Syllogism — Preparation

This question tests your understanding of Syllogism, a key topic in the Logical Reasoning section. The detailed solution above uses a step-by-step approach to show the reasoning, and where available, a shortcut that helps you solve similar questions in under 90 seconds during the actual exam.

Syllogism questions give two or more statements and ask which conclusions follow from them. You must accept the statements as true, even if they contradict real-world facts. This topic covers statements with "All", "Some" and "No", "only a few" type statements, and possibility conclusions such as "Some A can be B". The Venn diagram method is the most reliable approach. Draw every possible arrangement that satisfies the statements, and accept a conclusion only if it holds in every diagram. A possibility conclusion follows if it is true in at least one valid diagram. Knowing the standard rules, such as "All + All = All" and "Some + All = Some", speeds things up once you are confident with the diagrams. Practise the syllogism questions below. Each solution includes a Venn diagram.
