Similarly, descendre d'un escalator or descendre un escalator?

Can we say go up/go down 1 floor in French:

Monter/descendre un étage  

Thank you.

While reviewing, I came across this question...  "How best to say 'He loved this book!'?"     Since the question was multiple choice, the answer that it expected was obvious.   But isn't l'imparfait better suited for this example than passé composé? When someone "loves a book", it is not a brief, one time thing. They don't love the book and then forget about it the second they put it down. It is more likely that he loved the book for years, until he died. Or if he is still living, he continues to love this book. It just seems to me that an emotion is a rather bad question choice for passé composé.

Why does this sentence use "en" instead of "dans"?  I thought "You got into the car quickly" should be "Tu es monté dans la voiture rapidement."  Is there a difference in meaning or can I use "en" and "dans" interchangeably to express getting into a car?  

Is it absolutely wrong to use est-ce que to form a question using names? Thanks. 

"Qu'est-ce que c'est?" (what is that?) is one of the first things a beginner in French learns. Now that I am moving from A2 to B1, I learned that "Qu'est-ce que..." is the question form to use when the "what" is the object of the sentence. I think the verb "to be" is throwing me off. Could someone explain to me how "what" is the object of the sentence in question like "what is that?"
