Which of the following best defines "reasonably contiguous" in relation to campus geography?

"Reasonably contiguous" in the context of campus geography refers to properties that are geographically close enough to the main campus to be considered part of the campus for reporting and safety purposes. This definition allows institutions to include certain off-campus locations that are utilized for educational purposes within a specified distance, typically up to a one-mile radius. This is significant for compliance with Clery Act reporting requirements, which mandate that institutions report crimes occurring on or near campus.

Choosing properties within a one-mile radius recognizes that not all educational activities occur directly on the main campus. This definition supports the idea that safety and reporting obligations extend to areas where students frequently gather or participate in campus-affiliated activities.

Other options do not accurately capture the intended meaning of "reasonably contiguous." For instance, buildings owned by the institution regardless of distance lack the necessary proximity to be considered contiguous, while limiting the definition to only adjacent buildings or classes held off-campus does not account for the broader scope of educational activities that the Clery Act aims to monitor.
