Why is it "El cartero pasa todos los días a las tres de la tarde" instead of ""El cartero pasa todos los días a las tres por la tarde"? I thought we learned that it should be en, a, or por to express a specific time of the day? 

Que tal,

How interchangeable are tras and detrás? Is one preferred over another, and if so, does it vary by country or age or context?

I'm think about basic use meaning 'behind,' such as "El niño se escondía tras (detrás) las cortinas."

Thanks!

The test asked to translate "I like white wine" to Spanish, but indicated "Me gusta el vino blanco" was the correct answer. The English sentence seemed unspecific to me, as though the speaker was making a general statement about a category of wine they liked. To add an article seems to imply the speaker likes a specific kind of wine ("I like the white wine"). Is this the same implication in Spanish? Could one say "me gusta vino blanco"? Or is an article always required, and unspecific preferences would require "un/una"?

Thank you.

Select the option with the verb in the correct form of the imperfect tense.

I would translate quería as I wanted or was wanting.  Thank you.
