Question

En otoño _________ viento.

Answer 1

Answer:

There is no context here, but I guess we must complete the sentence:

"En otoño _________ viento."

You can translate this to:"

In autumn _________ wind."

something that completes this is "there is a lot of" and then the sentence says that in autumn there is a lot of wind.

The translation of "there is a lot" can be "hay mucho", and then the complete sentence in Spanish would be:

En otoño hay mucho viento.

Answer 2

Hace viento I'm not sure, did the teacher gave the alternatives ?
