I had a really big cup of coffee this morning!

Your answer to Marcos does not explain why a feminine version exists since, as you say, 'When we form a noun using the augmentative suffix -ón, the new word is always masculine, regardless of the gender of the originating noun. This is because nouns ending in -ón are generally masculine’.

This grading of this question appears to be an error on the part of Progress. Conditional Perfect is the answer specified, which is "no habríamos muerto" and is the answer that I provided  The answer from Progress is given as "no hubiéramos muerto" and is Preterito Plumamperfecto Subjuntivo, not Condicional Perfecto. 

In this sentence:  "Les lazo la pelota y deben apagarla con las dos manos."  

I throw you the ball, and you must stop it with two hands.

I don't understand the use of 'Les" is it referring to 'you"?

El concepto de antención plena

la llegada de la atención plena

Why is the article used in the second pharse but not in the first ?

It says, Además, me encantaría que mis alumnos desarrollen....

I was thinking it would say instead, Además me encantaría que mis alumnos desarrollaran...

Maybe I am overgeneralizing a concept or rule that isn't used here?

It appears from your examples that “se” is optional, although I don’t see that explicitly stated.  For example, “ Ayer me depilé las piernas.” doesn't have “se” in it.
