Step-by-step explanation:
Negative sentences are described as the sentences that aim to neglect or deny the truth or validity of a statement or assertion. Such sentences involve a word like 'not' or 'no' to signal the denial. While interrogative sentences aim to denote a question that a speaker wishes to ask and these sentences are marked with a question mark(?) and an interrogative word(either yes/no type questions or using 'wh' family words).
