问题     A study in 26 countries shows that women using the pill for birth control are 5 times more likely to die of heart disease or hypertension than nonusers. But a Harvard Medical School study says that pregnancy is 5 times as likely to kill a woman as is the pill.
选项
答案 根据26个国家的情况所作的一份调查报告表明：使用口服避孕药的妇女，因心脏病或高血压致死的可能性5倍于不使用这种避孕药的妇女。而哈佛大学医学院的一份研究报告则说，妇女因怀孕致死的可能性5倍于口服避孕药致死的妇女。
