The main purpose of the passage is to discuss changes in the perception of the news media as a source of public knowledge. The correct option is B.
Given a passage that is shown in the attached images.
Option B is the best answer. The passage states that historically, "newspapers like The Times and broadcasters like the BBC have been seen by many as reliable substitutes for authoritative agendas and conventional wisdom" ( lines 27-30). But he went on to say that “there is a growing feeling. . . that the news media should be "informative rather than arbitrary" (lines 70-73). Together, these lines indicate the main purpose of the passage, which is to discuss how people perceive people. News media people are changing from an authoritative voice to a mere informational voice.
Option A is incorrect because the passage deals with changes in the way news is perceived but does not primarily focus on the technological changes that may have resulted in those or other changes. Option C is incorrect because even if the passage implies that viewers might increasingly believe a journalist’s values can affect the news stories being produced, it does not provide specific examples of that happening. Option D is incorrect because the passage begins with the simple sentence “The news is a form of public knowledge” (line 1) and makes no attempt to refute that claim.
Hence, the main purpose of the given passage is to discuss changes in the perception of the news media as a source of public knowledge.
