The lesson says that when talking about specifics, you use être, but the kwiz said this should be aller:

Martine était malade, mais elle ________ mieux à présent.

She is feeling better at present sounds like it is specific, so why is 'est' not right here?

…is not an acceptable alternative to ‘c’est n’importe quoi’ if you don’t know in advance what the idea behind this question is?

In the Charles Aznavour song it's "On a tort de penser, je sais bien, aux lendemains". I'm confused by the lendemains as it is in the present tense and referring to the future. Why that word? Is this how one would say "tomorrows" in a poetic sense, referring to the future in a boader sense vs. just "tomorrow" as in the day after tomorrow. Could you replace lendemains with something else and still have it make sense?
