find out who the thief is/math

for math we had to work out who the thief was.We had to find the thief who stole the ginger breed houses we had to work out four questions before we new who it was.On the first question we found that the person was wearing a sweater the second was that its a female so after thos questions i new to cross out the people who weren't wearing a sweater and all the people who weren't female.On the last two question we had to figure out another sentence and after that we new that it was not a visitor and on the fourth i found out who it was i think it is Irena Vicks.
