AIIMS 2003 Zoology Viral Diseases Assertion Reason Question

To analyze the question regarding the Assertion and Reason related to Severe Acute Respiratory Syndrome (SARS), we need to evaluate both statements and their relationship.

Assertion Analysis

Assertion: Severe Acute Respiratory Syndrome (SARS) originated in China.

This statement is true. SARS is caused by the SARS coronavirus (SARS-CoV) and was first identified in the Guangdong province of China in November 2002. The outbreak led to global transmission, but its origin is indeed traced back to this region.

Reason Analysis

Reason: China is the most populated country in the world.

This statement is also true. As of the latest data, China has a population exceeding 1.4 billion, making it the most populous country globally.

Relationship Between Assertion and Reason

Now, we need to assess whether the Reason provides a correct explanation for the Assertion. While it is true that SARS originated in China and that China is the most populated country, the population size does not causally explain the origin of the virus. The emergence of viruses is influenced by various factors including environmental conditions, human behaviors, and wildlife interactions rather than merely the population size of a country.

Conclusion

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

Why Other Options Are Incorrect

• Option A: This option states that both the Assertion and Reason are true and that the Reason is the correct explanation of the Assertion. This is incorrect because, while both statements are true, the population size does not explain why SARS originated in China.

• Option C: This option claims that the Assertion is true but the Reason is false. This is incorrect since both statements are true.

• Option D: This option states that both Assertion and Reason are false. This is incorrect as both statements are confirmed to be true.

Summary

In summary, the Assertion is factually accurate regarding the origin of SARS, and the Reason is also a true statement about China’s population. However, the Reason does not provide a genuine explanation for the Assertion, leading us to select Option B as the correct answer.
