Which term denotes disruption of blood supply to the brain, producing a stroke?

• A. Gene Therapy
• B. Cloning
• C. Cerebrovascular Accident
• D. Active Listening

Answer: (C)

The main idea tested here is naming the event where blood flow to the brain is interrupted, which is described by the medical term cerebrovascular accident. This term literally points to disruption of the brain’s blood vessels (cerebrovascular) and the occurrence itself as an accident, which together describe a stroke. A cerebrovascular accident can result from a blockage that stops blood flow (ischemic stroke) or from bleeding into the brain (hemorrhagic stroke), both leading to brain tissue damage due to lack of oxygen and nutrients. In everyday language, we simply call this a stroke, but the formal term captures the vascular cause and brain involvement. The other options refer to unrelated concepts: gene therapy aims to alter genes to treat disease, cloning creates genetically identical copies, and active listening is a communication technique.
