Answer 1

   Negative Sentences:

       We use "didn't" (short for "did not") to make negative sentences.

       Combine "didn't" with the base form of the main verb.

       Example: He didn't use buses or planes.

   Questions:

       In questions, we use "did" as an auxiliary verb.

       Place "did" at the beginning of the question.

       Use the base form of the main verb.

       Example: Why did Daniel do this?

   Short Answers:

       In short answers, use "did" (for affirmative) or "didn't" (for negative).

       When giving short negative answers, use "didn't."

       Example (Affirmative): Yes, he did.

       Example (Negative): No, he didn't.
