Explanation:

Question #1

To conserve nonrenewable resources (like petroleum, coal, natural gas which are fossil fuels), we analyze each option:

• Option A: Petroleum and coal are nonrenewable and can't be reused in the way implied (they are consumed when used, not easily reused).
• Option B: Reducing production of electronic devices reduces demand for resources (including nonrenewable ones used in electronics like rare earth metals, fossil fuels for energy in production). This helps conservation.
• Option C: Replacing wind (renewable) and geothermal (renewable) with natural gas (nonrenewable) increases use of nonrenewable, so it's bad for conservation.
• Option D: Fossil fuels can't be recycled into other products in a way that conserves them (they are burned for energy, the process is consumption, not recycling like materials).

So the correct action is reducing electronic device production.

Rensing (reusing) a resource means using the same resource again without transforming it into something new or reducing use (which is reducing, not reusing).

• Option A: Burning wood for fuel is using it as fuel, not reusing (it's a single use of the wood).
• Option B: Making new products from used plastic bottles is recycling (transforming), not reusing.
• Option C: Using less packing material is reducing, not reusing.
• Option D: Using the same drinking glass for water is reusing the glass (using it multiple times for the same purpose without changing it).

So the best example of reusing is using the same drinking glass.

Hybrid vehicles (electric - gasoline) are designed to be more fuel - efficient. Let's analyze each option:

• Option A: Hybrids are not primarily designed for more horsepower; often gasoline engines in hybrids are smaller, so horsepower is not the main goal.
• Option B: Hybrids still use gasoline (a fossil fuel) and produce some greenhouse gases (though less than pure gasoline), so they don't eliminate greenhouse gas emissions.
• Option C: Hybrids still use gasoline (a fossil fuel), so they don't operate independently of fossil fuels.
• Option D: Hybrids use a combination of electric and gasoline power to get better gas mileage (more miles per gallon of gasoline), which is their primary design goal.

So the primary design goal is better gas mileage.

Answer:

B. reducing the production of electronic devices
