Read the excerpt from 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.

Which phrase or sentence is the best example of unusual language?

ankle on knee, hands together in the lap

The interview room’s other personnel include

the others sit, stand and stand, respectively

The tennis coach jingles pocket-change.

"ankle on knee, hands together in the lap "

Explanation:

Simply put, an unusual language can be the type of language that is not normally used in a conversation or speech. It can be a weird way of saying things or even a different structuring of the words in a sentence that seems to mean something other than the intended one.

From the given excerpt of David Foster Wallace's "Infinite Jest", the example of an unusual language is the use of the words "ankle on knee, together in the lap". This sounds weird in itself, considering the sentence frame. How can the ankle be on the knee and both hands together in the lap? But though it sounds weird, it is just the description of how the character was sitting in front of the others.

Thus, the correct answer is the first option.

the following key ideas correctly express the key sentence.

restate key idea: most people can learn to swim in ten short lessons.

restate key idea: the majority of water-accident victims require mouth-to-mouth breathing.

restate key idea: an empty, tightly closed gallon jug will support a tired swimmer.  

restate key idea: first aid is to prevent accidents as well as assist in rescue.

explanation: the key idea needs to have the same topic as the key sentence (drowning and safety).
