问题 Nuclear power plants are some of the largest producers of______wastes, with each plant producing barrels of radioactive material that must be stored in special protective containers.
选项 A、biodegradable
B、hazardous
C、reasonable
D、durable
答案B
解析 hazardous的意思为“危险的，危害的”，如：These conditions are veryhazardous for shipping．(这些情况对航海非常不利。)句意：核电站是某些有害废物的最大制造者。每一个核电站产生成桶的放射性物质，必须存放在专门的防护容器里。故选B。其他三项分别意为：biodegradable能进行生物降解的；reasonable合理的，适度的；durable持久的，耐用的。
