Question

cte is more severe when...
a men play football longer and therefore have a greater tau buildup.
b men play football longer and have depleted the tau in their brains.
c players receive blows to the head at a younger age.
d players receive one big blow to the head that permanently damages tau.

Explanation:

Chronic Traumatic Encephalopathy (CTE) is a neurodegenerative condition linked to repetitive head trauma. Research shows that earlier onset of head impacts (at a younger age) is associated with more severe CTE progression, as the developing brain is more vulnerable. Option A is incorrect because duration of play alone is not the key factor over early exposure; B is wrong because CTE involves tau buildup, not depletion; D is incorrect because CTE is driven by repeated small impacts, not a single large blow.

Answer:

C. players receive blows to the head at a younger age.
