Thanks. I got them all except the first one and the penultimate one - neither of which, it seems to me have anything to do with science. Certainly not Zodiac signs which are bunkum. Could you not change then for a couple of genuine science questions?

Thank you for your comment. However, I’m not sure which questions you’re referring to (since the questions are randomly selected from a database of 200). Also, I prefer to keep the questions about Zodiac signs (after all, there has to be something for everyone) ! 😉
