# "How to Use Assertion and Reason in Logical Reasoning: Examples and Multiple Choice Questions"

Assertion and Reason questions present a statement (assertion) followed by a reason for that statement. You need to determine if both the assertion and reason are true and if the reason correctly explains the assertion.

Explanation:

1.Assertion: A statement presented as true.

Reason: A statement that explains the assertion.

Objective: To evaluate whether the assertion and reason are true and if the reason explains the assertion.

Examples:

2. Assertion: The sun rises in the east.

Reason: The Earth rotates from west to east.

Explanation: Both the assertion and reason are true, and the reason correctly explains the assertion.

3. Assertion: All mammals lay eggs.

Reason: Mammals are warm-blooded animals.

Explanation: The assertion is false, so the reason does not correctly explain it.

Multiple Choice Questions:

1. Assertion: Water boils at 100 degrees Celsius at sea level.

Reason: Heat energy is required to break the hydrogen bonds in water molecules.

A) Both Assertion and Reason are true, and Reason is the correct explanation of Assertion.

B) Both Assertion and Reason are true, but Reason is not the correct explanation of Assertion.

C) Assertion is true, but Reason is false.

D) Assertion is false, but Reason is true.

Answer: A) Both Assertion and Reason are true, and Reason is the correct explanation of Assertion.

2. Assertion: Plants perform photosynthesis.

Reason: Photosynthesis is the process by which plants convert sunlight into energy.

A) Both Assertion and Reason are true, and Reason is the correct explanation of Assertion.

B) Both Assertion and Reason are true, but Reason is not the correct explanation of Assertion.

C) Assertion is true, but Reason is false.

D) Assertion is false, but Reason is true.

Answer: A) Both Assertion and Reason are true, and Reason is the correct explanation of Assertion.

3. Assertion: The moon revolves around the Earth.

Reason: The gravitational force between the Earth and the moon keeps the moon in orbit.

A) Both Assertion and Reason are true, and Reason is the correct explanation of Assertion.

B) Both Assertion and Reason are true, but Reason is not the correct explanation of Assertion.

C) Assertion is true, but Reason is false.

D) Assertion is false, but Reason is true.

Answer: A) Both Assertion and Reason are true, and Reason is the correct explanation of Assertion.

4. Assertion: Oxygen is essential for respiration.

Reason: Oxygen is used by cells to produce energy in the form of ATP.

A) Both Assertion and Reason are true, and Reason is the correct explanation of Assertion.

B) Both Assertion and Reason are true, but Reason is not the correct explanation of Assertion.

C) Assertion is true, but Reason is false.

D) Assertion is false, but Reason is true.

Answer: A) Both Assertion and Reason are true, and Reason is the correct explanation of Assertion.

5. Assertion: Metals are good conductors of electricity.

Reason: Metals have free electrons that can move easily.

A) Both Assertion and Reason are true, and Reason is the correct explanation of Assertion.

B) Both Assertion and Reason are true, but Reason is not the correct explanation of Assertion.

C) Assertion is true, but Reason is false.

D) Assertion is false, but Reason is true.

Answer: A) Both Assertion and Reason are true, and Reason is the correct explanation of Assertion.
