Option D) Did is correct because:
- It properly forms the past simple tense.
- It agrees with the subject "he."
Option Analysis:

Have - Incorrect. "Have" is used for present perfect, not past simple.

. This sentence structure is appropriate and follows the proper usage of the modal auxiliary verb "may" to request permission. The subject "I" and the main verb "use" are correctly placed.
Option Analysis:
Option A:
Incorrect as it uses a gerund form ("using") instead of the base form of the verb.
Option B:
Correct, as it is the proper use of "may" for permission.
Option C:
Incorrect because it places "I may" incorrectly; it should be a question starting with "May I".

Option Analysis:
Option A:
This option suggests she prefers staying home. The original statement does not indicate any preference for staying at home.

This option implies she dislikes visiting her grandmother, which contradicts the given sentence that expresses a desire to visit.
Option C:
This is correct as it accurately reflects the sentiment expressed in the original statement.

A) You don't come to my house.
B) I'm glad to be with you here.
C) May I sleep at your house tonight?.
D) I must back home immediately. It's almost dark.
Show Answer
Explanations:
Option D is correct because it appropriately uses the modal auxiliary "must" to express a sense of urgency and necessity, which fits well with the context of Syifa's concern about Elsa's safety as it gets dark. The phrase "It's almost dark" further reinforces this urgency.
Option Analysis:
Option A:
This option does not fit the context as there is no indication that someone is avoiding going to a house.
Option B:
This option uses "I'm glad," which is not a modal auxiliary and does not address the urgency of the situation.

Option Analysis:
Option A:
"Could take" suggests ability but not necessarily a habitual action.
Option B:

Option D:
None of the above - Incorrect since "Must" is the appropriate choice.
Frequently Asked Questions
What are modal auxiliaries?
Modal auxiliaries are a type of verb that express modality, which includes concepts such as ability, permission, advice, and likelihood. They modify the main verb in a sentence to indicate these different meanings.
How do modal auxiliaries differ from other verbs?
Modal auxiliaries cannot stand alone as complete verbs; they must be followed by a main verb. They are used to express various shades of meaning, such as possibility, necessity, and permission, which sets them apart from regular verbs.
Can you give an example of using modal auxiliaries for future actions?
Certainly! For instance, "We would go to the park if it doesn't rain tomorrow" uses 'would' to express a hypothetical future action and 'doesn't' to indicate a condition that must be met.
What is the difference between using modal auxiliaries for permission and for prohibition?
Modal auxiliaries like 'may' are used to ask or give permission, while 'mustn't' or 'shouldn't' indicate prohibition. For example, "You may enter the room" allows entry, whereas "You mustn't touch that" forbids it.
How are modal auxiliaries used in recommendations?
Modal auxiliaries such as 'should' and 'could' are often used to make recommendations. For example, "You should eat more vegetables" suggests a course of action, while "Could you help me with this?" requests assistance politely.
