"Scientific names" make us think about the binomial nomenclature stated by Linnaeus for classification of living organisms, as some of the posed questions (eg. Homo sapiens. Equus ferus, etc), but not for others (eg. aurora borealis, clavicle, etc).
Furthermore, there is a lot of errors. Capsicum is only one genus of pepper (see Pimenta spp, Piper spp, etc) and not all Capsicum species are known as pepper. Equus quagga isn´t the zebra itself (Equus zebra) but an extinct type of animal that resembles a zebra (Vernacular name: Mountain zebra). Lots of corrections must be done! But the idea of the quizz is cool!
