How should external resources be cited in Week 1 materials?

• A. A proper reference and version date
• B. A date only
• C. Without any citation
• D. A short note

Answer: (A)

Clear attribution and traceability for external resources are essential when building Week 1 materials. The best approach is to include a proper reference and a version date. A full reference identifies the resource unambiguously—author, title, source, publication year, and where to access it—while the version date shows exactly which edition or update the material is based on. This combination lets learners locate the source and understand its currency, which is important for training content that can change over time. A date alone doesn't specify the resource or its location, making it hard to verify or reuse. Without any citation, readers have no way to verify claims or credit authors. A short note lacks the detailed bibliographic information needed to identify and retrieve the source. So the most reliable and helpful choice is a proper reference paired with a version date.
