"병이니?"

Translation: Is it a bottle?

[Rose.Melissa]

병 can also be translated as illness or disease. If the answer is "Is it a bottle?", "Is it an illness?" should not be marked as incorrect.

[Atcharya]

That's because Koreans have stopped using Hanja. This sentence, technically, can be rewritten as "瓶이니" or "病이니". Both answer should be accepted. By the way, we may use "疾病"(질병) to avoid confusion.

I did the same thing

[suhandiwiratama]

Damn... Yeah, I fell onto the same situation! "병이니?" also has the meaning of "Are you sick/ill?"

[Pamela909830]

Two years after your original post, I typed, "Is it a disease?" It is still marked wrong (Nov. 18, 2020). I did it again Dec. 19, 2020, and it is still marked wrong. I will report it again. It is still marked wrong July 12, 2021.

[E.Clues]

Exactly! How was I supposed to know they wanted a bottle and not an illness? :(

[Ana214213]

It would be easy if we say it while pointing towards the bottle( 이거) 병이니? or are you ill (너)병이니? . On the spot,Both in informal. right!
