Answer:
Explanation: The town in the Finger Lakes region should promote the solution of decreased motor boat traffic on the lake. Acidification is mainly caused by the high levels of carbon dioxide that enter the water from the atmosphere, and motor boat traffic can worsen this by increasing the amount of carbon dioxide in the air. Reducing motor boat traffic on the lake would help to decrease the amount of carbon dioxide entering the water, and thus reduce acidification. The other solutions listed (increased introduction of zebra mussels, decreased use of CFCs, and protecting fish species) may have other environmental benefits, but they are not directly related to reducing acidification.
