Loss By Compression (Solution)

by Charles Steinhardt and Rob Speer

A single letter can be inserted into each clue phrase, printer's devilry style, to produce a new phrase. Many of the resulting clues are ambiguous, but you can fit them into the given enumeration if you remove the I's and O's (the "bits") corresponding to the removed letter.

All 26 clues have a different removed letter and therefore a different removed number in binary:

AA long distance (a)cross WIDE
BOr(b)its Jupiter IO
CUseless fa(c)ts TRIVIA
DLatin and Rin(d)ge are at the end of a local one HIGH SCHOOL
EClassical Greek ord(e)r IONIC

XNot comple(x); Ted Barrus can use it IDIOTPROOF
Y Original New (Y)orkers by a lakeONEIDA IROQUOIS
ZGravel was recommended by Jingo(z)ian at one NOMINATING CONVENTION

The title is similar, in that "Loss By Compression" is "Lossy Compression" with a "B" (OOIO) inserted.

Inserting the letter M makes the new clue phrase WITH MINUS ONE CHARGE, IODINE ION, and the solution to this clue containing IIOI is TRIIODIDE, the answer to the puzzle.
