Why is there no preposition "de" after the verb "descend" in the phrase: "Elle descend les escaliers" ?

Hello, perhaps i missed this/am not understandng something: is there a rule for en versus de usage? eg une robe de satin or une robe en satin? 

Why does pronom relatif eliminates a subject complement.

Eg:J'ai rencontré par hasard une amie;je ne l'avais pas vu depuis mon enfance.

Hello,

I had this kwiziq question: Catherine ________ à l'hôtel ce soir. (Catherine is sleeping at the hotel tonight.)

I put the answer for the blank as "est en train de dort", but instead the answer is only "dort". I thought that "dort" would = he/she sleeps (not he/she is sleeping)

I thought that dormir = (to) sleep; être en train de dormir = sleeping.

Thanks for the help!

I'm reading https://www.lawlessfrench.com/grammar/plus/, and there's either an error or an ambiguity.  In the sections of plus used as a comparative or superlative adverb, it mentions liaising, but in the section for its use as a negative adverb, it says "In negative constructions, plus is always pronounced [ply]", with no mention of liaisons, which to me means that you should never liaise in the negative.  It gives the example of "Il n’est plus en France", which based on that rule, would mean you neither pronounce the S nor liaise it to "en".  I asked about that example on reddit, and several native French speakers said that liaising was optional, with some saying it depends whether formal or informal.  So, which is it?

Are all verbs strictly reflexive verbs or can they sometimes not be reflexive
