Answer 1

A person burns a fuel to get energy in the following situations:

• When driving a car (most cars use gasoline or diesel, which are fuels that are burned to power the engine).
• When tending a campfire on a cold night (burning wood or other materials in a campfire produces heat and light).

The other options do not involve burning fuel for energy:

• When leaving ice cream out on a hot day (this involves the melting or spoilage of ice cream due to heat, not fuel combustion).

• When hanging wet clothes outside to dry (this is a drying process that relies on evaporation and does not involve burning fuel).

So the applicable responses are:

• when driving a car
• when tending a campfire on a cold night
