32 cards. Read the term and the definition here. The deck at the top of this page is optional.

Main idea
The central claim that the entire passage is organized to support; a correct answer must account for all paragraphs, not only the opening one.
Primary purpose
The author's overall aim, expressed as a verb plus object such as 'explain a phenomenon' or 'challenge a theory,' rather than a summary of content.
Contrast signal words
Words like 'however,' 'but,' and 'yet' that mark a shift in direction; the author's own view often appears right after such a signal.
Detail question rule
Answer only from information explicitly stated in the passage; a choice that is factually true but absent from the text is incorrect.
Valid inference
A statement that must be true given the passage; answers using 'could' or 'possibly' fail when the question demands certainty.
Author versus subject
The author may report others' views without endorsing them; viewpoint questions require separating the author's stance from described researchers' claims.
Overstated answer choice
A tempting wrong option that uses absolutes like 'all' or 'never,' narrows the scope improperly, or reverses a stated causal relationship.
Tone from modifiers
Attitude is inferred from evaluative adjectives and adverbs such as 'merely' or 'remarkably,' not from the topic alone.
Conclusion
The claim an argument is trying to establish; it is usually the statement that weaken, strengthen, and evaluate questions target.
Premise
Evidence or a stated reason offered in support of the conclusion; premises are accepted as given and are not what the question asks you to attack.
Necessary assumption
An unstated premise required for the conclusion to follow; negating it makes the argument collapse, which confirms it is necessary.
Weaken answer
Attacks the link between premise and conclusion via an alternative cause, reversed causation, or unrepresentative sample; it need not disprove the conclusion.
Strengthen answer
Supplies a missing link or rules out an alternative explanation, increasing support for the conclusion without needing to make it certain.
Causal argument flaws
A claim that X causes Y is weakened if Y causes X, a third factor causes both, or the observed correlation is coincidental.
Sample flaw
An argument generalizing from a group is weakened if the sample is unrepresentative or too small, and strengthened if it is random and adequate.
Evaluate question test
The correct answer is a question whose two possible replies point in opposite directions for the conclusion, so either reply affects the argument.
Boldface role
In boldface questions, label each bold statement as evidence, intermediate conclusion, or main conclusion, and state its relation to the main conclusion.
Sufficient versus necessary
A sufficient condition guarantees the outcome; a necessary condition is required for it. Confusing the two is a common wrong-answer trap.
Scope shift
A flaw where the conclusion introduces a term or group not covered by the premises, making the reasoning invalid.
True subject
The head noun of the subject, found by stripping prepositional phrases and modifiers; the verb must agree with it, not the nearest noun.
Pronoun antecedent
A pronoun needs exactly one logical antecedent agreeing in number and person; ambiguous 'it' or 'they' references are incorrect.
Dangling modifier
An introductory modifying phrase must describe the subject of the main clause that immediately follows it; otherwise the modifier dangles.
Parallelism rule
Items joined by 'and,' 'or,' 'but,' or 'not only...but also' must share grammatical form, such as noun with noun or clause with clause.
Logical comparison
Comparisons must place like with like and supply the missing noun or verb when ellipsis would make the comparison ambiguous.
Fewer versus less
Use 'fewer' with countable nouns and 'less' with uncountable nouns; use 'number of' for countable items and 'amount of' for uncountable.
Past perfect use
Use past perfect only for an action completed before another past action; avoid shifting tense without a time-based reason.
Idiom caution
Fixed constructions like 'ability to' and 'prohibit from' are tested, but unfamiliar idioms are rarely the intended deciding split between choices.
Split and compare
Find the first difference between answer choices, eliminate on a clear grammar rule, then proceed to the next point of difference.
Modifier proximity
A modifier should sit next to the word it describes; moving it changes meaning and often creates the error tested in a choice.
Diction versus grammar
Grammar errors (agreement, parallelism, reference) are decisive; word-choice preferences are weaker and should be used only after grammar splits.
Verb tense sequence
Tenses must reflect the actual order of events; a past action preceding another past action takes past perfect, otherwise simple past.
Countable noun test
If a noun can be counted individually it takes 'fewer' and 'number'; mass nouns take 'less' and 'amount.'
