Final answer:
License A does not allow an individual to perform secondary containment testing because it does not provide the necessary authorization for this type of testing.
Step-by-step explanation:
In this case, License A does not allow an individual to perform secondary containment testing. This is because secondary containment testing is typically performed in laboratories that deal with dangerous/exotic agents with a high risk of life-threatening disease, which are usually subject to the highest level of biosafety precautions. When working with such agents, it is necessary to have special precautions in place, such as biohazard warning signage, self-closing double doors, and clothing changes. License A, therefore, does not provide the necessary authorization for this type of testing.
