You copied the answer from somebody else or did the calculation yourself?
If the last, why not to reproduce the calculation yourself?
Are you being serious?
You'd like to think so - and if you didn't, then you'd be marked wrong. However, for many decades (long before Internet) there have been questions out there that are completely and utterly wrong, and NONE of the answers have been correct.I think I answered this. I went with the answer that was closest to what I did get. But, I am assuming that I should have gotten one of the answers listed.
