"The worker wears a black pair of pants."
Translation:Pekerja itu memakai celana hitam.
'the worker wears a pair of black pants' or simply 'the worker wears black pants'.
Both translations are accepted when translating from the Indonesian sentence to English (I just updated it).
It's just that I don't want to change the original English sentence at this moment, because I'm not sure what the consequences are for the skill and the course.
