Question

Which one of the following words does not have the same form in singular and plural?

• A. Sheep
• B. Crisis
• C. Fish
• D. Aircraft

Answer 1

Answer:

B. Crisis

• The plural of 'crisis' is 'crises'.
• Plural of 'sheep' is 'sheep'.
• 'Fish' is the most common plural form of the word 'fish'.
• "Aircraft" is a collective word, like "sheep" and "deer", and so it remains same in both singular and plural.
