청각 = 聽覺
Why not 하라바지의 청각이 나빠 ?
There's some inconsistency with the answers. For example, 청각 requires "hearing" but other times it's "sense of hearing" or "sense of X"
If the English translation isn't correct, just report it.
What's wrong with "Grandfather has a bad hearing.?"
why is literal translation not accepted? this is very inconsistent
