(1) Scott said that if the light was on when we came by, we could be assured that he was home, and (2) the light isn’t on. Therefore, (3) Scott must not be home.
Which of (a), (b), (c) or (d) is correct in relation to the above argument?
(a) (2) and (3) are the premises
(b) The conclusion is (2)
(c) (1) and (2) are the premises
(d) (1) and (3) are the premises
@titaween,
I'm confused by your use of the word premise.
In your example, (1) is a basic premise (a rule, or axiom) , (2) is a condition (you may wish to call it a premise for the sake of this argument), while (3) is an (incorrect) conclusion.
@titaween,
(c) is correct.. The word 'therefore' announces the conclusion.
(And the argument is invalid ).
Stumble It!
