Thanks for your suggestions. This quiz generally does not count uninhabited overseas territories, so Heard Island and McDonald Islands are not included. For Panama's six indigenous regions, it appears that two belong to second-level subdivisions rather than first-level. I have adopted the suggestions regarding Burkina Faso, Iceland, and Trinidad and Tobago, and made several other changes in reference to the ISO website.
Burkina Faso: 现在有17个区
Ethiopia: 现在有12个region
Iceland: 现在只有61个municipalities了
Panama: Region 指原住民吗?好像应该有6个
Trininda and Tobago: 有不少不同版本的划分 5个 Municipality 可能分为 2个 city 和 3-5个 borough,可能还有一个ward
Tuvalu和Mauritius 可能也有不同的划分法。
很多国家好像有本地语言翻译成英文对应的词有不准确的情况,要不要参考一下iso-3166的标准?
