The stimulus text supports the scientist’s main conclusion by highlighting the similarities between recent scientific research and Newton’s Principia. It does not discuss objections to the conclusion, nor does the scientist call the stimulus text into doubt.

The stimulus text is a premise that supports the main conclusion by noting a similarity between Newton’s Principia and recent scientific research—not a difference. Additionally, it notes how people reacted similarly to both, not how similar the recent findings were to Newton’s.

The stimulus text directly supports the scientist’s main conclusion by highlighting the similarities between recent scientific research and Newton’s Principia. It doesn’t support the claim that the “barriers to communication between scientists and the public are not impermeable.”

The stimulus text explains why Newton’s Principia is relevant to the main conclusion. Just as few people initially understood Principia, few understand today’s scientific research, making Principia a good example of what could happen with recent research.

The stimulus text serves to highlight the similarities between recent scientific research and Newton’s Principia—not to call their similarity into question. The text explains that the two are similar because only a few people initially understood each.
