What Are Assertion-Reasoning Questions?
Assertion-reasoning questions are higher-order thinking questions where students are presented with two statements:
Assertion (A): A fact or statement.
Reason (R): A statement that attempts to explain the assertion.
Students are then required to determine the correct relationship between the two.
The answer usually has four options:
Both A and R are true, and R is the correct explanation of A.
Both A and R are true, but R is not the correct explanation of A.
A is true, but R is false.
A is false, but R is true.
These questions test concept clarity, analytical thinking, and reasoning ability—skills that go beyond rote learning.
