Test question: How would you say "I haven't been in France for long."?

Per the lesson, Ne...pas + Présent indicatif + depuis longtemps = not long / not for long -> It started a short while ago, and is still ongoing

My answer marked incorrect: Je n'arrive pas en France depuis longtemps.

Correct answer per system: Je ne suis pas arrivé en France depuis longtemps.

According to the lesson,

use of Présent indicatif translates as "not long / not for a long time," whereas

use of Passé composé translates as "not for a long time / not for ages; over and done in the past"

Can somebody please explaine me the difference between 

échauffer

rechauffer

and chauffer

I cannot get it. Thank you

Is there a difference between "second" and "deuxieme"? Is "second tour" (and "deuxieme parti") just a fixed phrase?

Also, how can we tell when the adjective is supposed to go before the noun, e.g., "indiscutable montée" and "nombreuses similitudes"?

I am having trouble reconciling the 'correct' answer to the test question with the lesson. Specifically, below is the question and correct answer according to the program, but this use of 'attend un garçon' meaning 'expecting' does not seem to reflect the lesson. What do I have wrong?
