Explanation
The given answer is correct because it accurately identifies the trends in the data presented. It states that there was an exponential rise in production between 1955-1980, which is evident from the increasing trend in the graph during that period. It also mentions a steady increase in the adjusted price from 1975-1985, which is supported by the upward slope of the line representing the adjusted price during that time. Lastly, it correctly states that natural gas prices remained stagnant from 1930-1973, as indicated by the flat line representing prices during that period.

Explanation
If a beach is in the vicinity of an oil spill, the tourism sector will be greatly affected. This is because the beach is a popular destination for tourists, and an oil spill can lead to contamination of the water and shoreline, making it unsafe and unattractive for visitors. The presence of oil can harm marine life, damage the ecosystem, and create a negative perception of the beach as a polluted and hazardous environment. As a result, tourists are likely to avoid the area, leading to a decline in tourism activities and revenue for businesses dependent on tourism.

Explanation
Living closer to refineries can increase the risk of developing cancer due to exposure to harmful pollutants and chemicals released during the refining process. Refineries emit various carcinogens such as benzene, formaldehyde, and sulfur dioxide, which can have long-term health effects on nearby residents. These pollutants can enter the air, water, and soil, leading to potential inhalation, ingestion, or absorption into the body. Prolonged exposure to these toxic substances increases the likelihood of developing various types of cancer, including lung, bladder, and leukemia. Therefore, individuals living in close proximity to refineries are more susceptible to cancer.

Explanation

Explanation
In rotary drilling, a large, heavy bit is attached to a length of hollow drill pipe.

Explanation
The United States consumes the most energy in the world. This is because the United States has a large population and a highly developed economy, which leads to a high demand for energy across various sectors such as industry, transportation, and residential. Additionally, the United States has a high standard of living, which also contributes to its high energy consumption. The country relies heavily on fossil fuels, particularly oil and natural gas, for its energy needs.

Explanation
The United States is the correct answer because it is currently the largest producer of energy in the world. It has a diverse energy portfolio that includes fossil fuels like coal, oil, and natural gas, as well as renewable sources such as wind, solar, and hydroelectric power. The United States has a highly developed energy infrastructure and invests heavily in energy production, allowing it to generate a significant amount of energy to meet its domestic and international demands.

Explanation
Oil is the leading source of energy in the US because it is widely used for transportation, heating, and electricity generation. The US heavily relies on oil for its energy needs, with a significant portion being imported from other countries. Oil is used in various sectors of the economy, including the automotive industry, aviation, and manufacturing. It is a versatile and easily accessible source of energy, making it the primary choice for meeting the energy demands of the country.

Explanation
Styrofoam is a type of plastic made from polystyrene, which is derived from crude oil. Crude oil is a non-renewable fossil fuel that takes hundreds of years to decompose naturally. Therefore, a styrofoam cup, being made from crude oil-based material, would also take a long time to decompose. In this case, it would take approximately 400 years for a styrofoam cup to decompose.

Explanation
Salt makes your body hold onto water. When you consume salt, it increases the concentration of sodium in your body. Sodium attracts water and causes your body to retain more water. This can lead to water retention and bloating.

Explanation
Approximately 80% of salt is "hidden" in processed foods. This means that a large majority of the salt we consume comes from processed foods rather than from adding salt to our meals or cooking. It is important to be aware of this hidden salt content in order to make healthier choices and reduce our overall salt intake.

Explanation
A teaspoon of salt is the correct answer because the American Heart Association recommends that teenagers should consume no more than 2,300 milligrams (about one teaspoon) of salt per day. Consuming excessive amounts of salt can lead to high blood pressure and other health problems, so it is important for teenagers to limit their salt intake to maintain good health.

Explanation
Too much salt increases the risk of having strokes and heart disease. This is because excessive salt intake can lead to high blood pressure, which is a major risk factor for heart disease. High blood pressure puts strain on the heart and blood vessels, increasing the likelihood of developing heart disease.

Explanation
Salt is made up of two chemicals, sodium and chlorine. Sodium is a highly reactive metal, while chlorine is a toxic gas. When sodium and chlorine combine, they form a stable compound called sodium chloride, which is commonly known as salt. Sodium chloride is essential for various biological processes and is commonly used as a seasoning in food.
