Write a Common Lisp program that clearly shows the difference between static and dynamic scoping

What characteristics of Common Lisp and Scheme make them essentially polar opposites?

Suppose that a programming language uses dynamic scoping. Consider the following code segment in C-like syntax. void func1(void); /* prototype */ void func2(void); /* prototype */ void func3(void); /* prototype */ void main() { int a, b, c; ... } void func1() { int b, c, d; } void func2() { int c, d, e; } void func3() { int d, e, f; } For each of the following calling sequences, determine which variables are visible during the execution of the LAST function called. In your answer, include, for each visible variable, the name of the functions in which it is declared. (1) main → func1 → func3→ func2 (fun2 is the last function called) (2) main → func2 → func3 → func1 (funl is the last function called)

Define concrete and abstract syntax with example.
