Grade 8 · New Jersey standards

The library door has locked behind you.

Five doors, five pieces of English between you and the corridor: a word you do not know, a sentence somebody has punctuated badly, a claim that needs the right quotation, an argument with a hole in it, and a story with a point.

A wrong answer gets you a hint. A second one gets you the reasoning and opens the door anyway.

Each door draws from a larger set, so a second run is a different five.
