1 / 15

Which statement best describes the purpose of decomposing a complex problem in computational thinking?

A) To increase the size of the original problem for better understanding

B) To solve all parts of the problem simultaneously without structure

C) To break a complex problem into smaller, manageable sub-problems

D) To remove the need for algorithms in problem solving

A student is designing a school management system; which approach best represents proper decomposition of the project?

A) Writing all code in a single file without planning modules

B) Copying existing software and modifying its interface only

C) Dividing the system into attendance, grading, and fee management modules

D) Focusing only on database design and ignoring other components

3 / 15

When solving a transportation system problem, which action reflects effective decomposition of the system?

A) Treating the entire traffic system as one single process

B) Ignoring traffic signals and focusing only on vehicles

C) Randomly analyzing road problems without categorization

D) Separating the system into routes, signals, vehicles, and timing units

4 / 15

Why is decomposition considered the first step in computational problem-solving processes?

A) Because it directly produces the final program output

B) Because it eliminates the need for debugging later

C) Because it helps understand complexity by breaking it into smaller parts

D) Because it replaces the need for abstraction completely

5 / 15

Which of the following best demonstrates decomposition when planning a school event program?

A) Deciding everything at the last minute without preparation

B) Assigning all responsibilities to a single person

C) Only focusing on budgeting and ignoring other activities

D) Separating tasks into decoration, invitations, food, and scheduling

6 / 15

A developer is building a calculator application; which decomposition strategy is most appropriate?

A) Ignoring input validation and focusing only on output display

B) Combining all mathematical operations into a single unclear function

C) Dividing operations into addition, subtraction, multiplication, and division functions

D) Writing random code blocks without structuring functions

7 / 15

Which situation incorrectly represents decomposition in problem-solving?

A) Treating all sub-problems as one combined unsolved task

B) Dividing a problem into logical sub-parts

C) Solving each sub-problem independently

D) Assigning different tasks to different modules

8 / 15

In software design, what is the main advantage of breaking a system into smaller modules?

A) It eliminates the need for collaboration among developers

B) It makes the system more confusing and harder to debug

C) It reduces the need for any planning before coding

D) It improves clarity, testing, and maintenance of each part

9 / 15

Which example best reflects decomposition in solving a biological data analysis problem?

A) Treating all data as one large unorganized dataset

B) Separating data into species, habitat, and population categories

C) Using only manual calculations without structure

D) Ignoring patterns and directly guessing results

10 / 15

When a large problem is decomposed, what is the expected result of each sub-problem?

A) A duplicate of the original problem

B) A completely unrelated solution without connection

C) A random output that does not affect final solution

D) A smaller task that contributes to solving the overall problem

11 / 15

A weather forecasting system is being designed; which decomposition is most logical?

A) Combining temperature, humidity, and wind into a single unstructured variable

B) Using only manual observations without system design

C) Separating weather data into temperature, humidity, pressure, and wind speed modules

D) Ignoring data collection and focusing only on final prediction

12 / 15

What is the main risk of not applying decomposition in complex problem-solving?

A) The solution becomes automatically optimized

B) The system becomes too simple to analyze

C) The problem becomes harder to manage and error-prone

D) The problem becomes easier to solve directly

13 / 15

Which of the following best describes decomposition in algorithm design?

A) Avoiding the use of functions or procedures

B) Writing one long sequence of instructions without structure

C) Breaking an algorithm into smaller logical steps or modules

D) Removing decision-making steps from the process

14 / 15

A student is creating a video game; which decomposition approach is most effective?

A) Copying another game without modification

B) Ignoring design and focusing only on coding

C) Treating graphics, sound, and gameplay as a single combined task

D) Separating game into gameplay mechanics, graphics, sound, and controls

15 / 15

Which statement best explains why decomposition improves problem-solving efficiency?

A) It forces all solutions to be identical

B) It removes the need for any logical thinking

C) It allows solving multiple smaller parts independently and faster

D) It increases the complexity of the problem intentionally
