Food moves through a one-way processing path
A one-way processing path — each organ has one job
Match each organ to its role: mechanical breakdown, enzyme action, absorption or water recovery. Do not swap where these steps occur.
Find the tested idea
Name the biological structure, process or relationship being tested before comparing the options.
Work from the evidence
Link the structure to its function, or trace the process in its natural order. Use the stated condition rather than a memorised exception.
Verify before choosing
Use the wording, diagram and units exactly as given. Select an option only after it satisfies every stated condition.
