Transcribed Image Text:**Question** Using the context of an online quiz program (such as this exam, for example) give an example of a Prolog fact.
**Question:**

Which of the following is meaningful in Prolog?

- ( ) add(N1, N2)

- ( ) add[N1, N2]

- ( ) add(N1 + N2)

- ( ) add(N1, N2, N3)

**Explanation:**

This question presents four different Prolog expressions. The task is to determine which of these expressions is syntactically correct and meaningful in Prolog programming. Prolog uses a specific syntax to define predicates and expressions, and understanding this syntax is crucial for identifying the correct expression.
