Spanish language Q&A Forum

The test question "I always wanted to be a dentist." I answered "he querido" but correct answer was "quise" 

Isn't that a past action that continues into the present? - perfecto?

Anyway this particular topic seems to be all over the place. The goal of these questions shouldn't be trickery IMHO. We're learning to speak a language - not to be a textbook scholar - or at least that's my goal. I asked one of the many Spanish speakers where I work what they thought and they said "it could be either and I'd understand you."

Cuales son los diferente tipos de fauna que se encuentran en el pantanal 

son peligrosas o inofensivas ?

dependiendo de el país la flora cambiará en el pantanal?

De quién was an option for this question: 

Mi perro, ________ me acuerdo a menudo, ha muerto recientemente.

However when I selected it I was marked wrong.

However according to this page

Using preposition a and de + el que, la que, los que, las que = to/of/from/about which/who (relative pronouns)

Should I have been marked right because quién doesn't necessarily need to pair with a lo/la?

In the quiz, the sentence was "When I go to Spain, I always go to the beach".  - "___________ voy a Espana, siempre voy a la playa"

The answer is "Cuando" without an accent.  In the lesson, it says that cuando without an accent is a relative adverb which introduces a depennt clause.  In the above example, what is the dependent clause that "cuando" is introducing?  I am not a gramarian, but it seems like both of the above clauses are independent.  That may be incorrect, but could you please explain?
