During an experiment, you were instructed to equally heat a sample of soil and a sample of water with heat lamps, and then measure the temperature of each sample once per minute, for eight minutes. Suppose that the experiment yielded the results shown in the table below. 

Which of the following predictions is best supported by the data?

• The temperatures of the soil and the water would rise at the same average rate because the same light is being used to heat it up.

• The temperature of the water would rise at a faster average rate than the average rate that the temperature of the soil would rise because water heats up faster than soil.

• The temperature of the soil would rise at a faster average rate than the average rate that the temperature of the water would rise because soil heats up faster than water.

•  The temperature of the soil would not rise at all over the next time period because the soil temperature has reached its maximum temperature.
