Passage Summary: Steven wants to cut the legal blood alcohol limit in half to discourage social drinkers and make roads safer. Miguel disagrees, arguing that the change won't help much because the real danger comes from heavy drinkers who are already driving far above the current legal limit.

Conclusion: Steven believes lowering the blood alcohol limit will significantly increase highway safety, while Miguel believes it will have little effect.

Reasoning: Steven argues that a lower limit will deter social drinkers and improve safety; Miguel contends that safety will not improve because the primary threat is heavy drinkers who already ignore current limits.

Analysis: To identify the point at issue, we apply the 'Agree/Disagree' test to the speakers' claims. Steven explicitly states that the lower limit will result in 'significantly increased highway safety,' whereas Miguel directly counters this by saying it would have 'little effect.' While they may both acknowledge that heavy drinkers are a problem, they fundamentally disagree on the efficacy of this specific policy change. Look for an answer choice that focuses on whether lowering the legal blood alcohol limit will actually lead to a significant improvement in road safety.
