Passage B(228 more words not shown)

Both passage A and passage(7 more words not shown)

Reading the passage

What do both discussions do? A moves from the tension between established knowledge and new ideas to Darwin's habits. B states three needed modes of thought, then contrasts the researchers with their community. We need a description that fits both structures, rather than one memorable detail.

Working the answers

  • A
    Correct

    A gives a general account of balancing established theories with openness to alternatives. B says scientists need to be “curious,” “creative,” and “critical.” Each therefore presents a view about scientific thinking and develops it through examples.

  • B

    B describes the community's response to Arp and Tifft's challenge. A doesn't focus on how the community reacted to a particular Darwinian theory.

  • C

    B criticizes the astrophysics community's attitude. A praises Darwin without making a corresponding criticism of his community.

  • D

    Only A gives a volume of correspondence: more than 16,000 letters.

  • E

    Only A explicitly invokes a view of scientific history as a series of paradigm shifts. B discusses how scientists should investigate an anomaly without invoking that historical model.
