With reference to the Hoolock gibbon, consider the following statements: 1. It is India's only ape other than humans. 2. Its populations have declined because of habitat fragmentation. 3. Tree bridges can help it cross linear infrastructure such as railway lines. Which of the statements given above is/are correct?

  1. 1 and 2 only
  2. 2 and 3 only
  3. 1 and 3 only
  4. 1, 2 and 3

Answer

Correct Answer

1, 2 and 3

Explanation

All three statements reflect the report: the Hoolock gibbon is India's only non-human ape, and its populations have declined sharply with habitat fragmentation. Roads and railways isolate forest patches, while planted canopies and braided rope or gantry bridges provide crossings. The article did not identify it as a terrestrial or non-arboreal ape.
