Select the option that can be used as a one-word substitute for the given group of words. A place where birds are kept

Correct — B. An aviary is a large cage, building or enclosure in which birds are kept — the definition the question gives, word for word.

The word is built from Latin avis, bird, plus the place-forming suffix -ary, the same ending that gives apiary for bees and granary for grain.

Nothing else in the list names a bird enclosure, which is why option (b) is the exact substitute.

Why the others are wrong

• (a)
  Zoo — A zoo keeps animals of many kinds for public display. Birds are among them, but the question wants the word whose whole meaning is a place for birds, and zoo is wider than that.
• (c)
  Sanctuary — A sanctuary is a protected area where wildlife lives in its natural habitat, safe from hunting. It is not a structure birds are kept in, and it is not restricted to birds.
• (d)
  Hive — A hive houses bees, not birds. The bee-keeping place word built on the same Latin pattern is apiary, from apis.

One-word substitution rewards word-building far more than memorised lists.

-ary and -arium are place suffixes attached to a Latin root: aviary from avis (bird), apiary from apis (bee), granary from granum (grain), aquarium from aqua (water).

Once the root is visible the options separate themselves. Zoo, sanctuary and hive are all places where creatures live, so the real test is which word means precisely a place for birds.

Key facts

• Aviary: an enclosure or building for keeping birds, from Latin avis, bird.
• Apiary: a place where bee hives are kept, from Latin apis, bee.
• A hive is the structure housing a single colony of bees.
• A wildlife sanctuary protects animals in their natural habitat rather than housing them.

Common traps

• Choosing zoo because birds are kept there too, when the question wants the precise word
• Reading sanctuary as a building rather than a protected stretch of habitat
