Air pollution from a power plant is being monitored for levels of nitrogen dioxide and ground-level ozone. The levels are measured daily at the same time. Which of the following best predicts the impact of a dark and cloudy day on the readings for the levels of air pollutants measured?

Scientists want to examine the effects of a coal-burning power plant on the pH of a lake that is downwind of the power plant. They take samples from a lake that is not downwind of the power plant to serve as a control. However, they did not realize that the lake they chose as a control group was a geothermal hot spring with acidic water.
Using this control would not have an effect on the outcome because the high temperature of the hot spring reduces the acidity of the water in the lake.
The coal-burning power plant would appear to have a much larger effect on the pH of the experimental group because the
pH in the control lake would be elevated from the acidic water.
The coal-burning power plant would not appear to have a large impact because the pH levels of the two lakes would be similar.
The coal-burning power plant would affect both lakes because the Coriolis effect and weather patterns would circulate pollutants in the atmosphere.
