Option A: “Schwartz has a larger population than Talsberg does.”
Explanation:
If Schwartz simply has more people, then more gym memberships don’t necessarily mean each person is exercising more. The higher total could be due to population, not frequency of exercise.
Does it weaken?
✅ Yes. It offers an alternative explanation for the statistic — weakens the link between memberships and actual exercise frequency per citizen.
⸻
Option B: “Most citizens of Talsberg work in Schwartz and have memberships in gyms there.”
Explanation:
If Talsberg residents are the ones buying gym memberships in Schwartz, then Schwartz’s high gym membership numbers aren’t actually due to Schwartz citizens.
Does it weaken?
✅ Yes. Undermines the assumption that Schwartz citizens are the ones exercising.
⸻
Option C: “The average price of a gym membership is lower in Schwartz than it is in Talsberg.”
Explanation:
Cheap memberships may lead to more people buying them, even if they don’t use them much. So the count of memberships may be inflated.
Does it weaken?
✅ Yes. Breaks the link between more memberships and more actual exercise.
⸻
Option D: “A large, free community gym open to all is available to the citizens of Talsberg.”
Explanation:
Talsberg citizens may be exercising without needing to buy memberships at all — so fewer memberships doesn’t mean less exercise.
Does it weaken?
✅ Yes. Undermines the idea that fewer memberships = less exercise.
⸻
Option E: “The average citizen of Schwartz spends less time at the gym per week than does the average citizen of Talsberg.”
Explanation:
At first glance, this might seem to weaken — but look closely. The conclusion is about frequency (how often), not duration (how long).
Schwartz citizens could be going to the gym more often, but for shorter periods each time.
Example:
• Schwartz: goes 5 times/week, 20 mins each time.
• Talsberg: goes 2 times/week, 1 hour each time.
In this case, Schwartz citizens exercise more frequently, even though they spend less time overall.
Does it weaken?
❌ No. It talks about time, not frequency. So the conclusion still stands.
