Final answer:
In the legal context, the appropriateness of a test may be challenged without certain safeguards in place, similar to exceptions in the exclusionary rule.
Step-by-step explanation:
In the legal context, the necessity and appropriateness of a test could be successfully challenged if certain safeguards are not in place. This can be compared to exceptions in the exclusionary rule, where evidence obtained without the necessary legal procedures may still be admissible under the 'good faith' exception or 'inevitable discovery' exception. These exceptions allow for flexibility in the legal system while still maintaining fairness and justice.
