Read the excerpt from david foster wallace’s infinite jest. i have committed to crossing my legs i hope carefully, ankle on knee, hands together in the lap of my slacks. my fingers are mated into a mirrored series of what manifests, to me, as the letter x. the interview room’s other personnel include: the university’s director of composition, its varsity tennis coach, and academy prorector mr. a. delint. c. t. is beside me; the others sit, stand and stand, respectively, at the periphery of my focus. the tennis coach jingles pocket-change. based on this excerpt, which detail is implicit? a.  more chairs are needed to make seating available for all attendees. b.  hal is sitting in a chair with his ankle on his knee. c.  the director of composition is involved in the interview process. d.  the tennis coach has money in his front pocket.

A. More chairs are needed to make seating available for all attendees.

The other details noted are all stated explicitly in the excerpt. Hal, the narrator, says that he has crossed his legs, "ankle on knee." He specifically lists the Director of Composition and others as "the interview room's personnel." And he says explicitly that "the tennis coach jingles pocket-change."

The detail that is implicit--in other words, evident in the text but not overtly stated--is that the room is crowded without enough seating. The narrator is careful in crossing his legs--likely because of the crowded conditions. He also notes that others "sit, stand and stand," at the periphery around him.

Infinite Jest is a 1996 novel by David Foster Wallace, who also wrote non-fiction articles on tennis for Tennis magazine, as well as Harper's and Esquire.  The excerpt comes from "The Year of Glad," the first chapter in Infinite Jest.
