Answer

The correct option is To remove larger particles and debris. This answer is correct because it matches the approved learning objective to give reasons for the steps used to produce potable water in the subtopic Potable water.

Explanation

The correct option is To remove larger particles and debris. To remove larger particles and debris is correct because it directly supports the approved learning objective to give reasons for the steps used to produce potable water. This belongs to the subtopic Potable water 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 Potable water.

Common mistake

Common Mistake in Potable Water Production

Students often state that all steps in producing potable water are equally important without recognizing the specific reasons for each step.

Do not treat this as a general statement about potable water. Instead, answer by clearly linking the correction to give reasons for the steps used to produce potable water in Potable water. This keeps the response inside Using the Earth's resources and obtaining potable water and prevents a vague or off-topic GCSE answer. The mistake to avoid is: students often state that all steps in producing potable water are equally important without recognizing the specific reasons for each step.
