That Fulani man has a large … of sheep.

Analyze the question: This tests collective nouns, the special words used for groups of animals or things. The group here is sheep.

Explain the concept: Different animals have different group names:

• A flock of sheep, birds, or goats
• A herd of cattle, elephants, or deer
• A pack of wolves or dogs
• A swarm of bees
• A school/shoal of fish

Step-by-step solution:

• A. multitude means a very large crowd, usually of people. It is not the specific collective noun for sheep.
• B. herd is used for cattle, cows, elephants, and similar animals. It is commonly used for the Fulani man's cattle, but the gap asks about sheep. (Note that "herd" is often used loosely for sheep too, but "flock" is the standard term.)
• C. swine means pigs. It is not a collective noun for sheep, and it doesn't fit the sentence.
• D. flock is the standard collective noun for sheep.

So the sentence reads: "That Fulani man has a large flock of sheep."

Tip: Link the animal to its group word. Sheep go with flock (think of a shepherd tending his flock), and cattle go with herd. Test-setters often put "herd" as a distractor when the animal is sheep, especially in a Fulani context where people think of cattle.
