Which of the following statements reflect the logical and rational inferences that can be drawn from the passage about SARS-CoV-2 and HMPV?
1. HMPV has, historically, had longer documentation of studies when compared with SARS-CoV-2.
2. The two viruses are different from each other and this results in markedly different outcomes amongst those affected.
3. Long-term impacts of the two viruses are dissimilar and this is an important differentiator between them.
4. One of the common factors between the two viruses is seasonal specificity.

Question

Which of the following statements reflect the logical and rational inferences that can be drawn from the passage about SARS-CoV-2 and HMPV?
1. HMPV has, historically, had longer documentation of studies when compared with SARS-CoV-2.
2. The two viruses are different from each other and this results in markedly different outcomes amongst those affected.
3. Long-term impacts of the two viruses are dissimilar and this is an important differentiator between them.
4. One of the common factors between the two viruses is seasonal specificity.

Select the answer using the code given below.

Accepted Answer

Correct Option: (b) 1, 2 and 3 Statement 1 is correct because the passage states that people have been exposed to HMPV for decades and the virus is well-studied, implying longer documentation compared to the novel SARS-CoV-2. Statement 2 is correct as the text notes they belong to different families with fundamentally different characteristics and epidemiology. Statement 3 is correct because the passage explicitly points out that both viruses cause different severity of symptoms over the long term. Statement 4 is incorrect because the passage states that strong seasonality is seen in HMPV, unlike SARS-CoV-2 (meaning SARS-CoV-2 lacks this seasonality). Thus, statements 1, 2, and 3 are valid.
