Question

Transform the following into a negative sentence : 
Only a fool could have done it.

Accepted Answer

Option 2, "None but a fool could have done it," is the correct transformation of the sentence "Only a fool could have done it" into a negative sentence. Here's why:

1. **Explanation for Option 2:**
   - The original sentence "Only a fool could have done it" implies exclusivity, meaning that no one except a fool could have accomplished the task. The phrase "None but a fool" captures this exclusivity by stating that no one other than a fool could have done it. The use of "none but" effectively negates the possibility of anyone else doing it, thus transforming the sentence into a negative form while maintaining the original meaning.

2. **Why Other Options are Incorrect:**
   - **Option 1: "Nobody other than a fool will do it."**
     - This option changes the tense from "could have done" (past possibility) to "will do" (future certainty), which alters the meaning of the original sentence. It also implies a future action rather than reflecting on a past event.
   
   - **Option 3: "Not a fool is going to do it."**
     - This option suggests that a fool will not do it, which contradicts the original sentence's implication that only a fool could have done it. It also shifts the focus to a future action rather than addressing the past event.
   
   - **Option 4: "None, not only a fool could do it."**
     - This option is grammatically incorrect and confusing. It suggests that more than just a fool could do it, which directly contradicts the original sentence's meaning that only a fool could have done it.

In conclusion, Option 2 accurately transforms the original sentence into a negative form while preserving its intended meaning, making it the correct choice.
