Using "their" as a genderless pronoun
Just a comment on their. It's actually not uncommon to see "their" used in logic problems as a singular non-gender pronoun. It is equivalent to saying "his or her" when the gender is unknown (and that is listed in some dictionary definitions). Putting a gendered pronoun (her or his) could lead to clues that let us eliminate all the male or female sounding names because "The 3rd person had peppermint for her first scoop."
