"African" "Amerindian" "Malayo-Polynesian", and "Japanese/Korean" are not language families. I don't know what your source for these was, but it's incorrect. There's more than nine major families in existence, so I think you should change the question all together. I have a linguistics degree and couldn't make sense of what you wanted for the question. If you're going to divide them this way, you need to accept type ins. If you want to keep it "African" you should accept "niger-congo" and "nilo-saharan", for Amerindian I suggest adding "Oto-Manguean" "Tupian" "Arawakan" as type in answers. You should completely change Malayo to Austronesian and remove "Japanese Korean," which are each their own families and not an over arching category of linguistic branches, and replace it with maybe Astroasiatic.
I'm getting this from a Merriam-Webster's atlas. Korean is not a family but a single language. Japanese shares "Japonic" with Ryukuan, I have accepted that as a type in. Ameridindian, I know, is a pretty wide category, but I'm trying not to make this too hard, same with African. Malayo-Polyenesian, I would consider a solid family, but I have accepted Austronesian as an answer. Thank you for your insight.
Ural-Asiatic isn't accepted by most modern linguistics (even Altaic is controversial at best), Malayo-Polynesian is a subgroup of Austronesian, Korean is a language isolate, Japanese is a Japonic language, and the African and Amerindian "language families" are so incorrect that I can't even begin to explain it. You're putting Arabic (and presumably Hebrew, Aramaic, and the like), Wolof, Amharic, and ǃXóõ in the same family, and likewise for Aleut, Quechua, Mayan, and Anishinaabe, both of which are beyond untenable.
If you were dead set on nine language families, it would make much more sense to just take the nine largest by number of speakers (Indo-European, Sino-Tibetan, Niger-Congo, Afro-Asiatic, Austronesian, Dravidian, Altaic, Japanese, and Austro-Asiatic) or number of languages (Niger-Congo, Autronesian, Indo-European, Sino-Tibetan, Afroasiatic, Trans-New Guinea, Pama–Nyungan, Oto-Manguean, and Austroasiatic).
The list of street types seems pretty arbitrary. Why does it have those, but not crescent, parade or gate? Is it perhaps a list of the ten that are most common in a particular city or country?
Thank you.
And since when are all African languages a single family?
This part of the quiz is ALL wrong, sorry.
Here's a suggestion: try branches of indo-european languages.
