The first thirteen letters of the English alphabet are written out in reverse order, and the remaining thirteen are left standing as they are. In the row so formed, which letter is eighth from the left end?

Reversing A to M gives M, L, K, J, I, H, G, F, E, D, C, B, A, and N to Z follow unchanged. Counting eight along the new row — M, L, K, J, I, H, G, F — lands on F. In the untouched alphabet the eighth letter is H, so H is what you get by forgetting the reversal; G and E stand seventh and ninth in the new row, so either follows from a count that is one short or one long.
