Pick an option and check your answer. The full worked answer is below either way.
Answer
(a) Both A and R are True.
BOTH STATEMENTS ARE TRUE.
The sympathetic system produces the FIGHT-OR-FLIGHT response, preparing the body for sudden and violent action in an emergency. Accelerating the heartbeat is one of the ways it does so, since faster circulation delivers more oxygen and glucose to the muscles.
Its other effects all serve the same purpose: breathing rate rises, the bronchi and pupils dilate, blood is diverted from the gut to the skeletal muscles, and digestion slows.
NOTE THE OPTION FORMAT in this year’s paper. It offers only four plain combinations — both true, one true, the other true, both false — without asking whether R EXPLAINS A. Other years (including 2026) split the "both true" option in two. Read the options given before assuming which format you are in.
Both A and R are True.
