Correct Option: B. Did I buy my wife a red shoe? Explanation of the Correct Answer: The sentence "I bought my WIFE a red dress" places emphatic stress on the word "WIFE." This means that the speaker is emphasizing the fact that it was their wife who received the dress, possibly to clarify or correct a misunderstanding. When we analyze the options, we need to look for a question that challenges or contrasts the emphasis on "WIFE" or the specific item "red dress."

1. Option A: Did I buy my husband a red dress?
2. This option is incorrect because it changes the subject from "wife" to "husband." The emphasis on "WIFE" indicates that the speaker is specifically talking about their wife, not a husband. Therefore, this option does not relate to the original sentence.
3. Option B: Did I buy my wife a red shoe?
4. This option is correct because it maintains the subject "wife" but changes the object from "red dress" to "red shoe." This question implies a contrast to the original statement, suggesting that the listener might have misunderstood or misremembered the item. The emphasis on "WIFE" remains intact, making this option the most relevant.
5. Option C: Did he buy my wife a red dress?
6. This option is incorrect because it changes the subject from "I" to "he." The original sentence emphasizes that the speaker (I) bought the dress for their wife, so this option does not relate to the original statement.
7. Option D: Did I buy my wife a black dress?
8. This option is incorrect because it changes the color of the dress from "red" to "black." While it still refers to the "wife," it does not maintain the same item (red dress) and instead introduces a different color, which does not align with the emphasis on "WIFE" in the original sentence.

Summary of Key Points:

• The emphasis on "WIFE" indicates that the speaker is clarifying who received the dress.
• The correct option (B) maintains the subject "wife" while changing the object to a different item (red shoe), which aligns with the emphasis.
• Options A, C, and D either change the subject or alter the item in a way that does not relate to the original statement.
• Understanding emphatic stress helps in identifying the correct context and meaning in sentences.

Revision Summary:

• Emphatic stress highlights specific words for clarity or correction.
• The correct option should maintain the subject while potentially altering the object.
• Changing the subject or the key details (like color) leads to incorrect options.
• Always analyze the emphasis to determine the most relevant question or statement.
