Question

which of the following excerpts from passage 1 best supports the claim that organizations are making an effort to reduce the risk of concussions in youth football?

\the issue has been debated since football became a sport in the late 19th century.\

\the national federation of state high school associations has issued new guidelines that limit the number and frequency of full - contact practices.\

\one study finds that the average number of head impacts among nine to 12 - year - olds is 378 per season.\

\the aspen institute reports that flag football, played without blocking and tackling, has grown in popularity as participation in tackle football has declined.\

Explanation:

To determine which excerpt supports the claim, we analyze each option:

• The first option talks about the debate's history, not efforts to reduce concussions.
• The second option: The National Federation of State High School Associations issuing new guidelines to limit full - contact practices is a direct effort by an organization to reduce concussion risk (as full - contact practices can lead to concussions).
• The third option just provides data on head impacts, not an effort to reduce risk.
• The fourth option discusses the popularity of flag football and decline of tackle football, but it's about participation trends, not an organization's effort to reduce concussion risk.

Answer:

B. "The National Federation of State High School Associations has issued new guidelines that limit the number and frequency of full - contact practices."
