I got this correct in the quiz b/c I followed the hint but I don't understand the use of Imperfecto over Indefinido here if there is a specific time period in the past identified. Why trabajaba rather than trabajo? (I know the hint says "used to" but the question still stands.) Thank you!

Hi,

I was wondering if there is a reason the "c" turns in a "j",  It seems to me that

conduce would sound fine in front of "e" and "i" (perhaps just a change in front of the "a" and "o".

Do you know of any reason for the change?

Thank you.

I don’t understand the use of present perfect in telling past events. 

Is there a reason why "and you can see advertising" translates as "es posible encontrar publicidad." Would "y [se] puede ver publicidad be acceptable? 

Am I right that I could exchage qué poco with cuánto and the sentence would be correct just with an opposite meaning?
