Which term describes solving problems by following a fixed sequence of steps that guarantees a correct answer if applied correctly?

• A. Algorithm
• B. Mental Set
• C. Heuristic
• D. Convergent Thinking

Answer: (A)

The main idea tested is a fixed, step-by-step method that guarantees a correct result if followed correctly. That is what an algorithm is: a precise sequence of instructions designed to solve a problem. Each step is defined, there’s a clear starting point, and if you carry out the steps in order, you’ll reach the solution. A heuristic, by contrast, uses rules of thumb that speed up solving but don’t guarantee correctness. A mental set refers to sticking to familiar strategies and can prevent finding the right approach. Convergent thinking describes focusing on one correct answer rather than how you reach it, but it’s about the thinking style, not a predefined method. So the term that fits is algorithm.
