Thanks Julia. I thought it was 42 hours and before I submitted the quiz I'd researched it quite well. We'd also been studying Romeo and Juliet at the time so it was fresh in my mind. But mistakes can happen and I'm glad this one has been cleared up.
And Ren, yes it is wonderful how much you learn here. I probably don't even realise how much knowledge I've gained from FT but there you go, it is a great site in many ways including educational and entertaining!
