In the example below, why is it 'aprovechó' and not 'se aprovechó de'? It seems quite a negative context to me, and the context even seems to be leading us towards using the reflexive form by saying 'el muy egoísta'. 

Rafa, [being] such an idiot, took advantage of the moment to break up with me. : Rafa, el muy egoísta, ___ la ocasión para romper conmigo.

In the last section of the translation, "between the practical, incredulity and mysticism" is translated as "entre lo práctico, la incredulidad y el misticismo."  I don't understand why the práctico gets lo as it's article (other than because the hint said so).  Can you explain, please.  Thanks

1. Qué música te gusta más?

What music do you like the most?

2. Cuál universidad es mejor?

Which university is better?

Is Qué + noun used when the universe to chose from is large?

Is Cuál + noun used when the universe to chose from is small?

Would you say Cuál universidad es más mejor or Qué universidad es más mejor?

Which university is the best?

As an extremely well-educated native North American speaker trying to learn Latin American Spanish, I find the semantics in this lesson frustrating. This is punctuated by all the comments seen here. There is insufficient context provided. For example (ignoring the hint since hints aren't given in real life), one of the quiz questions asks to translate: "They are having ice cream." I would immediately think "Están tomando helado." - or perhaps "desfrutando" given some of the loose lesson translations. However, to think: "Van a tomar helado." I need further context. For example: "They are having ice cream this afternoon." - "Van a tomar helado esta tarde." Otherwise in English you are much less ambivalent saying: "They are going to have ice cream." I understand both sides of the arguments and I fall more on the side of "They are going to have," but a better solution is to provide a more complete explanation and context in the lesson, after all, it is more common to say "They are going to have." Concede that we use the exact same literal expression in both Spanish and English but then take it further in the lesson to explain the nuanced differences in English thought compared to Spanish thought. 

Dicha ejemplo, eso es, " Nos costo mucho" = It was difficult, la significa del  verbo COSTARSE en este contexto = i find it hard to/ difficult to in the sense of speaking to someone...... Esta razon.

   BARRY.

Here we learn 'estar por llover'

It's only a couple of weeks since I learned 'estar para llover' and I can't tell the difference.
