Factual error: Zira puts the blocks together to form the stairs that will allow her to get the banana, but only stares at it. When the female scientist asks why she won't eat it, Zira says she loathes bananas. Bananas grow in tropical climates near the equator. New York City, where she lived in the future, is in a subtropical climate zone, and not grown there. How would she loathe bananas if she's never eaten one before?
Suggested correction: There is too much we don't know and too many possibilities to declare this a mistake. Perhaps they have trade with lands further to the south. Perhaps the climate has changed and land around New York is now hospitable to bananas. Perhaps in the two thousand years between our time and hers, a strain of bananas developed that thrives in temperate environments.
