Question

Fill in the blank with the correct conjunction : 
It is _____ useful _____ ornamental.

Accepted Answer

The correct conjunction to fill in the blank is "neither, nor," which is Option 3. Let's explore why this is the correct choice and why the other options are incorrect.

1. **Explanation for Option 3 ("Neither, nor"):**
   - The phrase "neither, nor" is used to connect two negative alternatives. In the sentence "It is neither useful nor ornamental," it indicates that the subject is not useful and also not ornamental. This conjunction pair effectively communicates the absence of both qualities, making it the most appropriate choice for the sentence.

2. **Why the other options are incorrect:**

- **Option 1 ("Whether, or"):**
     - The conjunction "whether, or" is typically used to present two possibilities or alternatives, often in a context where a decision or choice is involved (e.g., "I don't know whether to go or stay"). It does not fit the context of the sentence, which is stating the absence of both qualities rather than presenting alternatives.

- **Option 2 ("Both, or"):**
     - The conjunction "both, or" is not a standard conjunction pair in English. Typically, "both" is paired with "and" to indicate the presence of two qualities or items (e.g., "both useful and ornamental"). Therefore, this option is grammatically incorrect and does not convey the intended meaning of the sentence.

- **Option 4 ("Either, but also"):**
     - The phrase "either, but also" is not a standard conjunction pair. "Either" is usually paired with "or" to present two alternatives (e.g., "either useful or ornamental"). The addition of "but also" does not logically fit the structure of the sentence, which aims to negate both qualities rather than present them as alternatives or additions.

In conclusion, Option 3 ("Neither, nor") is the correct choice because it accurately conveys the absence of both qualities—usefulness and ornamentation—in the sentence. The other options fail to provide the correct grammatical structure or meaning required by the sentence.
