Domain 1: Foundations of Critical Thinking (12 Questions)
Q1: Which of the following best defines critical thinking as understood in the WGU EKO1
D256 curriculum?
A. The ability to memorize large amounts of information quickly and accurately
B. The systematic evaluation and formulation of beliefs by rational standards
[CORRECT]
C. The process of finding evidence that confirms one's existing beliefs
D. The skill of persuading others through emotional appeals and rhetorical techniques
Correct Answer: B
Rationale: Critical thinking is fundamentally the systematic evaluation and formulation
of beliefs by rational standards, involving analysis, assessment, and reconstruction of
thought. Option A confuses critical thinking with rote memorization. Option C describes
confirmation bias, which is antithetical to critical thinking. Option D describes rhetoric or
persuasion, which may or may not involve critical thinking depending on whether
rational standards are applied.
Q2: In the context of argument analysis, what is the primary function of a premise?
A. To provide the conclusion that the argument is trying to establish
B. To offer reasons or evidence supporting the conclusion [CORRECT]
C. To restate the conclusion in different words
D. To attack the character of anyone who disagrees
Correct Answer: B
Rationale: A premise is a statement that provides support, reasons, or evidence for the
conclusion. It answers the question "Why should I accept the conclusion?" Option A
,confuses premises with conclusions. Option C describes circular reasoning. Option D
describes the ad hominem fallacy, which is irrelevant to the structural role of premises.
Q3: Consider the following statement: "All humans are mortal. Socrates is human.
Therefore, Socrates is mortal." This argument demonstrates:
A. Inductive reasoning based on probability
B. Deductive reasoning where the conclusion necessarily follows from the premises
[CORRECT]
C. Abductive reasoning to the best explanation
D. Analogical reasoning based on similarity
Correct Answer: B
Rationale: This is a classic example of deductive reasoning (specifically a categorical
syllogism) where if the premises are true, the conclusion must be true. The conclusion
necessarily follows with 100% certainty. Option A is incorrect because inductive
reasoning deals with probability and likelihood, not necessity. Option C (abductive
reasoning) involves inference to the best explanation. Option D (analogical reasoning)
involves comparing similarities between cases.
Q4: A deductive argument is considered valid when:
A. All of its premises are actually true in the real world
B. Its conclusion follows necessarily from its premises [CORRECT]
C. It persuades the majority of people who hear it
D. It contains at least three premises
Correct Answer: B
Rationale: Validity in deductive logic refers to the logical structure of the
argument—specifically, whether the conclusion necessarily follows from the premises,
assuming the premises are true. Validity is about logical form, not actual truth. Option A
describes soundness (valid + true premises). Option C confuses validity with
persuasiveness or rhetorical effectiveness. Option D is arbitrary; arguments can be valid
with any number of premises.
Q5: An argument is sound if and only if:
A. It is valid and all its premises are actually true [CORRECT]
B. It is persuasive to a reasonable audience
, C. It contains no emotional language
D. It is invalid but has true premises
Correct Answer: A
Rationale: Soundness requires both validity (proper logical form) and actually true
premises. This is the highest standard for deductive arguments. Option B confuses
soundness with rhetorical effectiveness. Option C is irrelevant to logical soundness.
Option D describes an invalid argument with true premises, which is unsound because
validity is required for soundness.
Q6: Inductive strength refers to:
A. The degree to which the premises make the conclusion probable or likely [CORRECT]
B. The necessity with which the conclusion follows from the premises
C. The emotional impact of the argument on the audience
D. The number of premises included in the argument
Correct Answer: A
Rationale: Inductive strength measures how probable the conclusion is given the
premises. Unlike deductive validity, inductive arguments do not guarantee their
conclusions; they support them to varying degrees. Option B describes deductive
validity. Option C confuses logical strength with emotional appeal. Option D is irrelevant;
more premises do not necessarily mean greater inductive strength.
Q7: An argument is cogent when:
A. It is inductively strong and all premises are actually true [CORRECT]
B. It is deductively valid with false premises
C. It relies solely on statistical evidence
D. It convinces at least 50% of listeners
Correct Answer: A
Rationale: Cogency is the inductive equivalent of soundness: an argument must be
inductively strong (premises make conclusion probable) AND have actually true
premises. Option B describes an unsound deductive argument. Option C is too narrow;
cogent arguments can use various types of evidence. Option D confuses cogency with
popularity.
