Special questions (or "Wh"-questions)
To make a "Wh" question we usually put a question word (QW) before a construction of "Yes/No" questions:
QW + had + S + V3 … ?
E.g.
What had you done by ten o'clock yesterday?
 
SHORT ANSWERS
Yes, S + had. No, S hadn't.
Yes, I had. No, I hadn't.
Yes, we had. No, we hadn't.
Yes, you had. No, you hadn't.
Yes, they had. No, they hadn't.
Yes, he had. No, he hadn't.
Yes, she had. No, she hadn't.

NOTE!
In short answers we use pronouns (I, we, you, they, he, she, it).
E.g.
— Had John done his homework by ten o'clock yesterday?
— No, he hadn't. (NOT: No, John hadn't.)

S — Subject of the sentence. E.g. I, we, you, they, he, she, it, Mary, John, my friends
V3 — Verb in the 3rd form (Past Participle). E.g. written, gone, listened, etc.
