Passage Summary: Exercise helps lower cholesterol, which prevents arteries from hardening, which in turn prevents them from getting blocked; therefore, exercise prevents blockages.

Conclusion: Engaging in moderate exercise reduces the likelihood of experiencing arterial blockages caused by blood clots.

Reasoning: Exercise reduces cholesterol, and reduced cholesterol leads to a chain reaction that eventually prevents blockages.

Analysis: This argument is structured as a conditional chain: Exercise leads to Lower Cholesterol, which leads to Lower Hardening, which leads to Lower Blockage. However, the stimulus includes a significant caveat: 'if the data reported in a recent study are correct.' To make the conclusion follow with absolute logical certainty, we must assume that the data from that study are indeed accurate. Look for an answer that confirms the truth of the premise regarding exercise and cholesterol to bridge the final gap in the logical chain.
