In Swartkans territory， archaeologists discovered charred bone fragments dating back 1 million years. Analysis of the fragments， which came from a variety of animals， showed that they had been heated to temperatures no higher than those produced in experimental campfires made from branches of white stink-wood， the most common tree around Swartkans.　　Which of the following， if true， would， together with the information above， provide the best basis for the claim that the charred bone fragments are evidence of the use of fire by early hominids？
　　（A） The white stinkwood tree is used for building material by the present day inhabitants of Swartkans.
　　（B） Forest fires can heat wood to a range of temperatures that occur in campfires.
　　（C） The bone fragments were fitted together by the archaeologists to form the complete skeletons of several animals.
　　（D） Apart from the Swartkans discovery， there is reliable evidence that early hominids used fire as many as 500 thousand years ago.
　　（E） The bone fragments were found in several distinct layers of limestone that contained primitive cutting tools known to have been used by early hominids.

123. 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 weakens
the argument?


(A) If a company decides to use independent
suppliers for a product, it can generally
exploit the vigorous competition arising among
several firms that are interested in supplying
that product.
(B) Successful outsourcing requires a company to
provide its suppliers 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.
(D) For a company to provide a product or service
for itself as efficiently as an independent supplier
can provide it, the managers involved need to be
as expert in the area of that product or service
as the people in charge of that product or
service at an independent supplier are.
(E) When a company decides to use an independent
supplier for a product or service, the independent
supplier sometimes hires members of the
company’s staff who formerly made the product
or provided the service that the independent
supplier now supplies.



Successful outsourcing requires a company to
provide its suppliers with information about its
products and plans that can fall into the hands of
its competitors and give them a business
advantage.

b的意思是说成功的Outsourcing需要这个公司将自己的（技术或者其他的）信息以及计划透露给它的Outsourcing供应商，这样就有可能讲这些信息落入这个公司的竞争者的手里，并使这些竞争者获得有利条件

所以毫无疑问选这个答案

不对吧？人家that的意思是指products and plants，你这个that指的前面那句话，应该是成功的Outsourcing需要这个公司将自己的（技术或者其他的）信息以及计划（这些可能落入这个公司的竞争者的手里，并使这些竞争者获得有利条件的信息和计划）
透露给它的Outsourcing供应商， 既然很危险，为什么还说是成功的？这我十分不理解
