"Do you need to take medication'' was marked wrong. In fact ''medicine'' is a field of knowledge, for example ''the university has a faculty of medicine''. ''Medicine'' can be colloquially used to mean ''medication''. So they should accept both.
Agree. I reported. I am a Chinese Medicine practitioner and those characters obviously can be translated as "medicine" and "medication" because the words are synonymous in spoken English (at least here in the US).
