@nivensdc Happy to help!

(B) is directly supported by the passage's statement that "such overextension" - which it notes "often leads to hip, knee, or lower-back injuries" - "is very likely to occur when beginners try to match the high kicks of more skilled practitioners." With this statement, we are able to conclude that beginners should not try to match the high kicks of skilled practitioners if they are looking to reduce injury. This is because we know that attempting to match these is "very likely" to lead to overextension, which causes injury.

(A) is incorrect because the passage only talks about the likelihood of beginners becoming injured, not skilled practitioners. Therefore, we cannot assume.
(C) is incorrect because we do not know that matching skilled practitioners' high kicks is the only act that causes beginner injures.
(D) is incorrect because we only know that kickboxing aerobics is highly risky as compared to "many forms of exercise." It could be very well be the case that there are some forms of aerobic exercise that do not involve high kicks that fall outside the scope of the "many" and are more dangerous.
(E) is incorrect because we cannot say that most beginners experience injuries from a certain situation (imitating the high kicks of skilled practitioners) just because this situation is "very likely" to lead to injuries. It could be the case that most beginners are never put in this situation.

Does that help? Let us know if you have any additional questions!
