Answer:
Paul,
(grow up, obey) your grandmother!
Explanation:
I didn't know if you wanted me to translate but here it is.
Bonjour,
tu feras, pourras, enverras
Marc viendra, sera, apercevra
nous aurons, devrons, ferons
vous recevrez, tiendrez, irez
elles voudront, feront, seront
je deviendrai, pourrai, enverrai
elle ira, aura, voudra
The answer would be De la. I am not a native French speaker but in English the phrase translates from “Est-ce que tu veux de ia dessert?” To “Do you want dessert?”
