Final answer:
A stroke is caused by a clot blocking the blood supply to the brain.
Step-by-step explanation:
False. A stroke is caused by a clot blocking the blood supply to the brain, not the heart. The heart is responsible for pumping blood throughout the body, while the brain receives blood through a network of blood vessels. When a clot obstructs a blood vessel in the brain, it can lead to a stroke.
