Mank, oil, pew, or IQ?
What is special (very special) about this sentence?
Don't be distracted by the literal meaning of the words; that's completely irrelevant.
when taken as values 1-26, modulo 10, give the digits of pi.
(Mank oil pew or iq) gives (13,1,14,11, 15,9,12, 16,5,23, 15,18, 9,17), for 3[.]1415926535897.
Next would be
9323, with the options of [is][cmw][blv][cmw], so we're kind of stuck. I haven't checked to see whether other choices earlier might let this go on longer, but it looks like the most we could do to extend this (without backtracking) is replace "IQ" with "IQs".
