Which term best describes a situation where multiple live mice are present inside a unit during inspection?

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

Answer: (C)

When describing what you find, you want a term that communicates how big the problem is, not just that something was noticed. If multiple live mice are present inside a unit, the issue isn’t a single stray animal or a minor nuisance—it shows a broader infestation within that space. The word that best captures that level of scope and severity is extensive. It signals that the pest problem is widespread enough to require more comprehensive remediation and monitoring.

The other terms don’t convey the same meaning about how far-reaching the condition is. Evidence would refer to proof you collected, observation is the act of seeing something during the inspection, and a deficiency is the category of the finding itself without necessarily describing its breadth. But when there are several mice, you’re describing a problem of extensive scope within the unit.
