ANSWER KEY EXAM 172

1. Answer: B

The Environmental Protection Agency (EPA) defines the greenhouse effect as "a natural phenomenon that helps regulate the earth's temperature." Greenhouse gases include carbon dioxide, methane, nitrous oxide and chlorofluorocarbons. They act like an "insulating blanket" and prevent solar energy from escaping into space. Without this natural protection, the earth's temperature would be about 60°F lower and life as we know it would be unsustainable. Since the late eighteenth century, humans have significantly contributed to the greenhouse effect by burning fossil fuels such as coal and oil and reducing the number and density of forests. Worldwide populations are more concentrated. Because of this human shift, greenhouse gas emissions are increasing. According to the EPA, "human activities have caused the atmospheric concentrations of carbon dioxide and methane to be higher today than at any point during the last 650,000 years. Scientists agree that it is very likely that most of the global average warming since the mid-20th century is due to human-induced increases in greenhouse gases rather than to natural causes."

2. Answer: C

Wetlands link land and water resources. Programs to protect wetlands usually work with programs designed to protect and manage other surface and ground water systems. These programs include storm, flood and pollution control, protection of fish and wildlife and creation and maintenance of public recreation areas. A watershed or drainage basin is the area where water, sediment and other material flows from a landmass into a body of water, i.e., river, lake, ocean or sea. Watershed conservation programs take a systemic approach and consider the entire ecosystem including water, air and land. A floodplain is a low area of land next to a body of water. Floodplains and adjacent water resources form a complex, dynamic ecosystem, which provides flood and erosion control, water filtering, natural habitats for plants and animals and areas for public recreation and scientific study.

3. Answer: C

The Environmental Protection Agency (EPA) is involved with various activities and works with other federal and state agencies, private industry and environmental organizations to develop plans to protect the environment and manage water resources and the surrounding land using a watershed protection approach. The EPA issues periodic reports on the condition of the nation's wetlands (areas that link land and water resources), watersheds (drainage basins where water, sediment and other material flows from a land mass into a body of water) and floodplains (a low area of land next to a body of water). One of the agency's missions is to preserve, protect and maintain the quality of our water resources. They are accountable to the American people for the success or failure of their efforts.

4. Answer: A

A Contract is a legally binding promise that explains what each person agrees to do, provide or act on in exchange for adequate consideration (expected benefits). A contract may be a written document or a verbal agreement and a handshake. Both versions are recognized and enforced by state and federal courts. In order for a contract to be legally binding, all signers must be of legal age (in most states eighteen) and of sound mind (able to understand the terms of the agreement). A Bill-Of-Sale is a legal document certifying the transfer of ownership from one person, company or entity to another person, company or entity. The new owner needs it to prove ownership in order to transfer titles and deeds into his name or his company's name.

5. Answer: B

The Uniform Commercial Code is a set of rules and provisions enacted to simplify and clarify commercial transactions with uniform laws that govern all jurisdictions. If a transaction involves two or more states or another nation, the provisions of either may be applied as long as all the parties involved agree which code is to be used. Both buyer and seller have certain rights. When a buyer purchases an item, he receives clear title. He accepts in good faith the seller legally owned the item and had authorization to sell it and transfer ownership. The buyer has the right to take possession according to the terms of the sale. If the buyer refuses to take delivery, fails to make the agreed upon payment as specified in the terms of the sale or payment is rejected (insufficient funds, buyer insolvency, etc.), the seller may cancel the sale; stop delivery; resell the item to recover any monetary loss incurred; demand return of the title and other paperwork provided at the time of the sale.
