Flaw here: I thought it was "so stretching reduces only the severity of your injuries and not the likelihood of injury"

Instead the flaw was "Ppl who stretch are more injury prone. stretching does reduce the likelihood of injury. it does it to the point where ppl who stretch have reduced their injury likelihood to the point where they now have reached the same likelihood of injury as non-stretchers."

The latter is probably easier to do than the former; rather than refuse the idea that stretching reduces injury, see how it still potentially could be true. Another flaw I want to be more aware of is the idea of "change in vs. rate".

Is it valid that I took out option E simply because I didn't like that it was giving me oppositeto what the question stem said? (eg. you should be allowed to choose vs. no one should be denied from choosing).
