Correct Answer:
C. Flock
This question tests your knowledge of collective nouns, which are words used to describe a group of specific items or animals. The analogy provided is 'Fish' is to 'Shoal'. A 'shoal' is the correct collective noun for a group of fish. Following this pattern, we need to find the correct collective noun for 'Bird'.
- A: Pack is typically used for wolves or dogs.
- B: Herd is used for large mammals like cattle, elephants, or deer.
- C: Flock is the correct collective noun for a group of birds.
- D: Swarm is used for insects, particularly flying ones like bees or flies.
Therefore, just as a group of fish is called a shoal, a group of birds is called a flock, making 'Flock' the correct choice to complete the word pair.
