Which of the following is most responsible for the change in the emissions of volatile organic compounds ( VOC ) from 1970 to 2020 as shown in the graph? in the graph, annual vehicle miles went up as the years went by, and VOCs went down.

An increase in air emission standards that began in 1970 that regulated corporate average fuel economy (CAFE ) standards. Correct. In 1970 the Clean Air Act, which was passed and amended in 1977 and 1990, targeted emissions from vehicles (nitrogen oxides and hydrocarbons specifically) and required the use of catalytic converters on vehicles. Corporate Average Fuel Economy (CAFECAFE) standards were enacted in 1975 to improve the average fuel economy of cars and light trucks produced for sale in the United States, leading to the trends seen in the graph. Although the number of miles has increased, the VOCVOC emissions have decreased.

Effects of Noise on Wildlife Sound, just like the availability of nesting materials or food sources, plays an important role in the ecosystem. Activities such as finding desirable habitat and mates, avoiding predators, protecting young, and establishing territories are all dependent on the acoustical environment. [Wildlife is] being forced to adapt to increasing noise levels. Research shows that males of at least one frog species are adapting to traffic noise by calling at a higher pitch. This could be problematic for the females, because they prefer lower-pitched calls, which indicate larger and more experienced males. In general, studies indicate that animals are stressed by noisy environments. The endangered Sonoran pronghorn avoids noisy areas frequented by military jets; female frogs exposed to traffic noise have more difficulty locating the male's signal; bats avoid hunting in areas with road noise. Combined with other stressors such as winter weather, disease, and food shortages, sound impacts can have important implications for the health and vitality of wildlife populations within a park. National parks are under increasing noise pressure. Noise levels in park transportation corridors today are many times the natural level. Sound levels during peak periods in a high air traffic corridor in the Yellowstone backcountry, for example, were elevated by up to 5 decibels. The result is as much as a 70% reduction in the size of an area in which predators can hear their prey. Increasingly, careful consideration of the impacts of human-generated noise on wildlife is a critical component of management for healthy ecosystems in our parks. Based on the author's claim in the article, which of the following statements best describes the effect of noise pollution on wildlife?

D) Noise pollution has a negative effect on wildlife activities such as mating, establishing territories, and predator-prey interactions.

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. Which of the following best describes how their choice of control group could affect the results of their experiment?

The coal-burning power plant would not appear to have a large impact because the pH levels of the two lakes would be similar Correct. Acid rain, as a result of pollution from the plant, would increase the acidity of the lake. If the scientists are using a control that also has acidic water, the effect of the plant would appear to be minimal because the difference in pHpH would be lower than if they used a nonacidic lake as a control

There will be an increase in the level of nitrogen dioxide and a decrease in the level of ground-level ozone. Ground-level ozone is a secondary pollutant that forms from nitrogen oxides and volatile organic compounds, catalyzed by ultraviolet (UV) light. Cloud coverage would reduce the amount of UV light (sunlight) reaching Earth, which would result in reduced ozone formation. Levels of nitrogen dioxide would be expected to be higher as a result of decreased ground-level ozone production.

An air pollution expert set up a monitoring program to determine the amount of particulate matter (PM) leaving a farmer's field after crops were harvested and the soil was bare. She set up high-volume air samplers 10 meters from each edge of the square field and collected samples weekly for two months.

Which of the following is the most likely reason for the trend shown in the graph of fluctuating indoor radon levels over the course of a year? in the colder months, radon was higher, and in the warmer months, it was lower.

Radon levels tend to increase in the colder months because of the difference in temperature inside and outside the home, which creates a vacuum pulling radon into the home at a higher rate. Correct. Radon levels tend to increase in the colder months owing to the difference in temperature inside and outside the home. If the outside temperature is drastically lower than the indoor temperature, then a vacuum is created within the home as the warm, indoor air circulates. This vacuum pulls radon into the home at a faster rate than normal, resulting in elevated radon levels.

Noise Exposure and Public Health Exposure to noise constitutes a health risk. There is sufficient scientific evidence that noise exposure can induce hearing impairment, hypertension and heart disease, annoyance, sleep disturbance, and decreased school performance. For other effects such as changes in the immune system and birth defects, the evidence is limited. Most public health impacts of noise were already identified in the 1960s, and noise abatement is less of a scientific but primarily a policy problem. A subject for further research is the [clarification] of the mechanisms underlying noise-induced cardiovascular disorders and the relationship of noise with annoyance and nonacoustical factors modifying health outcomes. A high-priority study subject is the effect of noise on children, including cognitive effects and their reversibility. Noise exposure is on the increase, especially in the general living environment, both in industrialized nations and in developing world regions. This implies that in the twenty-first century noise exposure will still be a major public health problem. Which of the following best describes why the authors do not claim that noise exposure induces birth defects in humans?

There is insufficient evidence to support that noise exposure induces birth defects in humans. The third sentence of the passage is "For other effects such as changes in the immune system and birth defects, the evidence is limited." Therefore, the author did not make this claim.
