"The teacher is going to answer the questions."
Translation:El maestro va a responder las preguntas.
Duo refused my answer: "La maestra va a contestar las preguntas." I don't understand why.
They underlined "responder" and said I used the wrong word, but "contestar" means "to answer" just as much as "responder" does.
It should be va a.
El maestro - The teacher
va a - is going to
responder - infinitive form of responder to answer
la preguntas - the questions.
