nouns

[artart]

1) Teachers work hard in France.
2) Teachers are well-paid in France.

3) People work hard in France.
4) People are well-paid in France.

Do these mean

a) All teachers/all people
b) Most teachers/most people
c) At least some teachers/at least some people

[violazoli]

I think, those sentences above mean that teachers/people work hard and are well-paid in France GENERALLY. So, the mentioned attributes are characteristic/typical for each of them. Because the nouns are in plural form, and they has no definite article ("the").
So, the answer is in short: a). All teachers/all people.

I would actually say b. Generally ≠ all. I suppose generally ≠ most, either, but it does at least imply "most," in my understanding of what "most" means.
