Question

Choose the correct negative transformation of the sentence: 
'How can I ever repay your debt?'

Accepted Answer

Option 2, "I can never repay your debt," is the correct negative transformation of the sentence "How can I ever repay your debt?" because it effectively conveys the intended meaning of impossibility or inability to repay the debt. Here's a detailed explanation:

1. **Explanation for Option 2:**
   - The original sentence, "How can I ever repay your debt?" implies a sense of doubt or uncertainty about the ability to repay the debt. The transformation to a negative sentence should maintain this sense of impossibility.
   - Option 2 uses "never," which is a negative adverb, to express the idea that repaying the debt is not possible at any time. This aligns with the original sentence's implication of doubt or impossibility.
   - The structure "I can never repay your debt" is grammatically correct and clearly communicates the intended meaning.

2. **Explanation for why other options are incorrect:**

- **Option 1: "I cannot ever repay your debt."**
     - While this option uses "cannot," which is a negative form of "can," the combination with "ever" is less common and can sound awkward. It doesn't convey the same sense of impossibility as "never" does.
     - The phrase "cannot ever" is not as strong or definitive as "can never," making Option 2 a better choice for expressing the intended meaning.

- **Option 3: "How can I not ever repay your debt?"**
     - This option is a question, similar to the original sentence, but it introduces a double negative with "not ever," which can be confusing and is not a standard way to express impossibility.
     - The structure of this sentence does not effectively transform the original sentence into a clear negative statement.

- **Option 4: "I cannot never repay your debt."**
     - This option contains a double negative ("cannot never"), which is grammatically incorrect in standard English. Double negatives can lead to confusion and often imply the opposite of the intended meaning.
     - The use of both "cannot" and "never" together cancels out the negative meaning, making this option incorrect.

In conclusion, Option 2 is the correct choice because it clearly and effectively transforms the original sentence into a negative statement that conveys the intended meaning of impossibility.
