The intro says "Aunque, generally translated as although, even if, or despite of". I'm not sure there's any English construction "despite of", I think you may be conflating "despite" with "in spite of". As far as I can think of, these two phrases are used pretty interchangeably in English. 

Hello,

Can anyone please explain the use of ser in these 2 examples? Both are describing temporary states (I think.) They are from a video that has many sentences to translate..  This seems not to accord with the normal use of ser.

1. No sea tonto.  (I would tanslate this as "Don't act silly." We are not saying "You are a silly person."}
2. Era obvio que el conductor no había sido lo suficientemente cuidadoso.  (I don't think this is a passive construction. Shouln't this be "no había estado"?)

A question in the quiz said “estoy viendo un documental en la tele”. Why would this not be mirando en lugar de viendo?

The lesson says  "Remember that when you use this structure with an adjective, the adjective must agree with the subject." but none of the examples actually demonstrate this. It might be a good idea to throw in some feminine and plural adjective examples to more explicitly demonstrate the agreement!

Why is it wrong to put.   "No  tenía una casa"?    i.e  include "una"   in the translation of :  I didn't have a house.
