1. It allows the scientist to determine the effect of the changed variable.
Let's say there was an experiment showing the effect of water on plant growth. The environment (in this case, the other variables including the amount of sunlight) would need to be kept under control in order for the results to be clear. If there was a different amount of sunlight during each trial, then the results would be effected by both the water and sunlight, making the results incorrect for the experiment.
Answer: The options are not given, here are the options.
Water flows from a stream to a lake.
Gravity moves rocks to another location.
Lions use energy to catch other animals for food.
