📌 The Question:

Which one of the following makes a tool with a stick to scrap insects from a hole in a tree or a log of wood?

(a) Fishing cat
(b) Orangutan
(c) Otter
(d) Sloth bear


Correct Answer: (b) Orangutan


🧑‍🏫 Classroom Explanation

Among the given animals, orangutans are well-documented users of tools in the wild.

  • Orangutans use sticks and twigs to extract insects from holes in trees and logs.
  • They also use leaves as gloves, umbrellas, and sponges, showing advanced problem-solving ability.
  • This behaviour reflects cognitive sophistication and learning capacity among great apes.

Other options:

  • Fishing cat – uses claws and paws, not tools
  • Otter – uses stones mainly to crack shells, not sticks for probing
  • Sloth bear – uses claws and snout, not tools

Hence, option (b) is correct.
