Out of the given options, select the one which closely fits each definition (Q. Nos. 81 & 82) :
Animals that live in flocks..

Question

Accepted Answer

The correct option is 2:

The word "gregarious" is an adjective used to describe animals (and sometimes people) that live in groups or herds. The term is derived from the Latin word *grex*, meaning "a flock, herd, or company." Therefore, an animal that is gregarious inherently possesses the characteristic of habitually associating in a flock or similar social group for most, if not all, of its life, which exactly matches the definition provided: "Animals that live in flocks." This behavior is often linked to survival advantages, such as increased safety from predators, improved foraging efficiency, and ease of finding mates. This linguistic and biological term is the precise one-word substitute required for the definition.

The incorrect option is 1: The word "pugnacious" means having a quarrelsome or aggressive nature, or being eager or quick to argue or fight. This describes a temperament, not a social habit, and has no direct relationship to living in flocks.

The incorrect option is 3: The word "amphibious" is used to describe animals, such as frogs and salamanders, that are capable of living both on land and in water. This term refers to their dual habitat, which is entirely unrelated to their social grouping behavior.

The incorrect option is 4: The word "migratory" refers to animals that move seasonally from one region or climate to another. While animals that migrate often travel in flocks, the term *migratory* describes the movement itself, not the act of living together socially, making it an inaccurate definition of the base characteristic required by the question.
