Narrow Extended Essay scope and feasibility

A student is testing the feasibility of an EE about "whether vitamin C changes during juice storage" using school-lab titration data and storage-time records. Choose the route that narrows the scope responsibly. Select the scope limit, evidence access, word-count control, and scope risk. Then answer this in your own words: why would this route keep the EE research process focused and authentic? AI will analyse your reasoning, evidence, research judgement, documentation, reflection quality, and expression.
