Answer :

Final answer:

Peppermint's effect on mental sharpness should be tested in a controlled setting for validity.


Explanation:

A valid scientific claim would be tested in a controlled setting with repeated results. This means that the study on how peppermint odor increases mental sharpness should be conducted with careful control over variables and produce consistent outcomes upon repetition. For example, a study by the Smell & Taste Treatment and Research Foundation conducted experiments with floral-scented masks to analyze the impact of smell on learning, emphasizing the importance of controlled conditions for scientific validity.
