conclusions that are well-supported and logically sound. It is not about winning
debates or memorizing information.

true or false. Claims are the building blocks of arguments and are subject to critical
scrutiny through evidence and reasoning.

B. The confidence with which it is delivered
C. The degree to which premises logically support the conclusion
D. The number of sources cited
E. The emotional appeal it makes to the audience
Correct Answer: C. The degree to which premises logically support the
conclusion
EXPERT RATIONALE: Argument strength is determined by how well the
premises logically lead to and support the conclusion. Neither length, confidence,
,source count, nor emotional appeal determines the logical strength of an
argument.

to support a conclusion. "All humans are mortal" is a factual claim used as support
in a syllogism. Phrases like "therefore," "in conclusion," and "it follows that" signal
conclusions, not premises.
5. What is a conclusion in the context of an argument?
A. The first statement made in a debate
B. A piece of evidence used to support a claim
C. The statement that the premises are intended to support
D. A question that needs further investigation
E. A definition of key terms used in the argument
Correct Answer: C. The statement that the premises are intended to support

trying to establish. Premises are the reasons given in support of the conclusion.

what follows is the conclusion being drawn from preceding premises. "Because,"
"since," "given that," and "assuming that" typically introduce premises.
7. Which of the following is a premise indicator?
A. Thus
B. Hence
C. Consequently
D. Because
E. So
Correct Answer: D. Because
EXPERT RATIONALE: "Because" introduces a reason or premise supporting a
conclusion. Words like "thus," "hence," "consequently," and "so" are conclusion
indicators, signaling what is being concluded from the given reasons.
