Tracy needs to draw a circle inside a square.

Question

Which of the following programs solves the problem at the highest level of abstraction? (Assume all functions being used have been previously defined.)

a
forward(50)
left(90)
forward(50)
left(90)
forward(50)
left(90)
forward(50)
left(90)
forward(25)
circle(25)
b
draw_square()
draw_circle()
c
draw_square()
forward(25)
circle(25)
d
for i in range(4):
forward(50)
left(90)
forward(25)
circle(25)

Answer 1

The program that solves the problem at the highest level of abstraction is:

b

draw_square()
draw_circle()

This option expresses the drawing of the square and the circle as high-level operations (functions) rather than detailing the individual movements and directions required to perform those tasks. It encapsulates the drawing actions into comprehensible functions, making it clear that Tracy wants to draw a square and a circle without getting into the specifics of how to execute each drawing step.
