PT 66 4: 17

Test: PT 66
Question: Section 4: Question 17
Section: Logical Reasoning
First words: "Although Pluto has an atmosphere..."
Type: Definition
Answer: E
Your Answer: Enter

Strategy: As you read the stimulus, note any terms or concepts introduced in the conclusion. The argument will treat some part of the evidence as though it is the same or similar to that new term or concept. Pre-phrase a statement that links the terms in the evidence and conclusion that the stimulus treats as though they are the same.

Explanation:

BridgeAlthough
ConclusionPluto is not a true planet.
Type of Conclusiondefinition
Prephrase of pieces that need to be linkednot a true planet, formed in orbit

  1. This is wrong because the argument does not mention whether Pluto is or was ever a moon, so whether it can simultaneously be a moon and a planet does not have any implications for whether it is a planet.
  2. Keywords that allow elimination: moon

  3. This is wrong because while this is necessary for the conclusion to be true, it does not complete the argument, since it does not show why this particular celestial body with an atmosphere is not a true planet.
  4. Keywords that allow elimination: not all

  5. This is wrong because what would have happened to Pluto if it had not left Neptune's orbit is irrelevant to its definition now.
  6. Keywords that allow elimination: if Pluto had not

  7. This is wrong because just because size is not relevant does not imply that a given large celestial body is NOT a true planet. The argument needs something more.
  8. Keywords that allow elimination: size

  9. This is correct because it would mean that because Pluto formed in orbit around Neptune (evidence 2) and thus did not form in orbit around the sun, it could not be a true planet.
