Draw Logical Conclusions - International Brotherhood of Electrical Workers Exam IBEW
- Which conclusion is best supported: The passage states two events happened on the same day.
- They occurred on the same day, not necessarily that one caused the other. Co-occurrence on the same day supports simultaneity but does not establish causation without further evidence.
- What is the best rule for handling outside knowledge when drawing conclusions from a passage?
- Do not add outside facts; rely only on passage evidence. Conclusions must stem solely from the passage to avoid bias or irrelevant influences from external information.
- Identify the logical flaw: concluding "A caused B" only because A happened before B.
- Post hoc (false cause) fallacy. This fallacy assumes causation from mere temporal precedence without evidence of a causal link.
- Which conclusion is valid: All electricians in the program passed; Jordan is in the program.
- No valid conclusion that Jordan passed. The premises do not specify Jordan's role as an electrician, preventing a deductive conclusion about passing.
- Which transition word most strongly signals an example is being introduced?
- For example. 'For example' precedes specific instances that illustrate or clarify a general concept mentioned earlier.
- Which conclusion is best supported: "The system is not reliable" appears in the passage.
- The system sometimes fails or cannot be consistently trusted. 'Not reliable' implies inconsistency or occasional failure, as supported by the passage's explicit statement.
- What is the best definition of an assumption in passage-based reasoning?
- An unstated belief required for an argument to work. Assumptions are implicit ideas that must be true for the passage's argument to hold logically.
- What is the best rule for choosing a conclusion when two options both seem plausible?
- Choose the option most directly supported by the text. Prioritize conclusions with the strongest textual backing to ensure they are logically derived from the passage.
- Which conclusion is valid: If the breaker trips, the circuit opens; the breaker tripped.
- The circuit opened. This follows modus ponens logic: affirming the antecedent (breaker tripped) entails the consequent (circuit opened).
- Which conclusion is valid: If the breaker trips, the circuit opens; the circuit opened.
- No valid conclusion that the breaker tripped. Affirming the consequent is invalid; other causes could open the circuit without the breaker tripping.
- Which conclusion is best supported: "No tools were missing" appears in the passage.
- All tools were present. Stating 'no tools were missing' logically entails that every tool was accounted for and present.
- Identify the stronger evidence type for a conclusion: one anecdote or repeated measurements.
- Repeated measurements. Repeated measurements offer reliable, empirical data, unlike a single anecdote which is subjective and unrepresentative.
- Which conclusion is best supported: The report says noise decreased after maintenance.
- Maintenance likely contributed to reduced noise. Temporal sequence after maintenance suggests a probable causal link, though not definitive, based on the report's evidence.
- What is the difference between an inference and a guess when reading a passage?
- An inference is evidence-based; a guess lacks textual support. Inferences are drawn from textual evidence and logical reasoning, whereas guesses are speculative without basis in the passage's content.
- Which transition word most strongly signals contrast between two ideas?
- However. 'However' indicates opposition or qualification to a prior statement, highlighting differences between ideas.
- Which conclusion is best supported: "Most apprentices arrived early" appears in the passage.
- More than half arrived early. 'Most' denotes a majority, meaning over 50 percent, as directly implied by the passage's wording.
- Which phrase best signals a cause-and-effect relationship in a passage?
- Because. The word 'because' directly links a cause to its effect by explaining the reason behind an occurrence in the text.
- Which phrase best signals a conclusion or result in a passage?
- Therefore. 'Therefore' introduces a logical outcome or summation derived from preceding information in the passage.
- What is the best definition of an implied idea in a passage?
- A meaning suggested by the text but not directly stated. Implied ideas are suggested through context, wording, or structure without being explicitly expressed in the text.
- What is the best definition of a supporting detail in a passage?
- A specific fact or example that backs up the main idea. Supporting details provide evidence, such as facts or examples, that strengthen and validate the central claim.
- What is the best definition of a logical conclusion drawn from a passage?
- An inference supported by stated facts and valid reasoning. Logical conclusions rely on explicit facts from the passage combined with sound deductive or inductive reasoning to form supported inferences.
- Which conclusion is best supported: "Some tools were missing" appears in the passage.
- At least one tool was missing. The word 'some' logically implies a quantity of at least one, directly supported by the passage's statement.
- Which conclusion is best supported: The passage uses words like "always" and "never" without data.
- The claim is likely overstated. Absolute language without supporting evidence indicates exaggeration or unsubstantiated claims in the passage.
- What is the best definition of a main idea in a short passage?
- The central point that the details support. The main idea represents the primary message or thesis that the passage's details collectively reinforce.
- Which conclusion is best supported: The author lists three benefits and no drawbacks of a policy.
- The author views the policy favorably. Presenting only positive aspects without negatives implies the author's positive stance toward the policy.
