Question

Either Bill Clinton or George W. Bush was president when the World Trade Center towers were destroyed. But Bush was not president at that time. Therefore, Bill Clinton was president when those buildings were destroyed. a. Inductive, weak, uncogent. b. Deductive, valid, sound. c. Deductive, invalid, unsound. d. Deductive, valid, unsound. e. Inductive, strong, cogent.

Answer 1

d). deductive, valid, unsound

Step-by-step explanation:

A deductive argument refers to an argument which is
`\text{intended by the arguer}` that is to be
`\text{deductively valid}`, i.e., to provide guarantee of the truth of the conclusion provided.

When all the premises of an argument are true, then it is called a valid argument.

When an argument is either valid or invalid having at least one false premises, then it is unsound.

Thus in the context, the argument is deductive, valid and an unsound argument.

Hence the correct option is (d).
