Q1  20
Q1 20

Question 1: She ___ a student.

Question 1 options
'is' is correct because the subject 'she' requires the third-person singular form of 'be.' 'am' is used with 'I,' 'are' is used with 'you/we/they,' and 'be' is the base form, not a conjugated form.
Q2 20

Question 2: I have two ___.

Question 2 options
'cats' is correct because the plural of 'cat' is formed by adding -s. 'cat' is singular, 'cates' is a misspelling, and 'caties' is not a real English word.
Q3 20

Question 3: He ___ to school every day.

Question 3 options
'goes' is correct because the subject 'he' is third-person singular, so the verb needs an -es ending in the present simple. 'go' lacks the -es ending, 'going' would need a helping verb, and 'gos' is an incorrect spelling.
Q4 20

Question 4: This book is ___. It belongs to me.

Question 4 options
'mine' is the correct possessive pronoun meaning 'belonging to me.' 'My' is a possessive adjective and needs a noun after it, so it doesn't work alone here.
Q5 20

Question 5: We went to the park, and we ___ a great time yesterday.

Question 5 options
'had' is correct because the sentence refers to a completed action in the past ('yesterday'). 'have' is present tense, 'has' is present tense for third person, and 'having' is a participle that needs a helping verb.
Q6 20

Question 6: The sentence 'She don't like coffee' is grammatically correct.

Question 6 options
False because 'she' is a third-person singular subject and requires 'doesn't,' not 'don't.' The correct sentence is 'She doesn't like coffee.'
Q7 20

Question 7: There are ___ apples on the table.

Question 7 options
'some' is correct because 'apples' is a countable plural noun in a positive statement. 'much' is used with uncountable nouns, 'a' is used with singular nouns, and 'an' is also singular.
Q8 20

Question 8: The data ___ that the experiment was successful, which contradicted the initial hypothesis.

Question 8 options
'suggest' is correct because in formal English, 'data' is treated as a plural noun (the plural of 'datum'). 'Suggests' would be used if 'data' were treated as singular, which is less formal. 'Is suggesting' changes the tense context, and 'has suggested' implies relevance to the present, which conflicts with the past-tense narrative.
Q9 20

Question 9: I am interested ___ learning new languages.

Question 9 options
'in' is correct because the adjective 'interested' collocates with the preposition 'in.' Using 'at,' 'for,' or 'on' after 'interested' is a common grammar mistake.
Q10 20

Question 10: The movie was very ___. I almost fell asleep.

Question 10 options
'boring' is correct because -ing adjectives describe the quality of the thing causing the feeling. The movie caused boredom. 'Bored' describes how a person feels, not the movie itself. 'Bore' is a verb, and 'boringly' is an adverb.
Q11 20

Question 11: The sentence 'I have been to Paris last year' is grammatically correct.

Question 11 options
False because 'last year' is a specific finished time, which requires the past simple ('I went to Paris last year'). The present perfect ('have been') is not used with definite past time expressions.
Q12 20

Question 12: She gave the gift to my brother and ___.

Question 12 options
'me' is correct because 'my brother and me' is the object of the preposition 'to.' A common mistake is using 'I' in object position. A good test: remove 'my brother and' — you would say 'She gave the gift to me,' not 'to I.'
Q13 20

Question 13: If I ___ enough money, I would buy a new car.

Question 13 options
'had' is correct because this is a second conditional sentence (hypothetical present/future). The second conditional uses 'if + past simple' in the condition clause. 'have' would be first conditional, 'would have' belongs in the result clause, and 'will have' mixes conditional structures incorrectly.
Q14 20

Question 14: Match each incorrect sentence with the type of grammar mistake it contains.

Question 14 options
He don't know the answer.
She is more smarter than him.
I am agree with you.
He told to me a secret.
Double comparative error
Unnecessary auxiliary verb
Subject-verb agreement error
Wrong preposition usage

Select an item on the left, then tap its match on the right.

'He don't know' has a subject-verb agreement error (should be 'doesn't'). 'She is more smarter' has a double comparative error. 'I am agree with you' misuses the verb (should be 'I agree'). 'He told to me' has a wrong preposition (should be 'He told me').
Q15 20

Question 15: Which sentence is correct?

Question 15 options
'Each of the students has a textbook' is correct because 'each' is a singular indefinite pronoun and requires the singular verb 'has.' 'Have' is a plural verb form, 'are having' changes the meaning, and 'has got' with 'students' instead of 'each' would need 'have got.'
Q16 20

Question 16: She suggested ___ to the museum instead of the cinema.

Question 16 options
'going' is correct because the verb 'suggest' is followed by a gerund (-ing form), not an infinitive. 'To go' is an infinitive form that doesn't follow 'suggest.' 'Go' alone is ungrammatical here, and 'we going' lacks a proper clause structure.
Q17 20

Question 17: Despite ___ tired, she continued working on the report until midnight.

Question 17 options
'being' is correct because 'despite' is a preposition and must be followed by a noun or gerund (-ing form). 'She was' creates a clause, which requires 'although' instead. 'Was' alone is incomplete, and 'to be' is an infinitive, which doesn't follow 'despite.'
Q18 20

Question 18: Put these words in the correct order to form a grammatically correct sentence:

Question 18 options
  • about the changes.
  • were informed
  • Neither the manager
  • nor the employees

Drag items or use arrows to arrange them in the correct order.

The correct order is 'Neither the manager nor the employees were informed about the changes.' 'Neither...nor' is a correlative conjunction, and when the subject closer to the verb is plural ('employees'), the verb takes the plural form 'were.'
Q19 20

Question 19: The number of people who ___ bilingual is increasing every year worldwide.

Question 19 options
'are' is correct because the relative pronoun 'who' refers to 'people' (plural), so the verb in the relative clause must be plural. 'Is' would agree with 'number' but here the verb is inside the 'who' clause modifying 'people.' 'Was' is wrong tense, and 'been' needs a helping verb.
Q20 20

Question 20: Had she ___ the email earlier, she would have responded before the deadline.

Question 20 options
'seen' is correct because this is the third conditional (past unreal), which uses 'had + past participle' in the if-clause. The inverted form 'Had she seen' replaces 'If she had seen.' 'Saw' is the simple past and incorrect after 'had.'
