Just so you all know, the answer choices are:

B) because of the speed limit

C) because of the heavy traffic

D) because of short daylight hours

I believe it's A) distance

¡hola!

i don't know how many words are missing

es verdad que acá en el mes de septiembre.

means

so i guess it's ►

es verdad que el verano termina acá en el mes de septiembre.

it's true that summer ends here in september.
