The correct option is B - 2 only.
[as per provisional answerkey]Why this is correct
The passage explicitly states that HMPV and SARS-CoV-2 belong to "two very different virus families" with "fundamentally different characteristics and epidemiology." It further highlights that they cause different levels of symptom severity, affect different population segments, and have different long-term impacts (HMPV being milder with no long-term symptoms, unlike SARS-CoV-2). Conclusion 2 logically follows from these premises: because their biological characteristics, epidemiological patterns, and clinical impacts are fundamentally different, the public health response and medical management (how they are "dealt with") should not be identical. The passage provides a comparative analysis specifically to highlight these distinctions.
Why the other options are incorrect
- Conclusion 1 - SARS-CoV-2 and HMPV are similar viruses: This statement contradicts the passage, which explicitly states they belong to "two very different virus families" and have "fundamentally different characteristics." While the passage mentions SARS-CoV-2 was novel, it does not support the claim that the two viruses are "similar."
- Option (a) - 1 only: This is incorrect because Conclusion 1 contains a factual inaccuracy based on the text (claiming similarity where the text states they are different).
- Option (c) - Both 1 and 2: This is incorrect because, while Conclusion 2 is valid, Conclusion 1 is invalidated by the passage's emphasis on the fundamental differences between the two viruses.
- Option (d) - Neither 1 nor 2: This is incorrect because Conclusion 2 is a valid logical inference derived from the stark contrasts in epidemiology and severity described in the text.
Key Concept
This question tests the ability to identify explicit contradictions and valid logical inferences by comparing specific attributes (novelty, family, seasonality, and severity) of two subjects mentioned in a passage.
