Nod, Ben and I have been struggling with this quiz all afternoon. It’s so very, very, very infuriating. My score is currently 23 / 72, although Nod’s on 37! Thanks to boingboing.net for the linkage, and note their proviso:
Consensus seems to be that #63 doesn’t work because the puzzle’s creators entered a typo. In addition to spelling, things like articles (“the xxx” vs. “xxx”) and punctuation (“xxx’s” vs. “xxxs”) matter – and aren’t always quite right. But other than that… it’s tough, and maddening.
