb used like a noun, so \u201creading\u201d fits correctly here.<\/p>\n

Question 10 Explanation<\/h2>\n

The correct answer is to buy<\/strong>. After the verb \u201cdecide,\u201d we usually use an infinitive with \u201cto.\u201d The sentence means that they made a decision about a future action.<\/p>\n

Question 11 Explanation<\/h2>\n

The correct answer is more difficult<\/strong>. We use comparative forms to compare two things. Because \u201cdifficult\u201d is a longer adjective, we form the comparative with \u201cmore.\u201d<\/p>\n

Question 12 Explanation<\/h2>\n

The correct answer is was sent<\/strong>. This sentence uses the passive voice because the focus is on the letter, not on the person who sent it. For a past passive sentence, we use \u201cwas\u201d or \u201cwere\u201d plus the past participle.<\/p>\n

Question 13 Explanation<\/h2>\n

The correct answer is eaten<\/strong>. In the present perfect, we use \u201chave\u201d or \u201chas\u201d plus the past participle form of the verb. The past participle of \u201ceat\u201d is \u201ceaten,\u201d so it is needed after \u201chave never.\u201d<\/p>\n

Question 14 Explanation<\/h2>\n

The correct answer is well<\/strong>. We use an adverb to describe how someone does an action. Since \u201cspeaks\u201d is a verb, the adverb \u201cwell\u201d is correct instead of the adjective \u201cgood.\u201d<\/p>\n

Question 15 Explanation<\/h2>\n

The correct answer is to<\/strong>. We use \u201cto\u201d plus the base verb to show purpose. In this sentence, leaving early has a purpose, and that purpose is catching the train.<\/p>\n

Question 16 Explanation<\/h2>\n

The correct answer is a lot of<\/strong>. We can use \u201ca lot of\u201d with plural countable nouns and uncountable nouns. \u201cPeople\u201d is plural in meaning, and the sentence describes a large number of people.<\/p>\n

Question 17 Explanation<\/h2>\n

The correct answer is was<\/strong>. The sentence refers to a completed past situation because it explains why he did not go to school. \u201cIll\u201d describes his state at that past time, so the past form of \u201cbe\u201d is needed.<\/p>\n

Question 18 Explanation<\/h2>\n

The correct answer is in<\/strong>. The adjective \u201cinterested\u201d is usually followed by the preposition \u201cin.\u201d The sentence means that photography is a subject or activity that attracts his attention.<\/p>\n

Question 19 Explanation<\/h2>\n

The correct answer is yet<\/strong>. We commonly use \u201cyet\u201d in negative present perfect sentences to mean that something has not happened up to now. It usually comes at the end of the sentence.<\/p>\n

Question 20 Explanation<\/h2>\n

The correct answer is has<\/strong>. We use the present simple for routines and habits. The word \u201cusually\u201d shows that this is a regular action, so the third-person singular form \u201chas\u201d is correct.<\/p>\n

Question 21 Explanation<\/h2>\n

The correct answer is went<\/strong>. We use the past simple for completed actions at a specific past time. \u201cLast night\u201d clearly shows a finished time in the past, so the past simple form is needed.<\/p>\n

Question 22 Explanation<\/h2>\n

The correct answer is should<\/strong>. We use \u201cshould\u201d to give advice or make a recommendation. The sentence says the person looks tired, so taking a break is a sensible suggestion.<\/p>\n

Question 23 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 man\u201d is the person who helped the speaker yesterday.<\/p>\n

Question 24 Explanation<\/h2>\n

The correct answer is waking up<\/strong>. After \u201cbe used to,\u201d we use a noun or gerund form, not the base verb. The sentence means that getting up early on Sundays is not a normal or familiar habit for the speaker.<\/p>\n

Question 25 Explanation<\/h2>\n

The correct answer is for<\/strong>. We use \u201cfor\u201d with a period of time, such as ten years, two months, or three days. The sentence describes how long the speakers have lived in that place.<\/p>\n

Question 26 Explanation<\/h2>\n

The correct answer is the best<\/strong>. We use the superlative form when we compare one person or thing with all others in a group. Since the sentence compares her with all students in the class, the superlative form is required.<\/p>\n

Question 27 Explanation<\/h2>\n

The correct answer is why<\/strong>. We use \u201cwhy\u201d when we talk about a reason. In this sentence, the speaker does not know the reason for his lateness.<\/p>\n

Question 28 Explanation<\/h2>\n

The correct answer is while<\/strong>. We use \u201cwhile\u201d to show that two actions were happening at the same time. In this sentence, the children were playing and their mother was cooking during the same period.<\/p>\n

Question 29 Explanation<\/h2>\n

The correct answer is few<\/strong>. We use \u201cfew\u201d with plural countable nouns to mean not many. \u201cFriends\u201d is a plural countable noun, and the sentence has a negative meaning because he feels lonely.<\/p>\n

Question 30 Explanation<\/h2>\n

The correct answer is had<\/strong>. This is a second conditional sentence, which is used for unreal or unlikely situations in the present or future. In the \u201cif\u201d clause of the second conditional, we use the past simple form.<\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n
