Name: _______________________________    Date: ____ / ____ / ______
Each question gives you two or more statements about people, animals or objects. Every statement must be treated as certainly true, however unusual it seems, and your answer must be based only on what the statements actually say, never on outside knowledge, guesswork or what seems likely. Some questions ask you to order people or things (for example by age, height, speed or cost); others give you a rule and ask what must logically follow from it. Read every statement carefully before choosing one option from A to E. Only pick 'cannot tell' if the statements truly do not give enough information to be certain; do not choose it just because working out the answer takes several steps.
Worked example. Aiden is taller than Bea. Bea is taller than Chidi. Who is the shortest? A) Aiden B) Bea C) Chidi D) Cannot tell E) Aiden and Chidi are the same height Answer: C) Chidi. Combine the two statements into a single order: Aiden is taller than Bea, and Bea is taller than Chidi, so from tallest to shortest the order is Aiden, then Bea, then Chidi. Chidi is therefore the shortest. Because the chain is complete, 'cannot tell' is wrong, and no equal heights were mentioned, so option E is also wrong.
