Final answer:
The most relevant detail supporting why people choose arranged marriages is the belief that parents have the wisdom to pick the perfect partner for their children. These details highlight cultural differences in marriage practices and the values that different societies place on parental involvement. The correct option is B.
Step-by-step explanation:
To support the reasons why people choose to arrange marriages, one would look for evidence that describes the perceived benefits and rationale behind such arrangements.
Therefore, the most relevant detail from the text would be option b: "The basic idea is that the parents know their children better than anyone else, so they will have the wisdom and experience to pick the perfect partner." (Paragraph 6).
This statement underscores the role of parental knowledge and experience in making a seemingly suitable match for their children, suggesting that the practice of arranged marriages is grounded in the belief that parents will choose well for their offspring.
Another supporting detail is option d: "Some American adults take this path, too, trusting their parents to know them and keep their best interests at heart. Do you think you would ever consider marrying a stranger?" (Paragraph 8).
This statement illustrates that even within American culture, where love-based marriages are the norm, some individuals still opt for arranged marriages due to trust in their parents' judgement and decision-making.
Lastly, to provide a broader context for the prevalence of arranged marriages, one could use option c: "Arranged marriages might seem unfamiliar and strange to a Western viewer, but they are actually fairly common around the world" (Paragraph 8).
This points out the global prevalence of the practice, implying that it is a viable and accepted form of marriage in many cultures. The correct option is B.
