   The figures include a number of costs【C2】______with air pollution. Lost income alone amounts to $225 billion a year.
   The report includes both indoor and outdoor air pollution. Indoor pollution, which includes【C3】______like home heating and cooking, has remained【C4】______over the past several decades despite advances in the area.

选项
答案E
解析 从句子结构来看，空格位于非限制性定语从句中。当非限制性定语从句中的关系代词作介词宾语时，介词要前置。介词前置之前，非限制性定语从句的语序为“which individuals have little______over”。因此空格处应填入名词，与have和over搭配构成动词短语，作从句的谓语。结合句意，“过早死亡的危险因素之一是我们呼吸的空气，对此个人几乎是无法______的”。由此可知，备选项中只有control(控制，管理)符合句意，have control over表示“能控制……”。故答案为E。
