The average quantity of water in the lakes of the village of Criota has decreased by 10% this summer. Since fish population is usually proportional to the average quantity of water in a lake, the village head predicted that their net revenue from the sales of fish to neighboring villages will also decrease by about 10%. However, this revenue decreased by only 1% this summer. This less-than-expected decrease has been attributed to the fact that large quantities of black soil, which is rich in nutrients required for growth of fish, has been dumped into the lakes of Criota.
Which of the following statements, if true, provides the best support for the attributed causality?
A. Black soil is also found in ponds where shrimps can be farmed quite effectively.
B. Other villages that faced a water shortage and dumped black soil in their lakes had a larger harvest of fish than was predicted based on the corresponding shrinkage of water.
C. Because of the recent acid rains, more than 10% of the fish population in the lakes of Criota has died prior to summer this year.
D. Black soil is quite favorable for aquatic algae and fungi to feed and thrive on, doubling their populations within as few as 10 days.
E. A decrease in the revenue from fish sales usually impacts the fish farmers’ ability to maintain their business profitably.

Conclusion: This less-than-expected decrease has been attributed to the fact that large quantities of black soil, which is rich in nutrients required for growth of fish, has been dumped into the lakes of Criota.
Clear causality argument.
How can we strengthen "1 causes 2" ? Show that 1 doesn't cause 2 or show that When 1 occurs, 2 occurs.
Now replace 1 and 2 as mentioned below
1 -> dumping of black soil 2 -> increase in fish population
Option B wins hands down.
A: Nothing known about shrimp's impact on fish sales C: It's a Weakener D: Nothing known about fungi's impact on fish sales E. Irrelevant
