Final answer:
The percentage of USM on-campus housing constructed since 2001 cannot be determined with the data provided as no relevant information on construction dates or percentages for USM housing is available.
Step-by-step explanation:
The inquiry concerning the proportion of on-campus housing at the University of Southern Maine (USM) built post-2001 remains unanswerable based on the available information. The provided details lack any explicit data pertaining to the construction chronology or the proportional breakdown of on-campus housing at USM. Consequently, discerning the percentage of housing developed since 2001 becomes an insurmountable task in the absence of supplementary context or data.
The omission of specific information regarding construction dates or proportional figures precludes any definitive response to the query. Without a clear understanding of when on-campus housing structures were erected and in what proportions, it remains impossible to calculate the percentage attributable to post-2001 construction. The lack of granularity in the provided information underscores the importance of additional data to draw accurate conclusions regarding the temporal distribution of on-campus housing development at USM. In essence, a comprehensive understanding of the construction history is imperative for addressing inquiries regarding the percentage of on-campus housing built since 2001.
