FAQs on PPT: Syllogism - Verbal Ability & Reading Comprehension (VARC) - CAT

1. What is a syllogism?
Ans. A syllogism is a form of reasoning in which a conclusion is drawn from two premises. It consists of a major premise, a minor premise, and a conclusion, typically structured in a way that if the premises are true, the conclusion must also be true.
2. How do you identify the major and minor premises in a syllogism?
Ans. The major premise contains the universal statement, usually involving a general category. The minor premise typically includes a specific case related to the major premise. For example, in the syllogism "All humans are mortal (major premise). Socrates is a human (minor premise). Therefore, Socrates is mortal (conclusion)," "All humans are mortal" is the major premise, and "Socrates is a human" is the minor premise.
3. Can you provide an example of a syllogism?
Ans. Certainly! An example of a syllogism is: "All birds have feathers (major premise). A sparrow is a bird (minor premise). Therefore, a sparrow has feathers (conclusion)." This structure clearly shows how the conclusion follows logically from the two premises.
4. Why are syllogisms important in logic and reasoning?
Ans. Syllogisms are important because they provide a clear framework for logical reasoning. They help individuals analyze arguments, identify valid conclusions, and enhance critical thinking skills. Understanding syllogisms is fundamental in fields like philosophy, mathematics, and computer science.
5. What are common mistakes to avoid when constructing syllogisms?
Ans. Common mistakes include using ambiguous terms, making invalid assumptions, or presenting premises that do not logically lead to the conclusion. It's essential to ensure that the premises are clear and that the conclusion follows logically from them to avoid fallacies in reasoning.
