People (who inherit the sickle cell anemia gene from only one parent )seem to be resistant to malaria, an evolutionary advantage that may explain why a genetic condition so debilitating to many individuals has survived in the human population.
后面这个an evolutionary advantage 是指前面整个主句的情况产生情况.

以下是引用bettyofarim在2003-12-7 7:42:00的发言：

可以理解为同位语概括修饰前面整句话吧？

这道题是不是答案错了，应该选c, A 里adavantage 指代不清。

典型的用新名词概括前面文中提到的内容，这里指be resistant to malaria。

我也栽在C上了,但仔细分析后,对C的错误有了明确的理解,分享如下:

People who inherit the sickle cell anemia gene from only one parent seem to be resistant to malaria and have an evolutionary advantage that may explain why a genetic condition so debilitating to many individuals has survived in the human population.

have 不知道该和seem 还是be平行,如果是和seem,意思有问题,如果是和be,就应该是to have以示区别

再说,这里的advantage就是前面描述的过程.

不选c我觉得主要还是从意思上把握的
