A live mouse seen inside a unit during an inspection is considered which level of evidence?

• A. deficiency
• B. evidence
• C. extensive
• D. observation

Answer: (B)

The main idea is how NSPIRE classifies what an inspector finds during the inspection. A live mouse inside a unit is tangible proof that a pest problem exists, so it serves as concrete documentation of the condition. That kind of finding is categorized as evidence because it provides verifiable support for the presence of an issue. It’s not just a generic note of what was seen (which would be an observation) and it isn’t describing the extent (which would be extensive) or the formal deficiency itself. So, the live mouse is best described as evidence.
