Here are responses to your questions based on common knowledge regarding energy sources, recycling, environmental science, and water conservation:
-
Problem with using oil as an energy source: One major problem with humans using oil as an energy source is that it contributes to environmental pollution and climate change. The combustion of oil releases greenhouse gases, which trap heat in the atmosphere and lead to global warming.
-
Alternatives to using oil and fossil fuels: Some alternatives to oil and fossil fuels include renewable energy sources such as solar power, wind power, hydroelectric power, geothermal energy, and biomass. These alternatives reduce greenhouse gas emissions and help mitigate climate change.
-
Types of items that can be recycled: Common items that can be recycled include paper (newspapers, cardboard), plastics (bottles, containers), metals (aluminum cans, tin cans), glass (bottles, jars), and certain electronics. Many communities also offer recycling programs for specific items.
-
Ways scientists and engineers help protect the planet: Scientists and engineers contribute to environmental protection by developing clean energy technologies, designing sustainable products, improving waste management systems, researching ecosystems and biodiversity, and innovating ways to reduce pollution and carbon emissions.
-
Example of preserving fresh water: One simple action you can take to help preserve fresh water is to reduce water usage by taking shorter showers, fixing leaks in plumbing, collecting rainwater for gardening, or using water-efficient appliances.
-
Type of scientist that helps save the planet: One type of scientist that helps save our planet is an environmental scientist. Environmental scientists study the environment and use their findings to develop solutions to environmental problems, promote sustainability, and advocate for policies to protect natural resources.

Water usage for a 10-minute shower a day: If Adam takes a 10-minute shower every day, and assuming an average shower uses about 10 liters per minute, he would use: \[ 10 \text{ minutes/day} \times 10 \text{ L/min} \times 365 \text{ days} = 36,500 \text{ L/year} \] However, if the answer choices provided were 4,000 mL, 40,000 mL, 14,610 L, or 40 L, the closest answer based on the average assumptions would probably be 40,000 mL (which is equivalent to 40 L), but it appears the calculation needs a perspective acknowledgment since it's above, it should ideally assess 14,610 L as well based on variable water usage.
