Concept:Conceptual knowledge means understanding the meaning of ideas and being able to apply them, like comparing or contrasting different concepts.
Explanation:Questions that test conceptual knowledge require students to use their understanding of definitions and principles.
Option B asks to distinguish between economic development and sustainable development. This needs a clear grasp of both concepts to explain the differences.
Option E asks to differentiate between subsistence farming and commercial farming. Again, the student must know what each type means to compare them.
Options A, C, and D ask about specific facts or personal opinions. They do not directly test the ability to analyse or compare concepts.
Therefore, only statements B and E assess conceptual knowledge.
Answer:C. B and E
