taekwondo1-1, Exercise 2: Names, bodies and dates

Model answer:

Naming: from 1955 kwan leaders discussed a unified art; Choi Hong-hi advocated "Tae Kwon Do", the name closest to the pronunciation of taekkyon (before it, "Tang Soo Do" was the term for Korean karate).
First governing body: the Korea Tae Soo Do Association (later the Korea Taekwondo Association), established 1959; the article calls it the oldest governing body.
ITF: Choi broke with the KTA in 1966 and established the International Taekwon-Do Federation.

Dates that don't line up (any one): the article gives 1966 for the break and the ITF's founding, but also refers to the ITF's "1973 split with the KTA" and says South Korea withdrew its support for the ITF in 1972; or it says the ITF was founded in Canada, and later headquartered in Toronto. The article does not tie these together.
