Explanation
The correct option is To judge the significance of resource data. To judge the significance of resource data is correct because it directly supports the approved learning objective to use orders of magnitude to judge the significance of resource data. (MS 2h). This belongs to the subtopic Using the Earth's resources and sustainable development within Using the Earth's resources and obtaining potable water, so the explanation must stay tied to that curriculum context. The other options are incorrect because they either do not answer this learning objective, use a vague statement, or move away from Using the Earth's resources and sustainable development.
Common mistake
Misunderstanding Orders of Magnitude
Students often confuse orders of magnitude with simple numerical values, failing to recognize that orders of magnitude represent a scale of tenfold differences.
To fix this, practice converting numbers into scientific notation and understand that each increase in order of magnitude represents a tenfold increase.
