D：The phrasing "save $ in X" is not ideal...
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)" "preventing" is a noun form ("gerund"), as can be seen from the fact that it's the object of a preposition (by). in fact, -ING forms by themselves are never verbs
反思：1.动词ing形式本身不做动词！！
2.main clause 的两个主要动作：…save…and…gain…… ，进一步…save$ by X (preventing illness)…and…gain $ through Y(improved performance).
