Final answer:
The author argues that a few corporations' control of media results in a reduction of differing views and a lack of representation for society's values.
Step-by-step explanation:
In the passage provided, the author suggests that a consequence of media ownership by a few corporations is that it eliminates differences in outlook (b). This concentrated control leads to a media that is not capable of being open and flexible enough to represent the full spectrum of society's values and needs. It also highlights the issue with media consolidation, where a small number of conglomerates exert control over the majority of media outlets, which can lead to a lack of diversity and reduce competition in the marketplace of ideas. Moreover, this oligopoly can mean that the information provided to the public is influenced more by profits and advertiser interests than by the need to inform the public accurately and fairly.
