While researching the impact of urban heat islands, a student took the following notes: * Some cities use reflective 'cool roofs' to lower temperatures. * Reflective surfaces bounce solar radiation back into the atmosphere. * In Los Angeles, cool roofs reduced ambient temperatures by 2 degrees. * In Chicago, the same technology showed a reduction of 1.5 degrees. The student wants to emphasize a similarity between the two cities. Which choice most effectively uses relevant information from the notes to accomplish this goal?

1. While Los Angeles saw a 2-degree drop, Chicago saw a 1.5-degree drop in temperature using reflective surfaces.
2. Reflective surfaces are a common urban intervention used to bounce solar radiation away from metropolitan areas like Chicago.
3. Los Angeles and Chicago both experienced a decrease in ambient temperature after implementing cool roof technology.
4. Cool roof technology works by reflecting solar radiation, which helped Los Angeles lower its temperature by 2 degrees.
