If X and Y are S-expression then (X.Y) is a/an ____
S-expression
Atom
List
Predicate
Correct Answer: A — S-expression
Explanation:
In LISP programming if X and Y are S-expressions then the dotted pair (X.Y) is also considered as S-expression.
What are the basic building blocks of S-expressions?
Atoms
Lists
Numbers
Predicates
Correct Answer: A — Atoms

Atom
Error will occur
S-expression
Primitive
Correct Answer: C — S-expression
Explanation:
According to recursive definition of S-expression if S1, S2, S3... are S-expressions then list: (S1 S2 S3 ....) is also an S-expression. S-expression is short form of symbolic expressions.
