D选项的someone不会产生歧义，相反，正是因为有了它才更清晰。原因如下： 1.句子被分号而不是逗号隔开，则说明前后均是一个完整的句子。若如C选项，错误可就大了。一个句子有两个谓语do，这个错误很明显。
2.因为后面是完整的句子，所以someone在这里充当着主语。后面的who comes in for a basketball是对主语someone的限定修饰。
3.从句意来看，这里的someone既非前面所说的Shoppers in sporting goods stores，也不是前面所说的Shoppers in department stores，而限定它的正是刚才第二点所说的那个who的部分，所以会很清晰这个someone其实就是customer。
