@sevanb As the answer explanation states, the transit scorecard indicates a demolition waste and excavation management plan is required. Refer to the LEED Transit reference in the case study and navigate to the section titled Materials and Resources.
In addition to reviewing the correct answer explanations, it is also very helpful to review the incorrect answer explanations. This gives you a better understanding of the context and why one answer may be a better choice than another.
Hope this helps!
