Summary
Kickboxing aerobics is a highly risky form of exercise. Overextending while kicking can cause hip, knee, or lower-back injuries. Overextension is likely to occur when beginners try to match skilled kickboxers' high kicks.
Strongly Supported Conclusions
To reduce the risk of kickboxing injuries, people should avoid overextending while kicking.
Kickboxing beginners can reduce their injury risk by not seeking to imitate experts' high kicks.

a
Skilled practitioners of ██████████ ████████ ███ ████████ ██ ██████████ ████████ ████ █████████████ █████ ████████
This answer is unsupported. The aerobics instructor does not give us any information about the likelihood of skilled practitioners experiencing injuries.
b
To reduce the ████ ██ █████████ █████████ ██ ██████████ ████████ ██████ █████ ██████ ██ █████ ███ ████ █████ ██ ████ ███████ ██████████████
This answer is strongly supported. We know that overextension can cause injury, and that overextension is likely when beginners try to match high kicks. So we can infer that reducing this kind of imitation would reduce the number of injuries.
c
Beginners at kickboxing ████████ ████ ███ ██████████ ████████ ██ ████ █████ ██████ ██ █████ ███ ████ █████ ██ ████ ███████ ██████████████
This answer is unsupported. We don’t know if overextending while kicking is the only cause of injury to beginners. It is possible that beginners could experience injury some other way.
d
Kickboxing aerobics is ████ █████ ████ █████ ██ ███████ ████████ ████ ██ ███ ███████ ████ ██████
This answer is unsupported. We know that kickboxing aerobics is more risky than "many" forms of exercise, but we don’t know how it specifically compares to other aerobic exercise forms without high kicks.
e
Most beginners at ██████████ ████████ ██████████ ████████ ████ ██████ ██ █████ ███ ████ █████ ██ ████ ███████ ██████████████
This answer is unsupported. We do not know whether most beginners will overextend while kicking. "Likely" in the stimulus is not equivalent to "most."
