Which term means tool or piece of equipment?

• A. Device
• B. Diagnosis
• C. Dysfunction
• D. Equilibrium

Answer: (A)

This question tests understanding of a word that names a tool or instrument used to perform a function. A device is a thing designed for a specific purpose and is commonly used to mean a tool or piece of equipment—think of medical devices like a stethoscope or a handheld gadget. The other terms refer to different ideas: diagnosis is identifying a disease or condition; dysfunction is impaired functioning; equilibrium is a state of balance. Therefore, the word that best fits the description is device.
