Final answer:
The game "Twenty Questions" illustrates the problem-solving method of binary search, where each question aims to halve the remaining possible answers to identify the correct object.
Step-by-step explanation:
The game "Twenty Questions" is a classic example of a problem-solving method. In this game, one player thinks of an object, and the other player has up to twenty yes-or-no questions to determine what that object is. This game illustrates the binary search strategy.
In a binary search, each question is used to eliminate half of the remaining possibilities, which significantly cuts down on the number of required steps to reach a solution. This is similar to how search engines categorize and retrieve information using algorithms.
Through a series of increasingly specific questions, players are employing a methodological approach to narrow down the unknown entity, much like a computer algorithm processes data to find a specific result. Therefore, the answer to the question is C) Binary search.
