Logical reasoning question parts Correct Answersstimulus, prompt, and 5 answer
choices
stimulus Correct Answerssubject matter of the logical reasoning question
prompt Correct Answersquestion about the stimulus in the logical reasoning question
Step 1 to Logical Reasoning questions Correct Answersread the question prompt first
do that you are aware of what you're being asked for
Step 2 to Logical Reasoning questions Correct Answersmove on to the stimulus and
read it carefully and deliberately
Step 3 to Logical Reasoning questions Correct AnswersConsider the basic form that the
right answer will have.
Types of Logical Reasoning questions Correct Answersimplication, operation, and
characterization
Implication questions Correct AnswersA question in which you are asked to draw an
inference and everything in the stimulus must be believed to be true
Operation questions Correct AnswersA question that allows answer choices to perform
an operation on the stimulus, each answer choice should be treated as true to see how
it affects the stimulus
Characterization questions Correct AnswersA question in which you read the stimulus
and the. are asked to characterize it in some way
What is the best way to approach a Characterization Logical Reasoning question?
Correct AnswersThe best way to respond is to ask yourself, "what makes this argument
work?"
Proposition Correct Answersthe basic unit of assertion
Sentence Correct Answersone or multiple propositions
argument Correct Answersa set of propositions in which one or more propositions are
intended to provide support for another proposition
premises Correct Answerspropositions upon which an argument is based, they are
stated as facts and are intended to support a conclusion
conclusion Correct Answerspropositions that are supported by premises
premise keywords Correct Answerssince, because, for, as, after all, moreover, in
addition, given that
conclusion keywords Correct Answerstherefore, thus, hence, so, as a result,
consequently, it follows that, it is clear that
assumptions Correct Answersclaims that are not explicitly stated but that must be true
in order for the conclusion to be inferred from the premises
steps to breaking down arguments Correct Answers1. locate the conclusion
2. find the premises
3. identify any assumptions
logical Correct Answersnot concerned with the truth but with implications, inferences,
and validity
Greek symbol for entailment Correct Answers3 dots in a triangle formation
valid argument Correct Answersconclusion is properly inferred from the premises
invalid argument Correct Answersconclusion cannot be properly inferred from the
premises
, absolute statements Correct Answersassert the existence of some fact
conditional statements Correct Answersassert the existence of a hypothetical
relationship between conditions
elements of a conditional statement Correct Answerssufficient condition and necessary
condition; goes from sufficient to necessary
sufficient condition Correct Answerssatisfied condition is enough to guarantee that a
necessary condition will follow
necessary condition Correct Answersrequired for a sufficient condition to be satisfied
valid affirmation Correct Answersthe most basic inferences that can be drawn from a
conditional statement, if a sufficient condition is satisfied then that is always enough to
conclude that the necessary condition follows
contrapositive Correct Answersflipping a conditional statement and negating it. switch
and negate. switch and negate. switch and negate. switch and negate. denying a
necessary conclusion is always enough to conclude that a sufficient condition will not
follow.
contrapositive inferences Correct Answersthe contrapositive is always a valid inference
fallacy of the inverse Correct Answersnegating both conditions without switching them
will result in an invalid inference
Invalid inference Correct Answersdenying a sufficient condition does not necessarily
imply that a necessary condition cannot obtain, the inverse is always an invalid
inference
Sufficiency key words Correct Answersif, when, whenever, all, any, each, every
Necessity key words Correct Answersthen, only, only if, only when, needs, requires,
must
If and only if statements Correct Answersit is both sufficient and necessary, either both
occur or neither
unless, Until, Without, Except Correct Answersstatements that could be easily replaced
with "if not"
no (none) statements Correct Answersthis type of statement posits that there is no
overlap between two conditions, no A's are B's implies that all A's are not B's
transitive property Correct Answerswhen a conditional statement's necessary condition
is identical to the sufficient condition of another conditional statement, always a valid
inference
How many processes are there in the logic games? Correct Answers2
ordering Correct Answerstaking a variable set and lining them up
grouping Correct Answersinstead of lining them up, you have to make teams
What is the most common type of logic game? Correct Answersordering games
Steps for Logic Games Correct Answers1. read the introduction and the rules, decide if
there is any ordering or grouping involved
2. build your setup by identifying all variable sets
3. symbolize the rules
4. double check each rule
5. identify anyone who is not involved in the rules
6. make deductions
7. work out scenarios from the question
8. eliminate, absolute, conditional
