The director of a secondary school where many students were having severe academic problems impaneled a committee to study the matter.
Conclusion
Refraining from sports will guarantee that these students do well academically.
Evidence
The committee said these students were having academic problems because they spent large amounts of time on sports and too little time studying.
Evaluate
This seems more like a "argue the anti-conclusion" argument then a "search for missing links" one. The main evidence is a committee's report, so we could have practical concerns about how trustworthy that data is.
The harshness of the conclusion should stick out to us.
It's easy to defeat that conclusion with just one counterexample. Can we think of a story where a student stops spending large amounts of time on sports but still doesn't do well academically?
Sure -- maybe now that they have time to study, they find out they have a learning disability that makes it hard to do well academically. Maybe now that they have hours in the week free from sports, they spend it on TikTok or guitar or hiking, but still not on studying.
Goal
Let's look for an answer saying, "We're assuming the committee's report is accurate/trustworthy" or one ruling out a storyline where students still don't do well academically, even though they now have more time available to study.
