Question

1. all of the following are renewable energy sources that will never run out except. a) wind b) solar c) wood d) waves

case study. during the 1960s, as the country became more urbanized and population boomed, cities like los angeles and new york city were frequently shrouded in thick, dangerous smog caused by emissions from vehicles, factories, and power plants. this led to respiratory infections, lung cancer, and heart disease. a deadly six - day smog event in new york city in 1953, for example, killed more than 200 people. public concern about health led the u.s. government to pass laws that required limits on air pollution. also during this time in history, rivers in the u.s. were clogged with oil and factory waste. one famous river in ohio, the cuyahoga river, was so polluted it caught fire, which shocked the nation and made people demand cleaner waterways. that public pressure helped lead to national rules on industrial pollution into rivers and lakes.

1. which historical event helped lead to stronger rules on air pollution in the u.s.? a) the clean air act of 1972 reducing smog and other harmful pollutants in the atmosphere b) the 1972 ddt ban that canceled the use of spraying this chemical to protect wildlife c) the safe drinking water act of 1974 regulating contaminants in public water supplies d) the resource conservation and recovery act of 1976, regulating disposal of hazardous waste
2. similar to rivers described in the passage, a factory in 2025 begins dumping chemical wastes into a lake, making it polluted. which government environmental policy best addresses this problem? a) clean air act b) montreal protocol c) superfund act d) clean water act

Explanation:

Step1: Identify renewable energy sources

Renewable energy sources are those that can be replenished naturally. Wind, solar, and waves are renewable and will not run - out. Wood is a biomass energy source. While trees can be replanted, it is not an inexhaustible source like the others.

Step2: Answer question 16

The answer to question 16 is c) Wood as it is the non - inexhaustible renewable energy source among the options.

Step3: Analyze historical events for air pollution rules

The deadly smog event in New York City in 1953 led to public concern about health and the government passing laws on air pollution. The Clean Air Act of 1972 was a result of such concerns to reduce smog and other harmful pollutants.

Step4: Answer question 17

The answer to question 17 is a) The Clean Air Act of 1972 reducing smog and other harmful pollutants in the atmosphere.

Step5: Identify relevant environmental policy for water pollution

The Clean Water Act is designed to protect and improve water quality by regulating discharges of pollutants into water bodies. If a factory is dumping chemical wastes into a lake, the Clean Water Act is the most relevant policy.

Step6: Answer question 18

The answer to question 18 is d) Clean Water Act.

Answer:

1. c) Wood
2. a) The Clean Air Act of 1972 reducing smog and other harmful pollutants in the atmosphere
3. d) Clean Water Act
