Study the following information carefully and answer the given questions:

In a family of eight members, Harry is married to Grace. Alan is the only son of Grace, and Becky is Alan's sister. Emma is the wife of Alan. Fred is Emma's son. Chris is the husband of Becky, and David is Chris's son.

Which of the following represents a married couple?

Correct Answer: Alan, Emma

To determine which pair represents a married couple, let's step-by-step trace and break down the family relations given in the question:

1. Harry and Grace: "Harry is married to Grace."
⇒ Harry (Husband) = Grace (Wife)

2. Alan, Grace, and Becky: "Alan is the only son of Grace, and Becky is Alan's sister."
⇒ Alan and Becky are siblings (children of Harry and Grace).

3. Emma and Alan: "Emma is the wife of Alan."
⇒ Alan (Husband) = Emma (Wife)
Therefore, Alan and Emma form a married couple.

4. Fred: "Fred is Emma's son."
⇒ Fred is the son of Alan and Emma.

5. Chris, Becky, and David: "Chris is the husband of Becky, and David is Chris's son."
⇒ Chris (Husband) = Becky (Wife), and David is their son.

Now, let's check the options against our deductions:

• Chris, Emma: Incorrect (Chris is married to Becky, Emma is married to Alan).
• Alan, Becky: Incorrect (They are brother and sister).
• David, Grace: Incorrect (David is Grace's grandson).
• Harry, Becky: Incorrect (Harry is Becky's father).
• Alan, Emma: Correct (Alan is married to Emma).

Hence, the correct pair representing a married couple is Alan, Emma.
