    Question

    Read the following passage and answer the question

    that follows: In a recent ecological study conducted in the Himalayan region, scientists found that the average temperature of high-altitude areas has increased by nearly 1.5°C over the last four decades. This warming trend has caused glacial retreat, erratic weather patterns, and changes in flora and fauna distribution. Many species that were once found only at lower altitudes are now migrating upward, disrupting the existing ecological balance. The study warns that if the current trend continues, several endemic species may face extinction due to habitat loss. Which of the following can be inferred from the passage?
    A Climate change is affecting biodiversity in the Himalayan region. Correct Answer Incorrect Answer
    B All glacial regions across the world are experiencing the same warming trend. Correct Answer Incorrect Answer
    C The Himalayan region had stable temperatures before the last four decades. Correct Answer Incorrect Answer
    D Rising temperatures may lead to extinction of some Himalayan species. Correct Answer Incorrect Answer
    E Both option A and D Correct Answer Incorrect Answer

    Solution

    Let’s evaluate each statement: Statement A: Climate change is affecting biodiversity in the Himalayan region.
    Can be inferred. The passage directly mentions the impact on flora, fauna, and species movement due to rising temperatures. Statement B: All glacial regions across the world are experiencing the same warming trend. Cannot be inferred. The passage is specific to the Himalayan region. It makes no claim about global patterns. Statement C: The Himalayan region had stable temperatures before the last four decades. Cannot be inferred. The passage states a rise in temperature over the last 40 years, but does not state anything about conditions before that. Statement D: Species migrating upward will adapt to the new environment easily. Cannot be inferred. The passage mentions disruption in ecological balance and extinction risks, not easy adaptation. Statement E: Rising temperatures may lead to extinction of some Himalayan species. Can be inferred. The last line clearly says endemic species may face extinction due to habitat loss.
