Premise - ANS-A fact, proposition or statement from which a conclusion is made
Conclusion - ANS-A statement or judgment that follows from one or more reasons.
Conditional Reasoning - ANS-A conditional statement is, in its most easily recognized
form, an "if...then..." statement. The following is, for example, a conditional statement.
Conditional statements are also described in terms of sufficient and necessary
conditions.
Sufficient - ANS-An event or circumstance whose occurrence indicates that a necessary
condition must also occur.
Necessary - ANS-An event or circumstance whose occurrence is required in order for a
sufficient condition to occur.
Explain Sufficient Necessary - ANS-If a sufficient condition occurs, you automatically
know that the necessary condition also occurs. If a necessary condition occurs, then it
is possible that the sufficient condition will occur, but not certain.
Example of Sufficient Necessary - ANS-Banging my shin on the table is all that is
needed for me to scream in pain (i.e. it is sufficient), so banging my shin is considered
the sufficient condition. I cannot bang my shin on the table without screaming in pain
, (screaming necessarily follows the banging of my shin), so screaming in pain is the
necessary condition. You should be fine if you can simply remember that the
antecedent (the phrase following the "if") is the sufficient condition for the consequent
(the phrase following the "then") and the consequent is the necessary condition for the
antecedent.
Contra-positive - ANS-a conditional statement derived from another by negating and
interchanging antecedent and consequent
