1
What does t.pencolor(colors[color_index % len(colors)]) do in the starburst code?
It loops through the color list in order
It turns the turtle into a rainbow
It always sets the color to red
It chooses one random color
2
What would be a fun recursive drawing to try?
A while loop walking
A turtle eating pizza
A dancing emoji
A shrinking square
3
What is the base case in a recursive function?
The point where the function stops calling itself
The color of the turtle
The size of the turtle's shell
The first number in a loop
4
How is recursion different from a loop?
Recursion is faster in every case
Loops can only run once
Recursion is done by repeating a function call
Loops don't work with turtles
5
In the spiral loop example, what happens to length each time?
It gets reset to 0
It increases by 5
It decreases
It stays the same
6
What will happen if a recursive function has no base case?
The computer draws faster
The function stops immediately
It creates an error or runs forever
The turtle changes color
7
Which of the following is not a loop?
while True
for i in range(10)
repeat 10 times (not real Python!)
draw_spiral(length + 5)
8
What does color_index % len(colors) help with?
Coloring the background
Drawing only one color
Making the turtle bigger
Avoiding index errors when looping through colors
9
What is the purpose of t.backward(length) in the recursive starburst?
To stop the drawing
To spin the turtle
To move the turtle off the screen
To undo the forward move
10
What is recursion in Python?
A function that calls itself to solve a smaller problem
A way to repeat code using a for loop
A way to paint your turtle in a new color
A function that loops 10 times
