I always learnt that: " I went up the ladder was" took the verb "être"

Je suis allée jusqu'a l'echelle

Why is it in your example with "avoir". "I went up the stairs"

"J'ai monté les escaliers"??

This part of the lesson is really messing with my learning process. Please answer me this....In the example, "Tu manques à Lise", IS it or IS IT NOT "Lise misses you."  ???

It would seem "Qu'ont fait les hommes" is an accepted sentence. According to the logic of this article, it should be "Que les hommes ont-ils fait." Can anyone explain this difference? Is one of these wrong? Is there some exception for "que?"
