WGU D116 INTRODUCTION TO SYSTEMS THINKING
COMPREHENSIVE TEST BANK (200
Questions)
Exam Version: 2026
SECTION 1: FUNDAMENTALS OF SYSTEMS THINKING (Questions 1-30)
1. What is the primary focus of systems thinking?
A. Breaking down a system into its smallest parts for individual analysis.
B. Understanding the interconnections and relationships within a whole system.
C. Focusing exclusively on the inputs and outputs of a process.
D. Creating linear, step-by-step solutions to problems.
Correct Answer: B
Rationale: Systems thinking is fundamentally about seeing the whole and the relationships between
its parts, rather than just the parts in isolation. Option A describes reductionism, which is the opposite.
Options C and D are too narrow and represent linear thinking.
2. Which of the following best describes a "system"?
A. A collection of independent items.
B. A set of interconnected elements that work together to achieve a common purpose.
C. A random assortment of components with no defined boundaries.
D. A single process with a clear beginning and end.
Correct Answer: B
Rationale: This is the classic definition of a system. It emphasizes the interconnectedness and the
shared purpose, which are key elements. Option A lacks the 'interconnected' aspect, C lacks purpose,
and D is a process, not necessarily a system.
, 3. In systems thinking, what is the opposite of a "closed system"?
A. A static system
B. An open system
C. A complex system
D. A simple system
Correct Answer: B
Rationale: A closed system has no interaction with its environment. An open system, conversely,
interacts with and exchanges information, energy, or matter with its external environment. This is a key
distinction in systems theory.
4. Which of these is a characteristic of a system?
A. Purpose
B. Parts
C. Relationships
D. All of the above
Correct Answer: D
Rationale: A system is defined by its purpose (or function), its component parts, and the
relationships and interconnections between those parts that enable it to achieve its purpose.
5. What is a "boundary" in a systems context?
A. A physical wall that separates the system from the outside world.
B. A decision made by leadership about what is and is not part of the system under consideration.
C. A fixed line that cannot be crossed by any element.
D. The point at which a system fails.
Correct Answer: B
, Rationale: The boundary is a conceptual distinction determined by the observer or modeler. It
separates what is included in the analysis (the system) from what is considered the external
environment. It is a decision, not a physical reality.
6. What is the "environment" of a system?
A. Everything inside the system boundary.
B. The physical surroundings where the system is located.
C. Everything outside the system boundary that interacts with the system.
D. The system's rules and regulations.
Correct Answer: C
Rationale: The environment is the external context that influences the system and is influenced by
it. It is separate from the system but is often critical to understanding its behavior.
7. What is an emergent property?
A. A property of a system that can be found in its individual parts.
B. A characteristic that appears at the system level that is not present in its individual components.
C. A goal that is defined before the system is built.
D. A simple, predictable outcome of system behavior.
Correct Answer: B
Rationale: Emergent properties are the hallmark of a system. They are novel and unpredictable
from examining only the parts. Examples include the consciousness of a brain or the happiness of a
family.
8. A car's ability to transport a person is an emergent property. Which of the following is TRUE?
A. The engine alone can transport the person.
B. The person can be transported without the car's parts interacting.
C. The individual parts (engine, wheels, chassis) cannot transport a person, but the assembled system
can.
D. The car's ability to transport is a property of its tires.
, Correct Answer: C
Rationale: This is the definition of an emergent property. The whole (the car) has a function that
none of its parts can perform on their own.
9. Which term describes a feedback loop that amplifies change?
A. Balancing Feedback
B. Reinforcing Feedback
C. Dampening Feedback
D. Negative Feedback
Correct Answer: B
Rationale: Reinforcing feedback (also called positive feedback) is self-reinforcing. It generates
growth or decline in the same direction, like a snowball effect. Balancing feedback opposes change and
works towards a goal or equilibrium.
10. A thermostat maintaining a room's temperature is an example of which type of feedback?
A. Reinforcing Feedback
B. Positive Feedback
C. Balancing Feedback
D. Runaway Feedback
Correct Answer: C
Rationale: A thermostat works to balance the temperature. If it's too cold, it turns on the heat; if it's
too hot, it turns it off. It is a classic example of a balancing (or negative) feedback loop, as it counteracts
deviations from the desired set point.
11. "Interest on a bank account" is an example of which type of feedback loop?
A. Balancing Feedback
B. Negative Feedback
C. Reinforcing Feedback
D. Stabilizing Feedback
