A tropical flower would have a rich fragrance, hence the simile.
Context: "He had gotten close enough to her to trap her in a corner of her gallery, and he caught a whiff of her wonderfully rich fragrance." Claim: "He'd gotten near enough to her once, trapping her in a corner of her gallery, to catch a fragrance that smelled like an exotic tropical flower ."
Considering the context, is the claim true, false, or unknown?
