问题 PASSAGE THREE [br] What proves two black holes can coexist in one galaxy?

选项

答案 Chandra．

解析根据题目中的can coexist in one galaxy定位到首段。该段说钱德拉望远镜首次证实两个神秘的事物可共存于同一星系中。全文通篇都在说黑洞，下文不断出现two black holes，据此可推断该段中的two mys—teries指的就是two black holes，而题目中的proves对应原文的provides first evidence，由此可见答案是Chandra。注意题目问的是What，而不是Who，所以不能认为答案是“科学家”。
