Final answer:
Convergent thinking is characterized by focusing on finding the single, correct answer to a problem, often judging multiple ideas to identify the most viable one.
Step-by-step explanation:
The best description of convergent thinking is a process that focuses on coming up with the single, well-established solution to a problem. Unlike divergent thinking, which involves creative exploration of many possible solutions, convergent thinking involves using critical thinking to judge ideas, aiming to identify the most effective solution. In a design context, after various concepts are brainstormed, convergent thinking is utilized to evaluate these ideas against set constraints and criteria to determine which one is the most viable for implementation. Therefore, convergent thinking can be described as a way of identifying which ideas have the best chance of success.
