Our Marine Chemist, John Snow, proposed a hypothesis that stated that the pH of the seawater in the area had dropped enough that the water was too acidic for corals to grow. Acidic water was therefore the major cause of damage to the reef system. Which statement best describes how John’s data relates to his hypothesis?

A. John carefully sampled that seawater around each reef in the system. He analyzed the data and found that there were slight variations in pH around the different reefs in the system. This data supported John’s hypothesis because it showed that these variations caused the major damage to the reef system.
B. John did some research and found that the pH values of the water in this area had fallen over the years. He sampled the water surrounding each reef in the system. The data he gathered supported his hypothesis because it confirmed that the pH of the seawater in this area continues to drop.
C. John gathered data on the pH of the seawater around each reef. This data supported John’s hypothesis because it showed that the water was too acidic for the coral to live.
D. John sampled the pH of the seawater at each site around the reef system. His analysis of the average pH in the area showed that the pH was still in an acceptable range to allow the coral to live and grow. This data did not support John’s hypothesis.
I don't like these answer choices. There is nothing about historical reef growth/size data, which is also important to study, so we can find a correlation between the pH level and reef growth rate or size of the reefs.
Assuming there is already an established correlation between pH level and reef growth, I would chose answer B.
He observes both historical data and current data, thereby reinforcing the idea that the pH water is continuing to drop. None of the other choices make use of historical data, which is necessary to support John's hypothesis that the pH level is continuing the drop.
