@monmon Thank you for catching this lol I was scratching my head trying to figure this out

@BenDonnelly Sorry I am not a tutor and it's late but this is the way I saw it

The correct answer says:

"Unless Florida panthers acquire a larger habitat, their population will not be self-sustaining."

Self-Sustaining > Larger Habitat

Your logic would be correct if it said "If it got a larger habitat, it would be self sustaining"

(i.e Larger Habitat > Self-sustaining) (What if it only got a habitat enough for 10 panthers? What if poachers get the panther?)

For example:

Correct:

If I bought this car, then I made more money. (It is necessary that I made enough money for the car. The car is sufficient to prove this)

Mistaken Negation:

If I made more money, then I bought this car. (What if I only made $20? What if I don't even really wanna buy this car?)

So, if it's self-sustaining you necessarily have a habitat large enough.

@mdhrti I think you might have conflated universalizing with 'central'. 'Universal' here refers to a shared presence in cultures rather than making a value judgement (i.e how important it was).

It could very well be the case that ancient cultures cared a lot more about storytelling than modern cultures as nothing in the text explicitly refutes this. At least that is the way I saw it.

@MinjunJin i think you would have to remove, 'The store's competitors claim' as well
