Preserve intended meaning by avoiding ambiguity and illogical shifts.
Choose wording that keeps the sentence's intended meaning unchanged.
Core Idea
A grammatically correct sentence can still be wrong if it says something the writer didn't mean. The SAT tests whether the answer choice preserves the intended meaning — no accidental ambiguity, no logic-breaking shifts in subject, voice, or perspective.
Understanding
Some SAT questions aren't about finding a grammar error — they're about finding the answer that says what the passage means to say. A sentence can be grammatically flawless and still be wrong because it creates ambiguity or shifts the meaning in an unintended direction.
Three common traps:
Ambiguous pronoun reference. When a pronoun could refer to more than one noun, the sentence's meaning splits:
The architect showed the client the revised blueprint, and he was pleased with the changes.
Who was pleased? The architect or the client? The correct answer will make this unambiguous.
Illogical shifts in subject or voice. A sentence that switches from active to passive (or changes its grammatical subject mid-stream) can lose its intended meaning:
The researchers conducted the study, and errors were found in the data.
Who found the errors? The passive voice hides the agent. If the passage means to say the researchers found errors, the sentence needs to say so.
Unintended scope changes. Moving a word or phrase can accidentally change what the sentence claims:
The medication only reduces symptoms (it doesn't cure them) vs. The medication reduces only symptoms (it doesn't reduce anything else).
The fix: always ask "does this answer choice say exactly what the passage intends?"
Step by Step
- Read the passage for intended meaning before looking at answer choices.
- For each answer choice, ask: does this create any ambiguity about who did what, or what happened?
- Check for unintended shifts — does the subject change? Does the voice switch from active to passive without reason?
- Watch for scope changes — does moving a modifier accidentally change the sentence's claim?
- Pick the choice that communicates the passage's intended meaning with zero ambiguity.
Misconceptions
- Thinking grammar correctness guarantees meaning correctness. A sentence can be perfectly grammatical and still say the wrong thing.
- Ignoring passive voice shifts. When a sentence switches from active to passive, the agent can disappear — and with it, the intended meaning.
- Assuming ambiguity is always obvious. Sometimes two readings of a sentence are both plausible, and only the passage context reveals which one the author intended.
