Assertion and Reason questions for Class 7 Chapter 8:

Assertion and reason questions are a type of question that tests the student's understanding of the concept. In each question, there is an assertion (statement) and a reason (explanation). The student needs to determine whether the assertion and reason are true and whether the reason justifies the assertion.

Example: Assertion: Plants are autotrophs.

Reason: They can make their food using sunlight, carbon dioxide, and water.

To solve this question, the student needs to check whether both the assertion and reason are true. If both are true, the student needs to check whether the reason justifies the assertion. In this case, both the assertion and reason are true, and the reason justifies the assertion. Therefore, the answer is true.

Steps to solve Assertion and Reason questions:

1. Read the assertion and reason carefully.
2. Check whether the assertion is true or false.
3. Check whether the reason is true or false.
4. Check whether the reason justifies the assertion.
5. If both the assertion and reason are true, and the reason justifies the assertion, the answer is true. Otherwise, the answer is false.

Tips for solving Assertion and Reason questions:

1. Read the question carefully.
2. Focus on the keywords in the assertion and reason.
3. Use your knowledge of the concept to determine whether the assertion and reason are true.
4. Use logic to determine whether the reason justifies the assertion.

Conclusion:

Assertion and Reason questions are an important part of exams. By following the steps and tips mentioned above, students can improve their chances of getting the correct answers. It is important to read the questions carefully and use logic to determine the answers. Students should also practice solving Assertion and Reason questions to improve their skills.
