¿Cuál de las siguientes afirmaciones es cierta sobre el uso de consultas dentro de la biblioteca de consultas instructivas?

The correct statement is that query templates can be modified to include dimensions and metrics relevant to your use case. This is a core feature of Amazon Marketing Cloud (AMC), allowing users to adapt pre-built queries to their specific analytical needs. AMC provides instructional query templates as a starting point, and their utility comes from the ability to customize them. The other options are incorrect: "AMC users can upload queries and save them for future use" is incorrect because while users can save queries they've written or modified, the primary mechanism isn't "uploading" in the sense of importing external files; rather, it's saving within the AMC environment. "Instructional query templates cannot be modified before going live" is incorrect. The purpose of these templates is to be modified and adapted to specific analytical requirements before being run.
