Consider the following statements based on a close reading of the above passage.

1. Machine learning algorithms have made the prediction of ecological responses to climate change significantly more accurate.
2. Genomic technologies provide information about individual species, not about their interactions or histories.
3. Satellite imagery, drones, and sensors can now facilitate passive management of natural resources.
4. The intricately connected life on Earth stands endangered because of advancements in Genomic technologies.

Which of the above statement/s is/are incorrect?

  • A.1 only
  • B.2, 3 and 4
  • C.1 and 4
  • D.1, 2 and 3

Answer: B

Statements 2, 3 and 4 are incorrect.

Statement 2 is false: the passage says genomic technologies reveal the web of species interactions and evolutionary histories. Statement 3 is false: the passage speaks of proactive management, aided by real-time monitoring, not passive management. Statement 4 is false: the passage says the technologies help safeguard life on Earth, not endanger it.

Statement 1 is taken as acceptable by the key: the passage says machine learning algorithms predict ecological responses to climate change and aid proactive management, and the key reads this as improved prediction. It is the loosest of the four, but it is not contradicted by the passage. So options with 1 among the incorrect ones (A, C, D) are wrong.
