Argument EvaluationDiff: Easy
Logic Breakdown
Passage Summary: A study showed that people taking garlic pills had much better heart-health numbers than people taking sugar pills, so garlic must be good for your heart.
Conclusion: Consuming garlic is an effective way to lower blood fats and decrease the risk of heart disease.
Reasoning: In a four-month study, patients taking garlic saw significantly higher drops in cholesterol and triglycerides compared to a control group taking a fake pill.
Analysis: To evaluate this study, we need to know if the two groups were truly comparable. If the garlic group happened to be on a better diet or exercise regimen by coincidence, the garlic might not be the cause of the improvement. A good tutor would tell you to look for an answer that probes for 'confounding variables' or differences between the groups that weren't controlled for. We need to ensure that the only significant difference between the two groups was the garlic itself.
