I had a similar question on an exam; the question was "is a 4/10 on the pain scale subjective or objective". I said subjective, and I got it wrong. My professor told me that normally pain would be subjective, but, because they assigned a scale to it, a 4/10 becomes objective. I disagree with this, because a 4/10 could mean 10 different things for 10 different people, but oh well.
