please help me if you know it's urgent!​

Answer 1

what I had been doing since morning?

Answer 2

While negative claims something to be false interrogative asks a question.

• A statement seeking a question or a query is referred to as interrogative sentence. It is generally used to refer to features that form queries.
• Negative sentences, present the sentence in denial. They are declarative statements.
• Thus, the sentences are -

1. Interrogative - Had I been doing this work since morning?
2. Negative - I hadn't been doing this work since morning.
