Research consistently links regular aerobic exercise to improved cognitive function in older adults. Studies show that individuals who engage in moderate exercise at least three times per week demonstrate significantly better memory consolidation and executive function than sedentary peers, even after controlling for baseline health status.

While the cognitive benefits of exercise in older adults are well documented, recent studies suggest that the type of exercise matters considerably. Resistance training, rather than aerobic activity, appears to produce stronger gains in prefrontal cortex function — the region most associated with planning and decision-making.
Step 1 — Author 1's claim
"Regular aerobic exercise improves cognitive function in older adults."
Step 1 — Author 2's claim
"Exercise benefits cognition, but resistance training is better than aerobic for prefrontal cortex gains."
Step 2 — Relationship: Partially agree. Both agree that exercise benefits cognition in older adults. But they diverge on type: Author 1 focuses on aerobic; Author 2 argues resistance training is more effective for one cognitive domain.
Based on the texts, both authors would most likely agree that:
AAerobic exercise is the most effective form of physical activity for older adults' cognitive health— Author 2 explicitly disagrees with this
BResistance training produces no meaningful cognitive benefits in older adults— Author 1 doesn't address resistance training at all; can't attribute this to Author 1
CPhysical exercise of some kind is associated with cognitive benefits in older adults✓ Both authors accept this — it's the common ground they share
DThe cognitive effects of exercise in older adults remain entirely unproven— both authors treat the benefits as established; this contradicts both texts
Key insight: C is the only choice that both authors explicitly support. A is a one-text answer (Author 1's position, but Author 2 challenges it). B contradicts Author 2's actual finding. D contradicts both texts. Always find the choice that is anchored in BOTH texts.
