It’s that time of the year: We’re copyediting like mad. Colored pencils are flying across pages. Brian’s downing thermosfuls of coffee. Becky’s chain-eating Laffy Taffy because the sugar and constant jaw movement “help her concentrate.” Nicola’s using her eraser so furiously that a small cloud of rubber-scented dust hangs above her desk. Lisa complains that her body is becoming withered and atrophied from lack of sunlight and exercise, but we’ve noticed that her forearm muscles are getting totally ripped from lifting The Chicago Manual of Style so many times.

In the midst of our copyediting blitz, we’re pausing to let you, readers, sample the process. Submit your answers to the Chicago-inspired quiz below by clicking on the post’s title.
