I'll bet the creator of that crossword is reading this thread and laughing his head off! Ok--I'll have to allow that maybe, in some languages, "neuter" is a gender, and that therefore 'it is gender' could be correct. But all my instinct is telling me that the s was meant to indicate possession, and the guy either is ignorant of the rule for 'it' (I wonder if he would think "The foal gamboled alongside its dam" was incorrect?), or he was being deliberately obfuscatory. Somehow I doubt the latter, unless it was designed for the elite of the elite. If it was intended for the general public, I would almost bet money that he intended for "it's" to mean "its": who in the world of the normal would delve so deeply into the use of an apostrophe?? This, I think, is a perfect ex. of what Wordwind was talking about in her 'responses that are actually correct get marked incorrect' post: most people don't sift for all possible meanings--they pick the most obvious one and go with it. But not everybody. Original thinkers (as one of his teachers described my son) often don't do well on tests. I notice this happens a lot in people of really high intellect.
