Question

in the 1940s, behavioral psychologist robert tryon conducted an experiment in which rats were placed in a complex maze that had a food reward at one exit. rats that made fewer errors navigating the maze were bred together to create a \maze - bright colony.\ rats that made more errors were bred together to create a \maze - dull colony.\ after selectively breeding the mice for seven generations, tryon tested offspring from each colony to determine how quickly those rats would learn the maze. offspring of the maze - bright rats consistently made fewer errors than the maze - dull offspring. tryons research, therefore, suggests that the ability to navigate the maze successfully was influenced by genes passed from parent to offspring. who is the primary audience? (a) people who own rats (b) biology students (c) professional psychologist

Explanation:

The passage describes an experiment by Robert Tryon. He tested rats' maze - navigating abilities over generations and selectively bred them to create "maze - bright" and "maze - dull" colonies. The question asks about the primary audience for this work. Given the context of the research on rats and its nature as a behavioral study, the primary audience would be people who own rats as they might be interested in the behavioral and genetic aspects of their pets.

Answer:

a) people who own rats
