To read the "B6/6b/2a/C1/10a 5a/A6/9b 7a B2/D2", if the pair starts with a letter, it's a Band answer; if it starts with a number, it's a Row answer. Take the nth word appearing in order in the Band answer, or the first or second word ("a" or "b") in each Row answer. The answers taken in order are LLULL/ALLIUM/TIBETAN/INGA/NUEVO FUNYUN/OBOL/RULA ILIAC ANGELENO/MARLBORO. Reading the initial letters of each word forms "LATIN FOR I AM," which is SUM, the answer.
