Incorrect. While such injuries are "very likely" for beginners mimicking experts, that doesn't mean that the injuries aren't also likely for experts in general. There could be other ways that these actions lead to such injuries.

Correct. Argument or Facts:
Facts

Question Type:
Must Be True

Stimulus Summary:
Kickboxing is more dangerous than many other forms of exercise. Overextending when matching expert high kicks can lead to many injuries.

Answer Anticipation:
Two things to note here. First, the opening statement is a comparison, but it's very weak. Kickboxing is more dangerous than "many" other types of exercise, which is very weak. We have no idea what types of exercises fall into that safer category, so we should be wary of answers that are based on this statement.

The second statement, however, is much stronger—it's causal, and it has some force behind it ("very likely"). We should focus on that statement as we work through the answers, as we can draw some inferences about situations where the cause is or isn't present based on it.

Answer Explanation:
If matching the high kicks of experts leads to injuries, then avoiding doing that should reduce injuries. This answer highlights a unique aspect of causality compared to conditionals—if you reduce a cause, you should see a reduction in the effect, which is a form of a negation, but not illegal with this type of logic.

Key Takeaway:
Be careful of weak or non-specific comparisons on a Must Be True question. They can feel as if they support many answer choices that bring up things that don't necessarily fall into the category being compared.

Incorrect. While trying to match expert high kicks is noted as a "very likely" source of injury, there are potentially others, as well.

Incorrect. While the Instructor does note that kickboxing aerobics is highly risky compared to "many" forms of exercise, there's no discussion of which forms those are. It's possible that non-high kicking exercises all fall into the quite dangerous camp. Additionally, this answer is about other types of aerobic exercise, whereas the comparison in the stimulus is to many forms of "exercise," further distancing that statement from this answer.

Incorrect. While those who attempt these kicks are "very likely" to injure themselves, that's not the same as saying that it's "very likely" anyone in these classes will injure themselves, which would be required to support this answer. It's possible that only a small subset try those high kicks, but almost all who do injure themselves.
