Spanish language Q&A Forum

As someone else pointed out this is a bad translation of English. In English it would be said that, "It's a good thing I left Miguel!" I don't buy the British translation that was proposed as I have literally never heard that. 

In the test the question is "Coloca las plantas _____ sol." I understand that "al" is the correct answer as far as a contraction, but why do you use "a" in this instance? Why is it not "en el sol"?

First of all, how to decide when to use despertar and when despertarse?

Second question, why can't we use levantarse in place of despertarse?

It appears to me that the better answer for "we have been" would be "hemos estado" rather than "hemos ido," which seems to me to say "we have gone."  In English, there is a difference between "been" and "gone."  Could you please advise.  Thank you.

There was a question in one of the quizzes I took and it led me to this grammar topic (questions with qué):

Which flowers do you prefer?  

¿ _____ flores prefieres ? 

I put cuales in the blank, but was marked wrong, it said the answer was qué. 

I went to the lesson on cual/cuales (interrogative pronouns) and there was a sample sentence referring to flowers, using cuales prefieres.  

In the English translation to the quiz it uses which and I assumed that a select few flowers were being referred to, thus the answer should be cuales. It is a bit ambiguous.
