124. Outsourcing is the practice of obtaining from an independent supplier a product or service that a company has previously provided for itself. Since a company’s chief objective is to realize the highest possible year-end profits, any product or service that can be obtained from an independent supplier for less than it would cost the company to provide the product or service on its own should be outsourced. Which of the following, if true, most seriously weaken the argument? B. successful outsourcing requires a company to provide its supplier with information about its products and plans that can fall into the hands of its competitors and give them a business advantage. C.Certain tasks, such as processing a company’s payroll are commonly outsourced, whereas others, such as handling the company’s core business, are not. 我觉得any product or service that can be obtained from an independent supplier for less than it would cost the company to provide the product or service on its own should be outsourced才是结论，应该是对这个结论削弱。但正确答案是B，那就是对Since a company’s chief objective is to realize the highest possible year-end profits削弱，可如果从语法角度看，SINCE从句表原因，主句才是结果，应该对结果削弱才对。到底哪句才是结论呢，为什么C不对？？ |
