答案与题解：
1． C 短文的第一和第二段提供了答案。第一段第一句说，特大质量的黑洞能够撕裂靠近它们的恒星；第二段的第二句说，由于它们之间力量的悬殊，恒星内部会发生核爆炸。第五段提及黑洞吞噬恒星的问题。C的内容文章中没有找到，所以应该选择C.
2． A 该段告诉我们，两种研究的焦点在于是否会引起核爆炸。所以，A是正确选择。
3． D 第四段告诉我们，模拟实验发现，整个的条件会引起核爆炸，这将彻底毁灭恒星，但恒星的一些物质会被强力的爆炸抛出黑洞。所以，A、B、C三个选择的内容都是正确的说法，而D不是。
4． C 第五段中its matter starts swirling into the hole itself，这里的its matter指的是the star’smatter，即被爆炸抛出黑洞的恒星物质。所以应选C.
5． B 根据全篇语境，disruption在这里的意思是第一段提到的tearing apart.
