Answer:
A. Recent environmental research reveals that the dust from the limestone quarrying site has severely contaminated the water at a nearby lake.
Explanation:
The limestone production results in huge social effects like, noise pollution, soil pollution, which affects lives of people. And since the manufacturers or producers of limestone do not care about the social results of such production, they shall be liable to pay huge taxes.
As for this, the cause as stated in statement A is absolutely suitable.
Also the prices are more in this area even after so much of social destruction.
Accordingly high taxes as a penalty for such social destruction shall be charged.

According to the passage, which mechanism explains the observed changes in fish size over time?
A. Smaller fish produce fewer eggs than larger fish do, so they contribute fewer offspring to the next
generation.
B. Fish that are small enough to escape fishing nets are more likely to survive than larger fish.
C. Scientists found that Atlantic silversides exhibited changes in feeding and foraging rates after four

Answer:
C. Shut down the presses printing my book
Explanation:
Since the average variable cost of producing the book is above the demand curve, the best course of action is to shut down the printing (production) of more books. The author would lose less money by shutting down operations rather than continuing production at a variable cost higher than the demand he's receiving for the books. 
In economics, when profit is less than the average variable cost, firms are advised to stop production in the short run and incur economic loss on fixed inputs. This is because with continued operations, total revenue would not only be lower than total cost, but rather, would also be less than total variable cost.
