The given sentence is in direct speech. Its indirect speech will be: She said to me that I had exceeded my time limit. While changing from direct to indirect speech, simple past tense sentence changes into past perfect tense. The structure of the new past perfect tense sentence becomes (subject+had+3^rd form of verb+object).

When the exact words spoken by the speaker are repeated or quoted then such speech is known as direct speech. Here, in the given sentence, is an interrogative sentence. For interchanging the speech into direct form, the verb ‘inform’ changed to ‘had informed’ and for dropping inverted comma, conjunction whether is used, ‘said’ changed to ‘asked’, ‘yesterday’ changed to ‘day before’. All other given options are inappropriate. So, the direct narration of the given sentence will be: The Principal said to me, “Did you inform the Chief Guest the revised schedule yesterday?”

There is error in the second part of the statement. The correct statement would be: ‘My father asked me why you are taking that examination’. The past tense of the sentence is already represented by the word ‘asked’ and thus the auxiliary verb will be ‘are’ and not ‘were’.

There is error in the second part of the sentence. The correct sentence will be: ‘Ram told me he gets up early in the morning daily’. The direct speech reports a simple present tense sentence. Thus, first form of the verb with a –s will be used.

There is error in the first part of the sentence. The correct sentence will be: ‘He proposed that we should go to the Disco and then have dinner at a restaurant’. There will be no pronoun before that.

There are three types of interrogative determiners viz when what, and whose.
