Inference from Text - Verbal Reasoning

1. What is the best inference from: "If the engine overheats, the system shuts down" and "The system shut down"?

   The engine may have overheated, but it is not certain. The conditional statement allows for the antecedent as a possible cause but does not necessitate it due to potential other factors.

2. What is the "cause-and-effect" trap in inference questions?

   It turns correlation or sequence into causation without support. This trap assumes causation from mere association or timing, lacking textual evidence to justify the causal link.

3. What is the "reversal" trap in inference answer choices?

   It flips the direction of a relationship stated in the passage. Reversal traps invert the passage's stated relationships, creating inferences that contradict the original direction of evidence.

4. What is the best inference from: "All the committee members voted for the proposal"?

   No committee member voted against the proposal. The statement 'all voted for' logically implies no opposition, as it encompasses the entire group without exceptions.

5. What is the best rule for choosing between two plausible inference answers?

   Choose the option with stronger, more direct textual support. Stronger textual support ensures the inference is more reliably derived from the passage without introducing unwarranted assumptions.

6. What is the best inference from: "The author cites two studies but notes their small sample sizes"?

   The author treats the studies as suggestive, not definitive. Noting limitations like small samples implies the author regards the evidence as preliminary rather than conclusive.

7. What is the best inference from: "Only certified technicians may access the lab" and "Dana accessed the lab"?

   Dana is a certified technician. The restrictive 'only' combined with the action logically requires the condition to be met for access to occur.

8. What is the key difference between an inference and a paraphrase in GRE reading?

   Inference adds a supported implication; paraphrase restates explicitly stated ideas. Inferences extend the text by drawing implied conclusions, whereas paraphrases merely reword what is directly stated.

9. Which words in an answer choice most often signal an appropriately cautious inference?

   May, might, can, likely, tends to, suggests, some, often. Such qualifiers indicate inferences that appropriately hedge claims to match the tentative or partial support in the passage.

10. What is the key difference between an inference and speculation in GRE reading?

    Inference is text-supported; speculation goes beyond what the text justifies. Inferences remain grounded in textual evidence, while speculation introduces unsupported possibilities beyond the passage.

11. What is the best inference from: "Most residents supported the measure"?

    More than half of the residents supported the measure. The term 'most' denotes a majority, which by definition exceeds 50 percent of the total group.

12. What is the best inference from: "Some of the artifacts were forged"?

    At least one artifact was forged. The quantifier 'some' logically entails at least one instance, directly supported by the statement without additional assumptions.

13. What is a common wrong-answer trap involving scope in inference questions?

    An answer generalizes beyond the passage's limited group, time, or context. Scope traps occur when an answer extends the passage's specific evidence to broader, unsupported contexts or populations.

14. What is the best inference from: "Few applicants met the criteria"?

    Not many applicants met the criteria. The term 'few' implies a small number, which logically supports the inference of not a large quantity without contradiction.

15. What is the best inference from: "Although the drug is effective, it has serious side effects"?

    The author views the drug as beneficial but risky. The concessive structure 'although' balances positive efficacy with negative risks, implying a nuanced authorial perspective.

16. What does it mean for an inference answer to be "too strong" on the GRE?

    It uses absolute language not warranted by the passage's evidence. An inference is too strong when it employs definitive terms that exceed the qualified or limited evidence provided in the passage.

17. Which words in an answer choice most often signal an overly strong inference?

    Always, never, proves, completely, impossible, must, all, none. These absolute terms often indicate an inference that oversteps the passage's evidence by claiming certainty without sufficient support.

18. What is the best definition of a valid inference from a text on GRE Verbal?

    A conclusion strongly supported by stated facts, without new assumptions. Valid inferences in GRE Verbal must derive directly from the text's explicit information, ensuring logical support without external assumptions.

19. What is the best inference from: "Unlike previous models, this device is repairable"?

    Previous models were not repairable. The contrast 'unlike' directly implies that prior versions lacked the quality present in the current one.

20. What is the best method for verifying an inference answer choice quickly?

    Locate the supporting lines and confirm no extra claim is added. This method ensures the choice is directly supported by the text without introducing unstated assumptions or extrapolations.

21. What is the "percent vs number" trap in inference answer choices?

    It confuses rate changes with absolute quantity changes. This trap misinterprets proportional changes as shifts in total amounts, leading to unsupported inferences about quantities.

22. What is the best inference from: "The researcher did not find evidence of fraud"?

    Fraud was not proven by the researcher's investigation. Lack of evidence discovery implies absence of proof, but does not confirm the non-existence of the phenomenon itself.

23. Which answer choice type is most often correct for an inference question: extreme or cautious?

    Cautious, qualified claims that match the passage's support. Inference questions favor cautious choices because they align with the passage's evidence without overreaching into unsupported extremes.

24. What is the best inference from: "The policy was intended to reduce pollution"?

    Reducing pollution was a goal of the policy. Stating intention directly implies that the specified outcome was a deliberate objective of the policy's design.
