I don't think it matches any string at all; it seems too specific for that.

I remember practicing a similar question, and I think it only matches floats without thousand separators.

I think this regex is about matching numbers, but I'm not sure if it includes thousand separators or not.

I'm a bit confused; I thought it could match integers too, but I guess it has to be a float because of the decimal part.

Hmm, I'm not sure about this one. The question mentions they're working from conjecture and opinion, not data. Maybe we should consider doing some kind of value analysis to evaluate the options more objectively?

This is a classic exam question - they're trying to trip us up with the wording. I'll need to read each statement closely and really think about whether it's true or not. Can't afford to rush through this one.

I feel uncertain about the FDA classification—like, do all generics need to prove their effectiveness in the same way as brand-name drugs?
