LSAT - Logical Reasoning
Premise correct answersA fact, proposition or statement from which a conclusion is made
Conclusion correct answersA statement or judgment that follows from one or more reasons.
Conditional Reasoning correct answersA 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 correct answersAn event or circumstance whose occurrence indicates that a necessary
condition must also occur.
Necessary correct answersAn event or circumstance whose occurrence is required in order for a
sufficient condition to occur.
Explain Sufficient Necessary correct answersIf 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 correct answersBanging 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 correct answersa conditional statement derived from another by negating and
interchanging antecedent and consequent
