Hola A

Reading exercises are for both European and Latin American Spanish focus. What you won't and shouldn't find if you are doing LatAm is any question using "vosotros" or anything grammatically related to this pronoun. In Writing challenge exercises and dictations we adapt the sentences/words that are specific for LatAm or Spain, so you come across more specific vocabulary within your chosen focus. 

I hope this clarified it.

Saludos
