It was difficult to check because you didn't number your questions and answers.

I disagree with your answers for 4, 6, 8, and 9. I don't know about 7.

a. free-access resource

To determine the correct answer to each question, let's go through each option and evaluate them based on the description provided.

Question 1: Which of the following is an example of recycling?
Recycling is the process of converting waste materials into reusable materials. Let's evaluate each option:

a. Collecting and remelting aluminum beer cans - This is an example of recycling, as aluminum can be melted and reused.
b. Cleaning and refilling soft-drink bottles - This is also an example of recycling, as the bottles are being reused instead of being disposed of.
c. Selling used clothing at a garage sale - This is not an example of recycling, as it involves selling used clothing rather than reusing or converting it into new materials.
d. Saving leftovers in a peanut butter jar - This is not an example of recycling, as it refers to reusing containers for storing leftovers.
e. Using household water to water a garden - This is not an example of recycling. While it may be a sustainable practice, it does not involve the conversion of waste materials into reusable materials.

Therefore, options a and b are examples of recycling.

Question 2: Point sources of pollution
Point sources of pollution can be identified as specific and identifiable sources of pollution. Let's evaluate each option:

a. Enter ecosystems from dispersed and often hard-to-identify sources - This contradicts the definition of point sources as it refers to nonpoint sources.
b. Include runoff of fertilizers and pesticides from farmlands and suburban lawns - This is an example of nonpoint sources of pollution, as it does not come from a specific point or identifiable source.
c. Are cheaper and easier to identify than nonpoint sources - This is not true. Point sources are generally easier to identify than nonpoint sources.
d. Are more difficult to control than nonpoint sources - This is not true. Nonpoint sources are generally more difficult to control than point sources.
e. Are always found in rural areas - This is not true. Point sources can be found in both urban and rural areas.

Therefore, option b is the correct answer as it describes nonpoint sources of pollution.

Question 3: You generally buy and eat microwave dinners. After dinner, cardboard tops and plastic trays remain. The least effective way to deal with this type of solid waste problem is to
Evaluate each option:

a. Store leftovers in the plastic trays - This is not the most effective way, as the trays are not biodegradable and will contribute to solid waste.
b. Put all of the solid waste in the household trash to be taken to the landfill - This is not the most effective way, as it results in the waste going to a landfill instead of being properly disposed of or recycled.
c. Donate the plastic containers to the local nursery schools to use with preschoolers - While this option promotes reuse, it does not address the issue of producing waste in the first place.
d. Recycle the components - This is the most effective way to deal with the solid waste problem, as it involves converting the materials into reusable resources.
e. All of these are effective - This is not the correct answer, as options a, b, and c are not the most effective ways to deal with the solid waste problem.

Therefore, option d (recycling the components) is the correct answer.

Question 4: Efforts to improve environmental quality in the United States are predominantly based upon __________ wastes and pollutants.
Evaluate each option:

a. Reducing - This is one of the main efforts to improve environmental quality, but it is not the only one.
b. Reusing - This is another effort to improve environmental quality, but it is not the only one either.
c. Recycling - This is another effort to improve environmental quality, but it is not the only one.
d. Cleaning up - This is another effort to improve environmental quality, but it is not the only one.
e. There are no efforts to improve environmental quality in the United States - This is not true, as there are various efforts in place to improve environmental quality.

Therefore, option e is the correct answer, as efforts to improve environmental quality in the United States are based on reducing, reusing, recycling, cleaning up, and other methods.

Question 5: Pollution prevention and cleanup can be encouraged by
Evaluate each option:

a. Regulations - This is one way to encourage pollution prevention and cleanup.
b. Taxes - This is another way to encourage pollution prevention and cleanup.
c. Subsidies - This is another way to encourage pollution prevention and cleanup.
d. Education - This is another way to encourage pollution prevention and cleanup.
e. All of these answers - This is the correct answer, as all of the mentioned options can be used to encourage pollution prevention and cleanup.

Question 6: Two children in the United States have as much environmental impact as __________ children in the world's poorest countries.
Evaluate each option:

a. 5-10 - This is not the correct answer, as it does not match the description.
b. 10-20 - This is not the correct answer, as it does not match the description.
c. 50-100 - This is not the correct answer, as it does not match the description.
d. 70-200 - This is not the correct answer, as it does not match the description.
e. 90-300 - This is the correct answer, as it states that two children in the United States have a similar environmental impact as 90-300 children in the world's poorest countries.

Question 7: Which of the following pieces of evidence is likely to form the basis of an environmentalist's opinion?
Evaluate each option:

a. The rate of human population growth is declining - This is a piece of evidence that supports the need for environmental conservation, as it suggests that a declining population growth rate can alleviate some environmental pressures.
b. Food is more abundant and cheaper than at any other time in human history - This is a piece of evidence that does not directly align with the need for environmental conservation, as it focuses on the availability and affordability of food.
c. Total forest area of the temperate zone region's industrialized countries increased during the 1980s - This is a piece of evidence that suggests positive environmental change but does not represent the entire basis of an environmentalist's opinion.
d. Consensus science suggests that potential global climate change from human activities should be taken as a serious problem - This is a piece of evidence that supports the need for environmental conservation, as it acknowledges the potential impacts of human activities on climate change.
e. All of these answers - This is the correct answer, as all of the mentioned pieces of evidence can form the basis of an environmentalist's opinion.

Question 8: Which of the following is NOT one of the five basic causes of the environmental problems we face?
Evaluate each option:

a. Poverty - This is one of the basic causes of environmental problems.
b. Rapid population growth - This is one of the basic causes of environmental problems.
c. Biodiversity depletion - This is one of the basic causes of environmental problems.
d. Unsustainable resource use - This is one of the basic causes of environmental problems.
e. Not including the environmental costs of economic goods and services in their market prices - This is one of the basic causes of environmental problems.
f. Trying to manage and simplify nature with too little knowledge about how it works - This is NOT one of the five basic causes of environmental problems.

Therefore, option f is the correct answer.

Question 9: A resource that is owned by no one (or jointly by everyone in a country or area) but is available to all users at little or no charge is known as a
Evaluate each option:

a. Free-access resource - This is one of the correct answers.
b. Renewable resource - This is not the correct answer, as a renewable resource refers to a resource that can be replenished naturally.
c. Community resource - This is not the correct answer, as a community resource refers to resources that are owned and managed collectively by a specific community.
d. Common-property resource - This is another correct answer.
e. All of the above - This is not the correct answer, as option b is not applicable.
f. None of the above - This is not the correct answer, as options a and d are applicable.
g. Both "a" and "c" - This is not the correct answer, as option c is not applicable.
h. Both "a" and "d" - This is the correct answer, as options a and d both describe a resource that is owned by no one (or jointly by everyone) and is available to all users at little or no charge.

Therefore, option h is the correct answer.
