I know "male, female, FTM, MTF, other" is a standard gender/sex question, but I don't know why. A problem is that it implies that "FTM" is a distinct category from, rather than a subset of, "male" (ditto for female). This would be better if other questions had answers that were subsets of other answers, but you seem to try hard not to do that. This could be fixed by phrasing it as "cis male", but then you'd get people complaining about "cis" and "trans" not being a perfect dichotomy and complaining about the confusing word and so on. This could also be fixed by splitting the question into "gender (male/female/other)" and "Are you trans? (yes/no)", but then you'd get other complaints.

I wouldn't have been too far off on the Newton question if I had been able to remember the mapping between century numbering and year numbering. I ended up two centuries off. Fortunately I took that into account when calibrating.

Also, for the record: I'm not "considering cryonics". I'm cryocrastinating. Cryonics is obviously the best choice, and I should be signing up for it in the next five seconds. I will probably die while not signed up for cryonics, and that will be death by stupidity, and you will all get to point and laugh at my corpse.
