The correct answer is: A. PRSQ
The first sentence, S1, states the essence of democracy. The second sentence, P, supports this by stating that when the people are active participants, democracy flourishes. The third sentence, Q, further supports this by stating that democracy is founded on a faith in the people’s overall judgement. The fourth sentence, R, provides an example of what happens when the people do not participate, and the fifth sentence, S, provides an example of what happens when the people are informed. The sixth sentence, S6, summarizes the main points of the paragraph.
The other options are incorrect because they do not follow the logical flow of the paragraph. Option B, PSRQ, starts with the example of what happens when the people are informed, but this example does not support the main point of the paragraph, which is about the essence of democracy. Option C, RPSQ, starts with the example of what happens when the people do not participate, but this example does not support the main point of the paragraph, which is about the essence of democracy. Option D, SPQR, starts with the summary of the paragraph, but this summary does not provide any support for the main point of the paragraph.
