原句句子结构：companies could save $58 billion by preventing illness among employees and gain $200 billion through improving performance of workers if they simply provided offices；
原句想要表达的逻辑语义：公司每年能够省下58$ billion，通过在雇员中预防疾病；公司每年能得到200￥billion通过提高员工的表现，如果员工被提供有清新空气的办公室；
ABC:Each year和annually逻辑语义重复，排除；
D:原句的状语关系是：方式状语，用by来表示；这里用in prevention 来表示不符合gmat习惯，动词优于名词；
E:句意没有问题

improved worker performance是名词 improve不做动词

D：in的语义是在什么方面省钱（不平行），应该是通过什么方式省钱（和and后面语义平行）

It's nonsense, because "$xxxx in yyyyy" would mean that yyyy is something that can actually be measured in dollars. E.g., By driving a hybrid car, I will save thousands of dollars in fuel costs. Your business can save over $10,000 per month in shipping costs by using XYZ Courier Service.

each year和annually语义重复排除ABC； DE比较，D选项的in employee illness prevention不能表示“通过某种方式”，and前后都应该是通过某种方式节约钱，排除D； E选项虽然是by doing和through+名词，但是都表示“通过某种方式”，语义平行上比D优，所以选E

By... and through...也算是平行結構，不一定死板地認為是by... and by...

Manhattan: Here are the only words that differentiate (D) and (E): (D) in employee illness prevention .....improving performance of workers... (E) by preventing illness among employees .... improved worker performance... I think this choice boils down to idiom, although parallelism could be useful: (D) reads "companies could save $58B in X...and gain $200B through Y" The phrasing "save $ in X" is not ideal...the only correct usage of this I can think of is "save $ in banks" (i.e. to specify location of saved money). That is not the purpose here. (E) reads "companies could save $58B by preventing X...and gain $200B through Y" where the correct idiom "save $ by doing X" (i.e. to specify how money is saved) is used. Also, X and Y are parallel nouns (illness and performance) correctly completing the idioms "by preventing X (one thing) ...and through Y (some other thing)"

agreement问题，看到they it要时刻想指代什么，D选项最后的they可能指代workers，而实际却指代companies

Serena解析说D的and前后不平行，我觉得是平行的呀 DE的其中一个区别是save in/by，看到一个比较好的解释是save money in sth (从某处省钱) 和 save money by sth （通过某处省钱），供参考

阿星啊阿星
D选项真正的问题在于1、they指代不清，既可以指companies也可以指workers 2、改变了句意，原意是通过避免疾病来节约钱，D选项开头的in employee illness prevention是做句子状语修饰整个句子，没有“通过、凭借”的意思

each year和annually 意思重复复，只保留一个即可。排除ABC D 改变了原句语义。原句是说公司通过便面员工生病从而公司节省了58billion, 而该选项是说公司在防止员工方面节省了58 billion. 另外D中的workers是名词，if后面的they指代不清楚，是指待主语companies还是workers？语义上应该是指companies,但是语法结构上没能清楚地表达。 而E答案中的worker是形容词性，因而if后面的they毫无疑问是指代主语companies.避免了D的问题，且逻辑语义没有问题。

【Each year】 companies in the United States could 【save】 as much as $58 billion annually 通过某种方式by preventing illness among employees and 【gain】 as much as $200 billion 通过某种方式by preventing illness among employees and gain as much as $200 billion through 【improved worker performance】improved worker performance做名词 if 【they】指代前面的companies simply provided offices with cleaner air. 前面已经有了each year，所以后面用annually就重复了！！
