kpop1-8, Exercise 3: "Firsts" and language

Model answer:

BTS example: "the first act from South Korea to top the Billboard 200", with Love Yourself: Tear (2018). Boundary: South Korean acts; one US album chart; 2018. Owner: Billboard (as reported in the BTS article).
Blackpink example: "the first Asian act to headline Coachella in 2023". Boundary: Asian acts; one festival; 2023. Owner: the festival's billing (as reported in the Blackpink article). Note that the K-pop article words the same event as "first K-pop act to headline".

Language evidence (any two): English phrases in names, titles and lyrics, which have not guaranteed popularity in North America; fans learning Korean, often with romanization; trainees taught Mandarin, English and Japanese; the translation "Big brother is Gangnam style"; linguistic purity ideals still hard to alter.

Left out: the translator's role, because the articles I read said nothing about it and I did not want to write it from memory.
