Correct Usage of "Pair of Scissors" as Singular
Step 1: Understanding the Rule
The word "scissors" is always plural, but when referring to "a pair of scissors," it is treated as singular.
Step 2: Choosing the Correct Verb Form
The correct phrase is:
"A pair of scissors is blunt."
Step 3: Eliminating Incorrect Options
- "Are blunt" (Option A): Incorrect because "pair" is singular, requiring "is" instead of "are".
- "Has blunt" (Option B): Incorrect because "has" should be followed by a past participle, not an adjective.
- "Scissor" (Option C): Incorrect because "scissors" is always plural, and "scissor" as a singular noun is incorrect.
Step 4: Correct Usage
The correct sentence should be:
"A pair of scissors is blunt."
Final Answer:
Thus, the correct answer is Option D ("A pair of scissors is blunt").
