Main Idea vs. Topic vs. Theme

The topic is the broad subject (a word or phrase), while the main idea is the author's specific claim about it — always a full sentence. A theme is a universal truth drawn from narrative, distinct from the passage-specific main idea.

Key Points

  • •
    Apply the 'So What?' test: if you can say it in two words, it's the topic; if it needs a sentence, it's the main idea
  • •
    The main idea acts as an umbrella covering all supporting details — too narrow means you picked a detail, too broad means you picked the topic
  • •
    Check the last sentence of the first paragraph and the first sentence of the conclusion for the thesis statement
  • •
    Implicit main ideas require synthesizing what ALL details collectively point toward
  • •
    Theme = abstract universal lesson ('Power corrupts'); Main idea = specific claim tied to the passage's content

Author's Purpose (PIE)

Every text's primary purpose is to Persuade, Inform, or Entertain. Identifying the dominant purpose — even in hybrid texts — is key to understanding what the author wants the reader to do, know, or feel.

Key Points

  • •
    Persuade: look for 'should', 'must', 'essential', calls to action, and rhetorical questions
  • •
    Inform: look for 'studies show', 'according to', neutral language, data, and citations
  • •
    Entertain: look for vivid imagery, dialogue, humor, suspense, and narrative techniques
  • •
    Most passages serve multiple purposes — identify the PRIMARY one the author would sacrifice last
  • •
    A 'best title' question is a main idea question in disguise — the correct title captures the claim, not just the topic

Scanning and Detail Retrieval

Detail questions require locating explicit information using targeted scanning — reading the question first, locking onto anchor words, then sweeping the passage for matches or paraphrases.

Key Points

  • •
    Anchor words are unique identifiers (names, dates, numbers, technical terms) unlikely to be paraphrased
  • •
    Correct answers are often paraphrases — 'yearly precipitation declined' restates 'annual rainfall decreased'
  • •
    The 'According to the Passage' rule means text evidence overrides outside knowledge, even common sense
  • •
    For NOT/EXCEPT questions, verify all four options against the text — the one missing or contradicted is correct
  • •
    Narrative order in the passage may differ from actual chronological order — read for logical sequence, not paragraph position

Qualifier Traps and Scope Matching

Qualifiers ('most', 'nearly', 'some', 'often') limit the scope of a claim, and misreading or dropping them is the single most common source of wrong answers in both detail and inference questions.

Key Points

  • •
    Absolute qualifiers ('always', 'never', 'all', 'none') are red flags — passages rarely make universal claims
  • •
    'Nearly 70%' ≠ '70%' ≠ 'over 70%' — match the qualifier's direction and precision exactly
  • •
    Temporal qualifiers ('before', 'during', 'after') change which detail is correct — a single preposition matters
  • •
    The correct answer's scope must match the passage: 'some researchers believe' cannot become 'all scientists agree'
  • •
    Stronger qualifiers require stronger evidence — rank from 'all/never' (strongest) to 'some/may' (weakest)

Inference and the Scope Rule

A valid inference merges explicit textual evidence with logical reasoning to derive unstated meaning — it must always remain within the passage's scope and never rely on outside knowledge.

Key Points

  • •
    Every inference must be traceable to specific words or patterns in the text — no evidence means it's a guess, not an inference
  • •
    Strong inferences have multiple converging clues; weak ones rest on a single ambiguous detail
  • •
    Conclusions synthesize multiple localized inferences into a single global judgment about the passage as a whole
  • •
    Predictions must follow established patterns or causal chains — a sudden reversal requires new evidence
  • •
    Eliminate options with absolute qualifiers, out-of-scope claims, or logical reversals of what the passage implies

Drawing Conclusions vs. Summarizing

A summary restates what happened; a conclusion explains what it means or why it matters. Conclusion questions require synthesizing evidence across the entire passage into a final judgment.

Key Points

  • •
    Conclusion triggers: 'Which can be concluded...', 'The passage as a whole suggests...', 'The author's primary purpose...'
  • •
    Inference triggers target specific parts: 'The passage suggests...', 'The author implies...'
  • •
    A conclusion must follow as a logical consequence from the premises the author provides
  • •
    When evidence conflicts, weigh the preponderance — don't anchor to a single outlier detail

Vocabulary in Context (IDEAS Framework)

The IDEAS framework categorizes five context clue types — Inference, Definition, Example, Antonym, Synonym — each triggered by specific signal words that help decode unfamiliar vocabulary.

Key Points

  • •
    Definition signals: 'which means', 'that is', dashes, parentheses setting off a restatement
  • •
    Antonym signals: 'however', 'despite', 'unlike', 'rather than' — the opposite meaning follows
  • •
    Example signals: 'such as', 'including', 'for instance' — listed members narrow down the category
  • •
    Synonym signals: 'or', 'also known as', commas around an appositive
  • •
    When no signal exists, infer from overall sentence logic — what role must this word play for the sentence to make sense?

Secondary Meanings and Parts of Speech

Polysemous words have multiple meanings, and test questions almost always require the secondary or context-specific meaning — identifying the word's part of speech in the sentence eliminates entire categories of wrong answers.

Key Points

  • •
    If all options include both a common and uncommon definition, the secondary meaning is almost always correct
  • •
    'Appropriate' as a verb means 'to allocate/seize', not 'suitable' — check if the word follows 'to' or a subject
  • •
    Break unfamiliar words into prefix + root + suffix: 'in-' (not) + 'cred' (believe) + '-ulous' (tending to) = disbelieving
  • •
    Use the substitution strategy: blank the word, predict a simple replacement, check tone alignment, then match to options
  • •
    The answer's connotation must match the passage tone — a positive context demands a positive-connotation word

Tone: Diction, Syntax, and Attitude Markers

Tone is the author's attitude toward the subject, revealed through word choice (diction), sentence structure (syntax), and attitude markers like adverbs ('unfortunately', 'obviously') that inject judgment into seemingly neutral facts.

Key Points

  • •
    Tone ≠ Mood: tone is the author's attitude; mood is the feeling the reader experiences
  • •
    Short, punchy sentences signal urgency or anger; long, flowing ones suggest reflection or formality
  • •
    Attitude markers: 'merely'/'just' minimize importance; 'crucial'/'vital' amplify it — both reveal bias
  • •
    Euphemism ('downsizing' for 'firing') and passive voice ('mistakes were made') hide the actor and soften harsh realities
  • •
    Use the three-question test: Is the author FOR or AGAINST? How STRONGLY? Are they being DIRECT or INDIRECT (ironic)?

Rhetorical Appeals and Tone Shifts

Persuasive writing layers three classical appeals — ethos (credibility), pathos (emotion), logos (logic) — and skilled authors shift tone within a passage using pivot words that signal their true position.

Key Points

  • •
    Ethos: 'As a doctor...', citing reputable sources — establishes trust and authority
  • •
    Pathos: vivid imagery, personal stories, emotionally charged words — evokes feelings to motivate action
  • •
    Logos: statistics, cause-and-effect reasoning, 'therefore' — appeals to reason through evidence
  • •
    Pivot words ('however', 'but', 'yet', 'nevertheless') mark tone shifts — the tone AFTER the pivot is usually the author's true position
  • •
    Concession-rebuttal pattern: 'It is true that... However...' — the rebuttal reveals the real stance
