Retype the sentence by placing the right verb and the right form of the verb: "Despues de clases yo (cantar/pintar) en el coro."

The answer is despues de classes yo Canto en el coro

Despues de clases yo canto en el coro.

Explanation: After classes I sing in chorus. Cantar is to sing and pintar is to paint in Spanish. I'm a native spanish speaker so i guarantee the answer is right. :)

corras is the only one that is informal but doesn't follow the suffix rule. correr is the verb. corre is the formal verb form. corra would be used as the formal is corre ended with an a.

your best bet would be corras, it's the only one that is informal but is still wrong
