उत्तर और व्याख्या · explanation in English
Answer: (b) 1 और 2
The western hoolock gibbon, India's only ape, is assessed as Endangered by the IUCN, and Assam's Hollongapar Gibbon Wildlife Sanctuary in Jorhat is named after it. Gibbons are expert brachiators that swing arm over arm through the canopy, but they are small, light apes, not heavily built like gorillas.
- ✓ 1. Hollongapar Gibbon Wildlife Sanctuary (about 21 sq km, Jorhat district, Assam) is named after the hoolock gibbon; the western hoolock (Hoolock hoolock) is listed as Endangered on the IUCN Red List.
- ✓ 2. Gibbons have very long forearms and move mainly by brachiation, swinging from branch to branch and covering more than 3 m in a single swing.
- ✗ 3. Gibbons are the lightest apes, weighing roughly 4–13 kg; the agility comes from a slender, light build, not a heavy gorilla-like body.
Remember · Western hoolock gibbon: India's only ape, IUCN Endangered, Schedule I; Hollongapar Gibbon Sanctuary, Jorhat (Assam); moves by brachiation.
