In a transportation company, a certain syndrome often attributed to stress by medical experts afflicts a significantly higher percentage of workers in Department F than in any other department.
Conclusion (conclude, therefore)
The work done in Department F subjects workers to higher stress levels than does the work in the other departments in the company.j
Evidence
Department F has a higher percentage of workers with syndrome X than does any other department, and syndrome X is often attributed to stress.
Evaluate
This argument follows a common pattern: - it presents a Curious Fact (almost always an asymmetric comparison) in the evidence - the conclusion assumes or states a causal explanation for that curious fact.
Curious Fact ... why do workers in Dept F have a higher rate of getting this syndrome that's associated with stress?
Author's Explanation ... it must be that workers in Dept F undergo more stress than do workers in other departments.
We always approach Explain Curious Fact arguments looking at the same two pressure points: - Alternate Explanations for the curious fact - the plausibility of the Author's Explanation
What could be an alternate reason for why people in Dept F have higher rates of this syndrome? - maybe the syndrome isn't really caused by stress; it's caused by something else like lack of sleep, and people in Dept F get less sleep.
- maybe it is caused by stress, but the stress isn't coming from Dept F; it's just that the workers who work in Dept F have more stressful lives for other reasons (maybe Dept F is full of parents of young children, whereas the other departments more often have people without children or with low-maintenance children).
Goal
Since this is Strengthen, we would want an answer to rule out an Alternate Explanation. Or, more commonly on Strengthen, we would want it to increase the plausibility of the Author's Explanation.
The most common way to increase plausibility of a Cause / Effect connection on LSAT is to hear about data points that show No Cause / No Effect (i.e. when the cause was absent, the effect was absent).
So if we heard something like , that would heavily suggest that Department F was the causal difference-maker responsible for the syndrome.
