Syllogisms - Frequently Asked Questions

A syllogism is two premises followed by a conclusion. The conclusion is valid only if it necessarily follows from the premises — like "All A are B" and "All B are C" therefore "All A are C".

Each syllogism is worth 100 points for a maximum of 1000. Watch out for conclusions that seem true in the real world but do not follow from the premises.

Syllogisms test pure deduction: separating what must be true from what might be true. It is a core component of cognitive and managerial assessment.
