Step-by-step explanation:
The correct answer is C. Supporting a government policy change.
All of the other options listed are propaganda techniques commonly used to manipulate public opinion.
A. Presenting only one side of an issue: This technique involves presenting information that supports a specific viewpoint while ignoring or downplaying opposing perspectives.
B. Using glittering generalities: This technique involves the use of vague, positive-sounding words or phrases that lack specific meaning but aim to evoke positive emotions and associations.
D. The bandwagon approach: This technique appeals to the idea that "everyone is doing it" and creates a sense of peer pressure or societal conformity to persuade people to adopt a particular viewpoint or behavior.
On the other hand, supporting a government policy change does not inherently involve the use of propaganda techniques. It can be a legitimate expression of support based on reasoned analysis, evidence, and understanding of the policy's potential benefits and drawbacks.
