The correct response that captures the difference in ideas regarding the impact of video games on mental health from the two texts is:
"Video Games Should Be Considered a Sport" claims video games harm mental health, but "Gamers are Not Athletes" explains why eSport gamers may have poor mental health.
In the first source, while it emphasizes the mental agility and reflexes of gamers, it does not directly address mental health in a negative context. On the other hand, the second source explicitly states that video games can have negative effects on the brain and can lead to neurological disorders and addictions, suggesting a detrimental impact on mental health.
