For a single individual, all of the above is true, but for a large enough sample size, the answers may be more generally useful because you account for all of those rounding errors.
No, because if my case holds more genera (and I suspect it does), the answers are in part out of sheer frustration, and therefore prone to being similar to the last one given.
I didn't exactly rage quit but did think it was silly.
I wouldn't describe teal as blue or green any more than I'd describe purple as red or blue, so being forced to pick felt silly. Like being forced to choose my seventh favorite Norwegian glacier - technically its a valid question but my answer is necessarily going to be arbitrary.
I am not afraid to say this is poorly designed.
