Which control structure repeats a question and action until it's no longer required?

Which control structure repeats a question and action until it's no longer required?

• A. Structured programming
• B. Loop structure
• C. Modular construction
• D. Connector symbol

Answer: (B)

A loop structure is designed for repetition. It keeps asking a question and performing the associated action over and over as long as a condition remains true, stopping when that condition becomes false or when the task is no longer needed. This is exactly what “repeat a question and action until it’s no longer required” describes, since the flow repeats the steps until the stopping criterion is met. In practice you might implement this with a while loop or a do-while loop: ask for input, process it, then check whether you should continue. The other ideas address different aspects of programming — structured programming focuses on organizing code into clear blocks, modular construction is about dividing a program into modules, and a connector symbol is used in diagrams to show flow between parts rather than to drive repetition.
