Assertion and Reason

Assertion and Reason :

According to the dictionary. Assertion refers to stating or claiming something forcefully and that the Reason is a fact. Here, we shall deal with the combinations of assertion and reason and relate with each other in order to find their correct syncing.

An assertion is an affirmation, a declaration or a strong statement. Normally assertions have reasons. In this question type, an assertion is first given followed by a reason. You are supposed to first judge whether the assertion (A) is true and then decide on whether the reason (R) is true and in case both A and Rare true, then we need to see whether the reason is the correct explanation of the assertion. The following solved illustrations will help you to get a clear understanding of the question-type.

Directions : In each of the illustrations, there are two statements labelled as Assertion (A) and Reason (R).

Give answer

(a) if both A and R are true and R is the correct explanation of A

(b) if both A and R are true but R is not the correct explanation of A

(d) it A is false but R is true

(e) Both A and R are false

This topic is meant to judge the candidate's knowledge and also determine his/her ability to reason out correctly. This is an important feature of critical or logical reasoning and it indirectly holds its importance for all important exams.
