How did interracial marriage get approved

问题单项选择题

How did interracial marriage get approved in Alabama

A．By a Supreme Court ruling.

B．By state legislation.

C．By a vote of the residents.

D．By the social trend that interracial marriages keep increasing.

答案

参考答案：C

解析：特定信息的找寻和判断。通过对Alabama婚姻情况这一特定信息进行找寻，发现原文第二段最后一句提到Alabama是最后一个放弃混合婚姻禁令的州时说明这是“just a 60%-to-40% vote by residents”，即“当地居民60%对40%投票的结果”，这与选项c内容吻合。因此，该选项的说法是正确的。注意：根据数字信息迅速做出推断是解答本题的关键。
