?Q29.
?Columnist

eople should avoid using a certain artificial fat that has been touted as a resource for those whose medical advisers have advised them to reduce their fat intake.Although the artificial fat, which can be used in place of fat in food preparation, has none of the negative health effects of fat, it does have a serious drawback:it absorbs certain essential vitamins, thereby preventing them from being used by the body.
?In evaluating the columnist's position, it would be most useful to determine which of the following?
?(A) Whether increasing one's intake of the vitamins can compensate for the effects of the artificial fat
?(B) Whether the vitamins that the artificial fat absorbs are present in foods that contain the fat
?(C) Whether having an extremely low fat intake for an extended period can endanger the health
?(D) Whether there are any foods that cannot be prepared using the artificial fat as a substitute for other fats
?(E) Whether people are generally able to detect differences in taste between foods prepared using the artificial fat and foods that are similar except for the use of other fats

Q17.
Outsourcing is the practice of obtaining from an independent supplier a product or service that a company has previously provided for itself. Vernon, Inc., a small manufacturing company that has in recent years experienced a decline in its profits, plans to boost its profits by outsourcing those parts of its business that independent suppliers can provide at lower cost than Vernon can itself.
Which of the following, if true, most strongly supports the prediction that Vernon's plan will achieve its goal?
(A) Among the parts of its business that Vernon does not plan to outsource are some that require standards of accuracy too high for most independent suppliers to provide at lower cost than Vernon can.
(B) Vernon itself acts as an independent supplier of specialized hardware items to certain manufacturers that formerly made those items themselves.
(C) Relatively few manufacturers that start as independent suppliers have been able to expand their business and become direct competitors of the companies they once supplied.
(D) Vernon plans to select the independent suppliers it will use on the basis of submitted bids.
(E) Attending to certain tasks that Vernon performs relatively inefficiently has taken up much of the time and effort of top managers whose time would have been better spent attending to Vernon's core business.

答案E.可我觉得C也说得通呀: Vernon的目的是boost profits，那么suppier变成竞争对手，profits可能反而受到影响。请NN帮忙指正~
