个人愚见，从两个方面解释下：
1、through的用法。through作介词表达“通过、凭借”的意思时，少见+doing的形式，一般为through the method/relationship/person等具体的名词短语，私以为“通过做……”有更好的表达像by+v-ing，这应该还是语言习惯；
2、核心词的问题。through improved worker performance和through improving performance of workers的核心词有明显的不同，前者强调的是“worker performance员工绩效”，后者则强调improving这个动作，这里更合理的理解应该是“公司如果仅仅为办公室提供更清洁的空气，就可以通过提高 的 员工绩效获得2000亿” ，而不是“就可以通过提高员工绩效获得2000亿” ，可以察觉到两者细微的差别。 前者ed形式表被动，作定语修饰绩效的性质，表达了“提高”是前面条件状语的结果的意思；后者ing形式表主动，表达了“提高员工绩效”还要施加其他的动作，提供清洁空气还不够。

核心词的解释挺有道理的
Option B- is close but it is not addressing the issue. We need to address how this bid will generate profits. Here it talks about the other products etc.
D：This choice implies that in addition to providing tires to Maxilux at the price in their bid, Rubco can expect to sell replacement tires to people who purchase the Max 100. These replacement tires are not part of the bid, so they can be sold at a different price. That's why Rubco could make a profit by winning the bid, even if analysts are correct that the company will only just cover their costs in supplying the tires to Maxilux. (D) is correct.
