DIRECTIONS: The following sentences are given in reported speech. Change these sentences into Direct speech: 

The teacher said that the sun rises in the east. 

The correct answer is The teacher said, "The sun rises in the east"

Key Points

• Reported speech is used to report or repeat what someone else has said.
• In the given sentence, "The teacher said" is an indicator of reported speech.
• To convert reported speech into direct speech, we remove the reporting verb, change pronouns and tenses as required, and put the quote marks around the actual words spoken.
• When the reported clause/statement of a direct speech is a universal truth speech or any historical event or a habitual action (a part of the daily routine), then the tense in the indirect speech doesn't change, no matter in whatever tense the reporting verb (say/said) is, which is highlighted in the given indirect form.
• "The teacher said" is in the past tense, indicating that the statement was made in the past and the original statement is "The sun rises in the east", is a universal truth so the correct sentence in Direct speech would be The teacher said, "The sun rises in the east".

Thus, option 2 is the correct answer.
