问题如下：
Bill is a philanthropist who is approached by four charitable organisations that each claim to have a solution that reduces mortality by 15% in their specific area of focus if they receive $300 million. Bill's aim is to reduce mortality rates as much as possible. Which one of the following charities should he choose?选项：
A.A charity focusing on drought. B.A charity focusing on malaria. C.A charity focusing on pollution. D.A charity focusing on violence.解释：
根据题干信息，Bill的目标是尽可能地降低死亡率，而污染是当今世界上导致疾病和过早死亡的最大环境原因。因此Bill会选择投资在关注“污染”的慈善组织。教材信息：“燃烧化石燃料——尤其是煤炭、汽油和柴油——是空气中细颗粒物(PM2.5)的主要来源，也是造成全球死亡和疾病负担的关键因素....据估计，与化石燃料相关的PM2.5含量较高的地区死亡率最高。
A选项关注的是干旱，B选项关注的是疟疾，D选项关注的是暴力。
有点奇怪，题干说each claim to have a solution that reduces mortality by 15% in their specific area，那大家降低的死亡率都是一样的呀，为啥还有区别？仿佛是在问一斤铁和一斤棉花哪个重...
