Dear Ben Tausig and his proofreaders,

This was a test, right? To see if we’re paying attention? The answers to this week’s Inkwell [“Super Groups,” April 8] are in the Reader from last week [April 1] and the answers to “Deductive Reasoning” [March 25], which should have been in April 1’s issue, are MIA.
