Some organisms dwelling in the abyssal zone are bioluminescent. Since no bioluminescent organisms possess functioning chloroplasts, it follows that some organisms dwelling in the abyssal zone do not possess functioning chloroplasts.
Which of the following arguments exhibits a pattern of reasoning most logically similar to that exhibited by the argument above?
- Some contemporary novels are written entirely in verse. Since no books written entirely in verse are easily translated, it follows that some contemporary novels are not easily translated.Answer
- BMost contemporary novels are written entirely in verse. Since no books written entirely in verse are easily translated, it follows that most contemporary novels are not easily translated.
- CSome contemporary novels are written entirely in verse. Since no contemporary novels are easily translated, it follows that no books written entirely in verse are easily translated.
- DSome contemporary novels are written entirely in verse. Since all books written entirely in verse require careful reading, it follows that some contemporary novels require careful reading.
- ESome contemporary novels are not written entirely in verse. Since no books written entirely in verse are easily translated, it follows that some contemporary novels are easily translated.
Answer
The argument about contemporary novels that are not easily translated.
The correct argument matches the exact logical blueprint of the original passage. Let A = contemporary novels, B = written entirely in verse, and C = easily translated. The structure is 'Some A are B. No B are C. Therefore, some A are not C.' This perfectly mirrors the 'Some A are B. No B are C. Therefore, some A are not C' structure of the stimulus.
