MCQs on Computational Thinking

Problem solving is similar to which of the following?

• Playing a game

• Being a detective

• Cooking food

• Painting a picture

What is the first step of problem solving?

• Try it out

• Choose the best solution

• Understand the problem

• Check the result

In the school bus example, which is the best solution if it is raining?

• Walk to school

• Take an auto-rickshaw

Computational thinking involves:

• Only using a computer to solve problems

• Thinking step-by-step like a computer

• Memorizing all solutions

• Ignoring real-life problems

Which is NOT one of the 4 main parts of computational thinking?

• Decomposition

• Pattern Recognition

• Abstraction

• Debugging

Decomposition means:

• Ignoring extra details

• Breaking a problem into smaller parts

• Finding patterns in problems

• Writing code

Which is an example of decomposition?

• Decorating a room and inviting guests at the same time

• Making a guest list, buying snacks, decorating, arranging games, and cutting the cake

• Guessing the solution without planning

• Doing everything without dividing tasks

One advantage of decomposition is:

• Problems become more confusing

• Saves time and effort

• Increases mistakes

• Makes teamwork harder

Pattern recognition is useful because it:

• Makes it harder to solve problems

• Helps us repeat mistakes

• Helps us avoid mistakes and save time

• Avoids using past experience

Which of the following is NOT a real-life application of pattern recognition?

• Speech recognition

• Handwriting recognition

• Image recognition

• Washing clothes
