I did not write quotation marks and my answer was not accepted. It is very strange. I reported it.
yes this is the only time punctuation has been taken into account to give a 'wrong' answer. Inconsistent
There is no option to report "my answer should be accepted", which I guess is the reason this is still not corrected.
I also left out the quotes and my answer was considered wrong.
i agree with the comments below regarding the fussiness about quotation marks.
