Read the below passage and answer the questions.

Fuzzy Logic is a mathematical approach to reasoning that is designed to handle the concept of partial truth, where the truth value may range between completely true and completely false. Unlike traditional binary logic, which operates on precise values (0 or 1), fuzzy logic allows for a degree of uncertainty and vagueness, making it more suitable for real-world applications where human reasoning is not always black and white.

In fuzzy logic, variables can have a range of values, represented by membership functions. These functions define how each point in the input space is mapped to a degree of membership between 0 and 1. For instance, in a temperature control system, the temperature can be classified as "cold," "warm," or "hot," each with a corresponding degree of membership that reflects how closely the current temperature aligns with each classification.

Fuzzy logic is widely used in various fields, including control systems, artificial intelligence, and decision-making processes. It enables systems to make decisions based on imprecise data and allows for more flexible and human-like reasoning. Applications of fuzzy logic can be found in areas such as automated control of appliances, climate control systems, and expert systems.
