Q1  15
Q1 15

Question 1: She ___ speak three languages fluently when she was a child.

Question 1 options
'Could' is correct because it expresses past ability. 'Can' is present tense, 'must' expresses obligation, and 'shall' is used for offers or suggestions — none of these refer to past ability.
Q2 15

Question 2: You ___ wear a seatbelt in the car. It is the law.

Question 2 options
'Must' is correct because it expresses strong obligation or necessity, which matches the context of a legal requirement. 'Might' expresses slight possibility, 'would' is used for requests or preferences, and 'shall' is used for offers — none fit a legal obligation.
Q3 15

Question 3: Modal verbs are always followed by a verb in its base (infinitive without 'to') form.

Question 3 options
True because a core rule of modal verbs is that they are followed directly by the base form of a verb without 'to' (e.g. 'She can swim', not 'She can to swim'). This applies to all standard modal verbs such as can, could, must, should, will, and may.
Q4 15

Question 4: What does 'may' express in this sentence: 'It may rain this afternoon, so take an umbrella.'?

Question 4 options
'May' in this sentence expresses possibility — the speaker is saying that rain is possible but not certain. It does not express permission, obligation, or past ability in this context.
Q5 15

Question 5: Arrange the words to make a correct sentence:

Question 5 options
  • every day
  • more water
  • drink
  • should
  • You

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

The correct order is 'You should drink more water every day' because modal verbs ('should') come before the base form of the main verb ('drink'), and the object and time phrase follow naturally.
Q6 15

Question 6: Which sentence is grammatically correct?

Question 6 options
'She must finish her homework before dinner' is correct because modal verbs are followed by the base form of the verb. 'Must to finish' incorrectly adds 'to', 'must finishing' incorrectly uses the -ing form, and 'must finished' incorrectly uses the past participle.
Q7 15

Question 7: Customer: 'I'd like to try on these shoes.' Shop assistant: '___ I bring you a different size as well?'

Question 7 options
'Shall' is correct because it is used by the speaker to make an offer or ask what the listener would like. 'Must' expresses obligation, 'might' expresses slight possibility, and 'could' in this position would be a request rather than an offer from the assistant.
Q8 15

Question 8: Which sentence correctly uses 'must' to express deduction (not obligation)?

Question 8 options
'She must be exhausted after working for twelve hours' uses 'must' to express a logical deduction — the speaker concludes something is almost certainly true based on evidence. The other options use 'must' to express obligation or prohibition, not deduction.
Q9 15

Question 9: Put the words in the correct order:

Question 9 options
  • might not
  • arrive
  • He
  • tonight
  • on time

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

The correct order is 'He might not arrive on time tonight' because 'might not' must stay together as the negative modal form, followed by the base verb 'arrive' and then the adverbial phrases.
Q10 15

Question 10: The doctor says I ___ avoid eating too much sugar if I want to stay healthy.

Question 10 options
'Should' is the best completion because it expresses advice or a recommendation from the doctor. 'Mustn't' expresses strong prohibition, 'will' expresses a future certainty or promise, and 'shall' is used for offers or suggestions — none carry the same sense of personal health advice.
Q11 15

Question 11: A student says: 'I studied all week, so I should pass the exam.' Which statement about the use of 'should' here is true?

Question 11 options
'Should' in this sentence expresses a logical deduction based on the evidence (studying all week). It does not ask for permission, express an order, or refer to past ability — it shows the speaker's reasoned expectation about a likely outcome.
Q12 15

Question 12: Original: 'It is necessary for you to submit the form today.' Transformed: 'You ___ submit the form today.'

Question 12 options
'Must' correctly transforms the idea of necessity or strong obligation. 'Might' expresses possibility, 'would' expresses preference or request, and 'could' expresses ability or possibility — none carry the same meaning of necessity as 'must'.
Q13 15

Question 13: Match each sentence to the correct grammar label.

Question 13 options
I can ride a bike without using my hands.
He must be the new manager — everyone is listening to him.
May I leave the room for a moment?
You should call your grandmother more often.
Modal verb expressing logical deduction
Modal verb expressing a request for permission
Modal verb expressing advice
Modal verb expressing ability

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

Modal verbs express different meanings: 'can' for ability, 'must' for deduction, 'may' for permission, and 'should' for advice. Context determines which function a modal verb is performing.
Q14 15

Question 14: 'Must' and 'have to' always have exactly the same meaning and can be used interchangeably in every situation.

Question 14 options
False because while both 'must' and 'have to' express obligation, 'must' typically reflects a personal or internal obligation (e.g. 'I must call her — I feel bad'), whereas 'have to' often refers to an external rule or requirement (e.g. 'I have to wear a uniform at work'). Additionally, 'don't have to' means there is no obligation, while 'mustn't' expresses prohibition — opposite meanings.
Q15 15

Question 15: Which sentence is more appropriate when asking a stranger politely for permission to use their phone?

Question 15 options
'May I use your phone for a moment?' is more appropriate because 'may' is the more formal and polite register for requesting permission from someone you don't know well. 'Can I use your phone?' is grammatically possible but considered less formal. The other two options use 'should' and 'must', which do not express requests for permission.
