Question 6 - Science Practice Test for the GED Test

The test results show that the rats that were fed with highly processed grains solved the maze at a slightly slower pace than those fed with a plant-based diet. Based on these results, is the experiment finished?

A scientist is studying the effects high levels of processed grains have on the mind by feeding them to rats. The scientist has an idea in his head as to what the results will be, but he would like to confirm this. His idea is that rats fed with highly processed grains will not think as clearly as those fed a healthier diet. To perform his experiment, he feeds a specific amount of highly processed grains to one sample of rats for a set amount of time, while the others are fed a diet of plant-based foods. Each set of rats is then sent through a maze individually and timed to determine the speed at which they are able to solve the maze.
