Which of the following is a correct pair of singular and plural?
Answer & explanation
Correct answer: option 4
The correct answer is Option (4) → Sheep : Sheep
Nouns with the same singular and plural:
A few nouns do not change in the plural, such as sheep, deer and aircraft. One sheep, ten sheep. So “Sheep : Sheep” is a correct pair.
Why the Other Options are Incorrect?
Option 1: Stomach : Stomaches — Incorrect. Here “ch” sounds like “k”, so the noun takes only -s. Stomach → Stomachs.
Option 2: Monarch : Monarches — Incorrect. This “ch” also sounds like “k”. Monarch → Monarchs.
Option 3: Reef : Reef — Incorrect. Reef is one of the nouns ending in -f that take only -s. Reef → Reefs.
