Computational Thinking Quiz

A robot is programmed to pick up objects of specific colors. It picks only red and blue objects. If the robot encounters the following sequence of objects: yellow, red, green, blue, blue, red, how many objects will it pick up?

• 2

• 3

• 4

• 5

Which of the following best describes the term "decomposition" in computational thinking?

• Breaking down a problem into smaller, manageable parts

• Combining solutions to create a larger program

• Repeating steps to solve a problem

• Finding errors in a solution

In computational thinking, why is pattern recognition important?

• It ensures all errors are removed.

• It helps identify similarities to create efficient solutions.

• It breaks problems into smaller parts.

• It defines a sequence of steps to solve a problem.
