Incorrect. The conclusion here could be justified, but it would need to be shown that no tasks normally carried out pose a safety risk, not only some of them as this answer states.

Correct. Argument or Facts:
Facts

Valid or Flawed:
N/A

Question Type:
Must Be True (Principle)

Stimulus Summary:
not Incompetence in normal tasks poses safety risk → not Occupation subject to licensing

Answer Anticipation:
Very wordy principle! We used "unless" as "if not" and diagrammed it accordingly. If you used "unless" as a necessary indicator where you have to negate the sufficient condition, you should have ended up with the contrapositive of our statement.

Looking at the principle as we summarized it, we should consider whether it's likely to be used in its current form or in the contrapositive in the scenarios from the answer choices. Since it's much more likely that an answer will conclude that an occupation shouldn't be subject to licensing based on whether it can pose health/safety risks, our summary should work. (The contrapositive would allow for an answer to conclude that incompetence in normal tasks poses a danger based on premises about whether the job should be subject to licensing—which sounds backwards.)

Let's find an answer where there's no risk to safety and thus there should be no licensing requirement for the occupation! Note that the principle can't justify a conclusion that there should be licensing requirements for an occupation, so we can rule those right out.

Answer Explanation:
This answer concludes that a profession shouldn't have licensing requirements based on a lack of potential safety risks posed by the normal tasks of that occupation. That's justified by the principle, so this is the correct answer.

Key Takeaway:
Once you get the principle diagrammed out in a Must Be True (Principle) question, you know what conclusions can be supported based on it—arguments using that principle can conclude the necessary condition based on the presence of the sufficient. As such, you can rule out any answer that tries to conclude the sufficient condition, or the negation of the necessary condition—they can never be validly supported with that principle.

Incorrect. The principle doesn't provide sufficient conditions under which to conclude that an occupation should be subject to licensing requirements, so this answer is incorrect.

Incorrect. The principle doesn't provide sufficient conditions under which to conclude that an occupation should be subject to licensing requirements, so this answer is incorrect.
