Question 3

The combination you will not find in a sound argument is:
A) True premises and a true conclusion
B) True premises and valid reasoning
C) False premises or invalid reasoning
D) All of the above

Accepted Answer

A sound argument is defined by having true premises and valid reasoning that leads to a true conclusion. Therefore, the combination of false premises or invalid reasoning does not apply to a sound argument.

Question 4

The combination you will not find in a sound argument is:
A) True premises and a true conclusion
B) True premises and valid reasoning
C) True premises and invalid reasoning
D) All of the above

Accepted Answer

A sound argument requires both true premises and valid reasoning. If the reasoning is invalid, the argument cannot be sound, even if the premises are true.

Question 5

The text divides all arguments into these very general categories:
A) Nomatic, dimatic, and pumatic
B) Inductive and deductive
C) True and false
D) Sentential and paragraphical

Accepted Answer

Arguments are generally categorized into inductive and deductive based on their reasoning structure. Inductive arguments infer generalizations from specific instances, while deductive arguments derive specific conclusions from general principles.

Question 6

In a valid argument:
A) If the premises are all false, the conclusion must be false.
B) If the premises are all true, then the conclusion cannot be false.
C) If the premises are all false, then the conclusion is likely.
D) The premises must be true.

Accepted Answer

In a valid argument, if all the premises are true, then the conclusion logically cannot be false. This is the definition of a valid argument: the logical structure ensures the truth of the conclusion given the truth of the premises.

Question 7

In a deductive argument:
A) If the premises all are true, then the argument must be valid.
B) If the premises all are false, then the argument must be invalid.
C) If the premises are all true, then the argument is called a "true" argument.
D) None of the above.

Accepted Answer

A deductive argument's validity is determined by its structure, not the truth value of its premises. An argument can be valid if its premises logically lead to its conclusion, regardless of whether those premises are true or false. Therefore, options A, B, and C are incorrect because they misrepresent the nature of deductive arguments and their evaluation.

Question 8

Assume each of the following is a deductive argument. In each case, is the argument valid or invalid? (V or I)
