Explanation:

Bartoshuk zeroed in on the tongue's anatomy. She found that people have different numbers of fungiform papillae, with tongue topography ranging from, say, sparse cactus-pocked deserts to lush lawns. To qualify for superstardom, which is a genetically inherited trait, a person has to have wall-to-wall papillae on his or her tongue and also have an ability to readily taste PROP, a bitter synthetic compound also known as as 6-n-propylthiouracil, which is used as a thyroid medication.

dramatic irony occurs when the reader/audience knows more about a character's situation than the character does. the one main effect is that it gives the reader a sense of superiority, or detached superiority. the reader not only seemingly discovers what is revealed, but feels superior for doing so.
