[Assess students' ability to design a comprehensive randomized controlled trial protocol for a culturally tailored, multi-component intervention (community-based physical activity, dietary counseling, behavior-change techniques) to reduce type 2 diabetes incidence in high‑risk urban minority adults. The protocol should specify population and recruitment, detailed intervention and cultural adaptations, theoretical framework linking behavior-change mechanisms, primary and secondary outcome measures (clinical, behavioral, process, equity), sample size and power justification, randomization and blinding approach, statistical analysis plan (including intention-to-treat, handling missing data, subgroup and sensitivity analyses), implementation fidelity, cost-effectiveness and scalability assessment, and ethical/community-engagement considerations. Provide a concise protocol outline and justify key methodological choices.]
