—¿les dinero a los pobres?
—no, pero yo les ropa y comida.
diste; di
hiciste; dio
diste; dio
diste; hizo

For this case we can translate the dialogue given as:

Do you money to the poor?

No, but I give them clothes and food.

It is noted that the first sentence is based on a question addressed to a second person.

We conjugate the verb "Dar" in imperative mode (simple preterite):

yo di

tú diste

él/ella/Ud. dio

nosotros dimos

vosotros disteis

ellos/ellas/Uds. dieron

So:

—¿Les diste dinero a los pobres?

Then, in the second sentence the first person answers that he previously gave them clothes and food.

So, according to the previous conjugation, in the first person we have:

—No, pero yo les di ropa y comida.

—¿Les diste dinero a los pobres?

—No, pero yo les di ropa y comida.
