Introduction
,This comprehensive objective assessment is designed to evaluate foundational skills and knowledge in critical
thinking, reason, and evidence for the WGU D265 course. The exam covers essential competencies including
identifying and evaluating arguments, recognizing logical fallacies and cognitive biases, applying scientific

world scenarios, candidates demonstrate the ability to analyze information, construct sound arguments, and apply
critical thinking in academic and professional contexts. This examination serves as a critical tool for assessing
readiness for the course, emphasizing analytical reasoning, ethical judgment, and effective decision-making in a
complex information environment.
SECTION ONE: QUESTIONS 1–100
1. Which of the following best defines a proposition in logic?
A. A sentence that asks a question
B. A declarative sentence that is either true or false
C. A sentence that expresses a command
D. A sentence that expresses an opinion
🟢B
🔴 RATIONALE: A proposition is a declarative sentence that makes a claim and has a truth value—it is either
true or false. Questions and commands do not have truth values and are not propositions.
,2. An argument consists of:
A. A single statement
B. A set of premises that support a conclusion
C. A conclusion without supporting reasons
D. A fact and an opinion
🟢B
🔴 RATIONALE: An argument is a set of statements (premises) that are intended to support or justify a
conclusion. A single statement or a conclusion without support does not constitute an argument.
3. "All humans are mortal. Socrates is a human. Therefore, Socrates is mortal." This argument is an example of:
A. Inductive reasoning
B. Deductive reasoning
C. Analogical reasoning
D. Abductive reasoning
🟢B
🔴 RATIONALE: This is a classic example of deductive reasoning, where the conclusion follows necessarily from
the premises. If the premises are true, the conclusion must be true.
, 4. Which of the following is an example of a cognitive bias?
A. Confirmation bias
B. Deductive reasoning
C. Inductive reasoning
D. Critical thinking
🟢A
🔴 RATIONALE: Confirmation bias is the tendency to favor information that confirms pre-existing beliefs, while
disregarding evidence that contradicts them. It is a common cognitive bias.
5. A person says, "I don't believe in climate change because my uncle is a scientist and he says it's not real." This
is an example of:
A. Appeal to authority
B. Ad hominem
C. Straw man fallacy
D. False dichotomy
🟢A
🔴 RATIONALE: This is an appeal to authority fallacy because the person relies on a single authority figure's
opinion rather than evaluating the scientific evidence on climate change.
