Difficulty: EasyParallel Quantifier Logic

All botanists possess a deep understanding of plant biology. Some participants at the current conference are botanists. Therefore, some participants at the current conference possess a deep understanding of plant biology.

Which of the following arguments is most similar in its logical structure to the argument above?

  1. All experienced pilots undergo rigorous training. Some members of the local aviation club are experienced pilots. Therefore, some members of the local aviation club undergo rigorous training.Answer
  2. B
    Most experienced pilots undergo rigorous training. Some members of the local aviation club are experienced pilots. Therefore, some members of the local aviation club undergo rigorous training.
  3. C
    All experienced pilots undergo rigorous training. Some members of the local aviation club are experienced pilots. Therefore, all members of the local aviation club undergo rigorous training.
  4. D
    All experienced pilots undergo rigorous training. Some members of the local aviation club undergo rigorous training. Therefore, some members of the local aviation club are experienced pilots.
  5. E
    All botanists study plant genetics. Some scientists who study plant genetics are biologists. Therefore, some botanists are biologists.

Answer

The argument stating that all experienced pilots undergo rigorous training, some aviation club members are experienced pilots, and therefore some members undergo rigorous training.
The correct answer exactly mimics the structural logic of the original argument. The original argument states: All A (botanists) are B (deep understanding). Some C (participants) are A (botanists). Therefore, some C (participants) are B (deep understanding). The correct option states: All A (experienced pilots) are B (rigorous training). Some C (club members) are A (experienced pilots). Therefore, some C (club members) are B (rigorous training). Both are logically valid and use the exact same distribution of quantifiers.

Step-by-Step Solution

1
Analyze the logical structure of the stimulus argument.
Premise 1: All Botanists (A) -> Plant Biology (B). Premise 2: Some Participants (C) -> Botanists (A). Conclusion: Some Participants (C) -> Plant Biology (B).
To identify the exact quantifier logic pattern that needs to be paralleled.
2
Determine the validity of the stimulus.
The argument is a perfectly valid deductive syllogism.
Parallel reasoning requires matching both the structural terms (quantifiers) and the validity of the argument.
3
Evaluate the options to find the identical structure.
The correct argument matches the 'All A are B, Some C are A, thus Some C are B' structure perfectly using pilots, training, and club members.
This guarantees identical quantifier logic and deductive validity.
