Answer 2

Question: Can you please provide the sentences in both interrogative and negative forms?

Original Sentences: 1. Their office hours begin at 9 o'clock. 2. Mr. Bell is busy all day.

Interrogative Form:

To convert the original sentences into interrogative form, we need to rearrange the word order and add a question mark at the end of the sentence.

1. Do their office hours begin at 9 o'clock? 2. Is Mr. Bell busy all day?

Negative Form:

To convert the original sentences into negative form, we need to add the word "not" after the auxiliary verb "do" or "is".

1. Their office hours do not begin at 9 o'clock. 2. Mr. Bell is not busy all day.

Please note that in the negative form, "do not" is used for the verb "begin" in the first sentence, while "is not" is used for the verb "busy" in the second sentence.
