What are some examples of changing interrogative sentence to question?

You're actually asking about a common misconception! "Interrogative sentence" and "question" are essentially synonymous. They both refer to sentences that seek information.

Let me clarify:

* Interrogative Sentence: A sentence that asks a question. It is characterized by its structure (often starting with a question word or auxiliary verb) and punctuation (ending with a question mark).

* Question: This is a general term for any utterance seeking information. It can be expressed as a complete sentence, a phrase, or even a single word.

It's not about "changing" an interrogative sentence into a question, but rather understanding that they are the same thing.

However, you might be interested in the different ways we can phrase a question, which can have a slightly different impact on the interaction:

Examples:

* Formal: "Could you please tell me the time?"

* Informal: "What time is it?"

* Direct: "Tell me the time."

* Indirect: "I was wondering if you could tell me the time."

Ultimately, it's about choosing the appropriate way to ask a question based on the context and your desired level of formality.
