Step-by-step explanation:
The subject of the question pertains to the effectiveness and correct use of athletic mouthguards in preventing concussions, which falls under the category of Health. In response to the student's question, both statements are true: Athletic mouthguards can help in preventing concussions, but they must be worn correctly and consistently to be effective. The importance of protective gear in sports is underscored by various measures taken by organizations such as the NCAA and NFL to improve safety protocols, including the use of helmets with higher safety ratings which have been linked to reduced concussion rates. However, athletic mouthguards, while they contribute to overall mouth protection and may reduce the severity of impact, are not a panacea for concussion prevention and must be supplemented with other safety precautions and equipment.
