To address the problem we will analyze each given statement and determine its truth value based on our understanding of the sets [tex]\(A\)[/tex], [tex]\(F\)[/tex], [tex]\(M\)[/tex], and [tex]\(W\)[/tex].

1. Paris [tex]\(\in F\)[/tex]:
- Paris is a city in France.
- Therefore, Paris belongs to the set [tex]\(F\)[/tex].
- This statement is true.
