问题 What are some of the problems that Chromium Ⅵ can cause?
What happened to people who lived in Willits from 1964～19957
选项 A、They all got sick.
B、They are at higher risk of cancer and asthma.
C、They lost their jobs at the plant.
D、Most of them moved away.
答案B
解析 见原文倒数第三段。1995年的30年前应是1964年。从那时到1995年，因为没有安全限制，所以铬仍然在释放。因此人们处于患癌症和气喘病的高度危险中。
