Hello! Continuing on with FSI French lesson 7, and I'm doing practice drill A-14 (c'est vs. il est). It's hard for me to understand why some of them use il est, and some use c'est. I've seen some explanations for this and have looked it up in grammar books, but I'm still not sure. Here is an example: Allez-vous acheter l'auto de Roger? Non, elle est trop chere. Avez-vous une bonne? Non, c'est trop cher. As far as I can tell, if it is referencing something specific, such as Roger's car (rather than simply a car), then you would use il/elle est. Another example with elle est is cette chemise, which again would be specific to that shirt. If it is something more general (a maid, not a specific maid), then it is c'est. Another example with c'est is un taxi. If it was ce taxi, then my understanding would be to use il est. Is that correct? Thanks!
