LSAT Preptest 154, Section 1, Question 15

"In the winter, ravens survive by…"

Explanation

The passage describes a study by Bernd Heinrich on raven behavior. Now we need to determine which option best fits the description of Heinrich's study as reported.

A. The passage does not mention Heinrich proposing two alternative hypotheses; it only describes his observations and findings about raven behavior. 


B. (Correct Response) The passage suggests that while Heinrich's findings align with prior observations that ravens recruit others to eat a carcass, his interpretation of the behavior offers a new perspective, indicating territorial behavior and group strategy among ravens, which could be seen as a "radical reinterpretation." 


C. The passage does not explicitly state that Heinrich had a pre-existing theory that he then confirmed; it simply reports his observations and conclusions based on those observations. 


D. The passage does not compare Heinrich's methods to those of earlier studies, nor does it claim that he arrived at the same conclusion as previous studies. 


E. There is no indication that Heinrich's investigation replicated previous studies, nor does the passage comment on the scope of observational data relative to previous studies.

The description of Heinrich's study fits best with option B, as it indicates that his investigation confirmed aspects of previously observed raven behavior but also led to a new understanding of that behavior.
