Based on the information provided within the question it can be said that the research experiment conducted in this scenario indicates that memories are not located in single, specific locations in the brain. That is because the researcher removed various pieces of the where memories should be located in the brain and yet the rats were still able to recall how to solve the maze.

i believe the answer is a or 1
