Answer

Brief Explanations:

The text describes Tryon's experiment with rats in a maze. It then states the conclusion from the experiment: that the ability to navigate the maze was influenced by genes passed from parent to offspring. This shows the significance of the experiment. The text is not mainly about highlighting Tryon's contributions in a general sense (it focuses on one experiment's significance), not about the general role of rats in research, and the conclusion is that genes "influenced" not that they are "solely responsible".

Answer:

to explain the significance of Tryon's experiment
