Sorry to be so 'flumpy', crosso. This is the 8th year running I have devised ths quiz, that's 400 questions to date, and I am running out of original inspiration. Lab News have borrowed my quiz this year - I don't get paid for it - and it's only a bit of fun.
However, do keep looking at question No. 36. I am betting that most people will get this wrong....
