Correct Answer: The teacher makes the students complete their homework every day.

Explanation:

• "Make" is a causative verb, which is used when the subject causes someone else to perform an action. In this case, the teacher (subject) causes the students (object) to complete their homework (action).

• Structure of causative verb with "make":

  • Make + object + base form of verb

  • Example: She makes her kids brush their teeth before bed.

  • Example: My boss makes me stay late at work sometimes.

• Important Note: Unlike other verbs, after "make," the verb following the object is always in its base form, not infinitive or gerund.

• This sentence is an independent clause because it expresses a complete thought and can stand alone.

More Examples:

• Parents make their children do household chores.

• The coach makes the players run extra laps for practice.

• Teachers make students revise their lessons regularly.

Explanation:

When converting direct speech to indirect speech (assertive sentences):

1. Remove the quotation marks and introduce a conjunction like that after the reporting verb (said, told).

2. Change the pronouns according to the subject and object.

3. Adjust the tense if the reporting verb is in the past:

   • Modal verbs like must generally change to had to in the past tense, unless expressing eternal truths.

Example:

• Direct: Kalim said, "I must go there."

• Indirect: Kalim said that he had to go there.

Other options are wrong because:

• ক) “I” is not changed to “he” → incorrect pronoun

• খ) “must” is unchanged → past context usually requires had to

• ঘ) “must had to” → grammatically incorrect; two modal verbs cannot be used together
