Gina convinces Jordan to use the solar cooker to prepare their meal. Jordan takes the cooker outside and places it under a large shade tree in their backyard. Gina explains that for the solar cooker to work, they should place it in a different location. Gina and Jordan need to find a better location for the solar cooker. Which of the following best describes what they should do?

• The solar cooker should be placed near the house so they can plug it in.

• The solar cooker should be placed in a location where the wind is blowing.

• The solar cooker should be placed in the house because it is warmer inside.

• The solar cooker should be placed in a location that gets as much sunlight as possible.
