Shortly after the power plant opened and began discharging its wastewater into the river, there was a decrease in the overall number of bass caught by anglers downstream from the plant.
Each of the following, if true, could explain the decrease described above EXCEPT:
The discharged wastewater made the river more attractive to fish that are the natural predators of bass.
The discharged water was warmer than the normal river temperature, leading the bass to seek cooler water elsewhere.
Because of the new plant, access to the part of the river downstream from the plant was improved, leading to an increase in the number of anglers fishing for bass.
Because of the new plant, the level of noise downstream increased, making that section of the river a less popular place for anglers to fish.
The discharged wastewater created turbulence that disrupted the vegetation of the river downstream, destroying some of the bass's natural habitat.
