Q1. Nebla-Implications are often used in fuzzy logic because they:

1. Are simpler than classical implications
2. Do not require t-norms
3. Provide a way to handle partial truth values
4. Can only be applied to Boolean variables

Correct answer: Provide a way to handle partial truth values

Q2. In fuzzy implication, for any fuzzy number x, x·(η(x)) is equal to:

1. x
2. 1 − x
3. x − x²
4. x²

Correct answer: x − x²

Q3. If A(x) = 0.3 and B(x) = 0.35 are two fuzzy sets, then max(A, B) =

1. 0.5
2. 0.3
3. 0
4. 0.35

Correct answer: 0.35

Q4. What is the primary characteristic of Nebla-Implications in fuzzy logic?

1. They use only the minimum operator
2. They are defined based on a continuous t-norm
3. They are defined based on probabilistic interpretations
4. They use only the maximum operator

Correct answer: They are defined based on a continuous t-norm

Q5. Which of the following is a common method for calculating the distance between two fuzzy sets?

1. Euclidean distance
2. Minkowski distance
3. Hamming distance
4. All of the above

Correct answer: All of the above
