What term is used for a group of elements arranged to fulfill a specific purpose, with interactions among parts?

• A. Entity
• B. System
• C. Arrangement
• D. Whole

Answer: (B)

A system is a group of parts that interact with each other to accomplish a specific purpose. The key idea is that the parts influence one another, and their interactions create functions or properties that the parts wouldn’t have on their own. For example, the circulatory system includes the heart, blood, and vessels working together to move blood and supply oxygen and nutrients throughout the body. An entity is just a single thing, not necessarily a network of interacting parts. An arrangement emphasizes order without signaling functional interactions, and a whole refers to the entire object without implying coordinated parts working toward a purpose.
