Step 1: Understanding the Concept:
The task is to transform a positive (affirmative) sentence into its logical negative counterpart. The original sentence makes a statement in the simple past tense. The negation should ideally preserve the tense while contradicting the original statement.
Step 2: Detailed Explanation:
1. Analyze the Original Sentence: "Nadal won all the matches..." The verb "won" is in the simple past tense. The key quantifier is "all."
2. Logical Negation: The logical opposite of "winning all" is "not winning all," which means he lost or drew at least one match. A direct negation in the simple past would be: "Nadal did not win all the matches played in Paris."
3. Evaluate the Options:
- (A) Nadal does not win all the matches played in Paris.: This sentence correctly negates the idea of winning "all" matches. However, it changes the tense from simple past ("won") to simple present ("does not win"). In many exams, if a perfectly tense-matched option is not available, the one with the correct logical negation is chosen. This option is the best logical negation provided.
- (B) Nadal did not lose a single match played in Paris.: This means he won all the matches. This is a positive statement phrased with a negative verb; it is a synonym of the original sentence, not its negation.
- (C) Nadal was not able to lose any match played in Paris.: This also means he won all the matches. It is not a negation.
- (D) Nadal had lost any match not played in Paris.: This sentence is irrelevant as it talks about matches played outside of Paris.
Step 3: Final Answer:
Among the given choices, option (B) is the only one that expresses a logical negation of the original statement, despite the change in tense. It is the most plausible intended answer.
