My apologies for having multiple questions on this lesson. It is not that the lesson is unclear. It is that the two test questions that test the understanding of the lesson are awkward if not downright counter productive to reinforcing the lesson.
For example: the lesson states that when 'avoir + descendu' is used with an animated being as the object then it means to kill/shoot that being. Unless the test question really means that Jack took the giant's dead body(and hence no longer animated (LOL) ) downstairs then it is misleading and confusing. In English "to take someone downstairs" simply means to usher them to your basement.
