Dialogue in the stimulus. Speakers will make arguments and they will disagree about one particular aspect of their arguments.
28
Point at issue question strategy
Decision tree - did author A have an opinion about this "yes/no" did author B have an opinion about this "yes/no" - what was that opinion.
29
Method of Argument | Argument by Analogy

39
Parallel Reasoning Questions
Identify two different arguments (one in stimulus one in answer choices) that use the same pattern to reach a similar conclusion
40
"most parallel to" "most similar to" "most like"
Parallel reasoning question stems
41
Parallel reasoning questions require you to find the same kind of ____ and ____ in the stimulus and answer
Evidence and conclusion
42
Tactic for parallel reasoning questions:
- identify and compare conclusion type in stimulus and answers, then if needed.... - Compare Conclusion +/- - Compare Level of certainty of conclusion (may, will, must) - Compare type of evidence used
43
Assumption family questions require that you determine the ___
implicit assumption (aka the unstated premise)
44
Assumption =
the unstated premise that logically connects the evidence to the conclusion
45
Mismatched Concept (assumption family questions)
The author moves from a discussion of particular terms and concepts in the evidence to a conclusion that introduces a new seemingly unrelated term or concept
46
Overlooked Possibilities (assumption family questions)
The author uses relevant evidence to jump to a conclusion that is too extreme, without considering potential objections or alternatives to that conclusion
47
Assumption questions - find the ___ in the argument
gap
48
Mismatched concepts - assuming one thing is equivalent to another ex:
I like games because I am serious | serious = liking games
49
Mismatched concepts - things are incompatible or mutually exclusive ex:
I don't like games because I am serious | assume can't have both
50
Mismatched concepts - sufficient, necessary - need evidence for conclusion ex:
I don't like games because I am not serious | Not X because not Y
51
Formal logic in mismatched concept, what is the most common format?
Evidence: if A -> B Conclusion: if A ->C Assumption: if B ->C
52
How to use overlooked possibilities - Evidence and Conclusion use same topic but the conclusion drawn____
goes too extreme based on what your given. I.e. this MUST be the only answer, fails to consider alternatives.
53
Presupposes =
Assumes
54
What to look for in Sufficient Assumption questions
look for answer that, if added to the evidence, guarantees the conclusion is true
55
What to look for in Necessary Assumption questions
look for assumption that is necessary for the conclusion to make logical sense
56
`Necessary Assumption questions with overlooked possibilities (not mismatched concepts) the right answer might come from ____
ruling out at least 1 overlooked possibility.
57
Denial test for Nec. Assumption questions____
negate answer choice and "add" to evidence. If the conclusion doesn't work now then that's your right answer. I.e. this thing (not negated) is required.
58
