The well-being of a society is enhanced when many of its people question authority?
对于政治方面的权威：The more the people are questioning the authority, the more the society’s people care about what the authority is doing. Questioning authority forces governments to be more democratic, efficient, responsible and honest.
对于其他社会层面的权威：Questioning authorities promotes innovation, invention, and discovery.
从必须性来说： The opinions, claims and theories of authorities may become out of date, or have inherent drawbacks. Questioning existing authority is necessary for social progress.
从后果来说：Mass resistance to authority can escalate to violent protest and rioting, and impede development and progress.
对于社会层面的权威：Some positive challenges do not necessarily come from a large number of people; a few key individuals can pose profound impact.
It is necessary to make clear differentiation between positive and vicious challenge.
The following appeared in a memo to the board of directors of Bargain Brand Cereals.
"One year ago we introduced our first product, Bargain Brand breakfast cereal. Our very low prices quickly drew many customers away from the top-selling cereal companies. Although the companies producing the top brands have since tried to compete with us by lowering their prices and although several plan to introduce their own budget brands, not once have we needed to raise our prices to continue making a profit. Given our success in selling cereal, we recommend that Bargain Brand now expand its business and begin marketing other low-priced food products as quickly as possible."

Because of the proximity and likeness of Mars to Earth, scientists have long speculated about the possibility of life on Mars. Roughly three centuries ago, astronomers observed Martian polar ice caps, and later scientist’s discovered other similarities to Earth, including length of day and axial tilt. But in 1965, photos taken by the Mariner 4 probe revealed a Mars without rivers, oceans or signs of life. Moreover, in the 1990s, it was discovered that unlike Earth, Mars no longer possessed a substantial global magnetic field, allowing celestial radiation to reach the planet's surface and solar wind to eliminate much of Mars's atmosphere over the course of several billion years. More recent probes have investigated whether there was once liquid water on Mars. Some scientists believe that the presence of certain geological landforms definitively resolves this question. Others posit that wind erosion or carbon dioxide oceans may be responsible for these formations. Mars rovers Opportunity and Spirit, which landed on Mars in 2004, have both discovered geological evidence of past water activity. These findings substantially bolster claims that there was once life on Mars.
The passage is primarily concerned with which of the following?
(A) Disproving a widely accepted theory.
(B) Initiating a debate about the possibility of life on Mars.
(C) Presenting evidence in support of a controversial claim.
(D) Describing the various discoveries made concerning the possibility of life on Mars.
(E) Detailing the findings of the Mars rovers Opportunity and Spirit.
通读段落，可知围绕主题是the possibility of life on Mars，且涉及了不止一个，而是很多个不同的discoveries。
