Assertion and Reason


Introduction

  • This type of reasoning questions consists of two statements; an assertion (statement of fact) and a reason (explanation for the assertion). You have to determine whether each statement is correct. If both the statements are correct, you have to determine whether the reason supports the assertion. There will be four answer choices for the possible outcomes and you have to select the correct one.

  1. Assertion: A simple statement
  2. Reason: Reason is the explanation for the assertion.

Examples

    B. If both assertion and reason are true but reason is not a correct explanation of assertion.
    C. If assertion is true and reason is false.
    D. If both assertion and reason are false.
