A student is writing a research report for her science class about ideas for reducing head injuries in football. The student must use sources that are credible, trustworthy, and relevant for the topic.

Which of these is MOST LIKELY a credible and trustworthy source that is relevant for the topic?
A.

an article in a sports medicine journal about studies that have been done on practices that have lowered head injury rates
B.

a blog written by a football player who is not in favor of making changes to the rules or equipment of the sport
C
.

an entry in an online encyclopedia about the history of football and how head protection has changed over time
D.

a petition signed by 15,000 football players who want steps to be taken to reduce the number of head injuries in football

A. an article in a sports medicine journal about studies that have been done on practices that have lowered head injury rates

The MOST LIKELY credible and trustworthy source that is relevant for the topic of reducing head injuries in football is A. an article in a sports medicine journal about studies that have been done on practices that have lowered head injury rates. This source is likely to provide evidence-based research on effective measures to reduce head injuries in football.

The most likely credible and trustworthy source that is relevant for the topic is option A, an article in a sports medicine journal about studies that have been done on practices that have lowered head injury rates.

To determine the credibility and trustworthiness of a source, it is important to consider factors such as the author's qualifications, the reputation and credibility of the publication or platform, and the presence of verifiable references or citations. In this case, a sports medicine journal is a reputable source as it is a specialized publication in the field of medicine that undergoes a rigorous peer-review process before publishing articles. This indicates that the information in the article has been scrutinized by experts in the field, ensuring its accuracy and reliability.

Furthermore, the article specifically focuses on studies that have explored practices to reduce head injury rates in football. This makes it highly relevant to the research topic and suggests that it will provide valuable and evidence-based information for the student's research report.

On the other hand, option B, a blog written by a football player who is not in favor of making changes to the rules or equipment of the sport, may not be a credible or trustworthy source. While it can provide insights and perspectives, it may be biased and lack the scientific rigor and expertise that a peer-reviewed sports medicine journal would provide.

Option C, an entry in an online encyclopedia about the history of football and how head protection has changed over time, can provide a general background on the topic but may not provide the specific and up-to-date information needed for a research report. Online encyclopedias can be a good starting point for background information, but they may not always be the most reliable source for in-depth research.

Option D, a petition signed by 15,000 football players who want steps to be taken to reduce the number of head injuries in football, although it may indicate the existence of a concern, doesn't necessarily provide credible or trustworthy information. Petitions are a form of public expression and can be influenced by various factors such as personal opinions, emotions, or motivations.
