Which term best describes something that has emitted flashes of light?

• A. Scintillated
• B. Presaged
• C. Necrosis
• D. Quarantine

Answer: (A)

The concept tested is a specific verb meaning to flash or sparkle light. Scintillate means to emit flashes of light or to sparkle; when describing something that has done so, the past participle form scintillated fits perfectly. For example, fireworks or stars can scintillate, and in the right context, you’d say they scintillated.

Presaged means to foreshadow or predict something that will happen; it’s about foretelling, not light. Necrosis refers to tissue death, a medical term with no relation to emitting light. Quarantine means isolation to prevent the spread of disease, also unrelated to light emissions. So scintillated is the best choice because it directly conveys having emitted flashes of light.
