To assess students' knowledge of principles and rules, teachers should supply:

The choice that suggests supplying situations needing identification of principles in everyday problems is correct because it allows students to actively engage with the material in a practical context. This method encourages critical thinking, as students must apply their knowledge of principles and rules to real-world scenarios rather than merely recalling information. By encountering problems that mimic everyday situations, students can demonstrate their understanding and ability to use these principles effectively, promoting deeper learning.

Other options don't provide the same level of engagement. Simple, straightforward questions might assess recall but do not challenge students to think critically or apply their knowledge. Multiple-choice questions without context limit the ability to assess understanding meaningfully, as they do not require the student to connect principles to real-life situations. Simplified scenarios with clear answers may not fully capture the complexities involved in applying principles, leading to a surface-level understanding rather than a deeper grasp of the subject matter.
