Question

Determine whether the stated conclusion is valid based on the given information. Explain your reasoning.

Given: If a lawyer passes the bar exam, then he or she can practice law. Candice passed the bar exam.
Conclusion: Candice can practice law.
Select one:


a. invalid; There is not enough information given to form a conclusion.

b. valid; Law of Syllogism

c. invalid; Candice may have passed the bar exam, but chose not to practice law.

d. valid; Law of Detachment

Answer 1

The answer is D. The law of detachment states that
"If P than Q. P."
In this case passing the bar exam is P and getting to practice law is Q. So if we know that Candice is allowed to practice law if she passes the bar exam and that she did pass the exam. The conclusion that Candice can now practice law is valid.
