The correct answer is: Query templates can be edited to include relevant dimensions and metrics for your use case

Explanation: The statement is true: Query templates in the instructional query library can be edited to include relevant dimensions and metrics for your use case.

“Instructional queries are meant to serve as starting points for analysts. Each query can be customized for your brand or advertiser by editing dimensions, filtering conditions, or the set of metrics being selected. … These templates are meant to be adapted for different business needs and analysis requirements by modifying the SQL before running the query.”
