大全里的一题，，为什么答案不统一。。。

From time to time, the press indulges in outbursts of indignation over the use of false or misleading information by the U.S. government in support of its policies and programs. No one endorses needless deception. But consider this historical analogy. It is known that Christopher Columbus, on his first voyage to the New World, deliberately falsified the log to show a shorter sailing distance for each day out than the ships had actually traveled. In this way, Columbus was able to convince his skeptical sailors that they had not sailed past the point at which they expected to find the shores of India. Without this deception, Columbus’s sailors might well have mutinied, and the New World might never have been discovered.
*10. The author of the passage above assumes each of the following EXCEPT:
(A) Government deception of the press is often motivated by worthy objectives.
(B) Without government deception, popular support for worthwhile government policies and programs might well fade.
(C) Attacks on the government by the press are often politically motivated.
(D) Deception for deception’s sake should not be condoned.
(E) A greater good may sometimes require acceptance of a lesser evil.
