Thinking skills family and character

Thanks for this! Anyone having trouble with it, it's quite hard to explain but best way is to try putting a cross in the box when you find out some positive information and then the number of the clue which gave it for negative information (so you know it's not right and where you got that information from) e.g. 2. Die jüngste Person macht viele Witze- so put a cross in the box where the 7 and lustig meet then put a number 2 where 7 meet any other age/character) 5. Ein Junge ist fünfzehn Jahre alt - so put a number 5 where 15 meets with female family members. I got the answers as follows: Vater , Januar, launisch Mutter, Februar, nett Bruder, August, faul Schwester, Oktober, streng Halbbruder, 10 , intelligent Stiefbruder , 15, streng Cousine , 13, altmödisch Stiefschwester, 7, lustig
