I'm on my cellphone. When I turn the phone sideways, and the screen turns, the word humanity appears. I don't know if this happens with other questions...
This is one of the very few occasions where the speaker stresses the wrong syllable: He says "interNACia" instead of "internacIa". Especially if the penultimate syllable is just an "i" followed by a single vokal, it appears to be tempting to stress the third to last syllable, but we are supposed to learn Esperanto here, not Ido.
I feel that ‘personoj’ would be more appropriate, since ‘human’ is a more literal and specific term, sort a ex.: person/people, human/humans\mankind\humankind distinction. But I’m just ~mid level-advanced beginner and those were just my thoughts
