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.
Answer:
—¿Les diste dinero a los pobres?
—No, pero yo les di ropa y comida.
