According to the Guardian article, why was world music originally created as a genre? $($Choose one.$)$

The genre was a marketing term created in the $1980$s by record labels to categorize newly popular world styles, particularly African music.

The genre was intentionally created to avoid letting music of other cultures into the mainstream.

The genre was a vague marketing term that was going to be built upon later, but then the labels abandoned the plan.

The genre was created to compel performers of world styles to adopt a more Western sound.
