Thank you, mamya, for informing us about this.
I do wish people would be honest and not ask for help in these "official" charity quizzes.... or at least not so far ahead of the closing date.
Nexus warned of this recently and even posted a link saying that the setter of that particular quiz had requested that no entrants seek internet help and would prefer people to send in their own unaided work.
And yet still people ask for answers.....
