Question

read the claim below. the practice of large - scale aquaculture, or \fish farming,\ should be banned. select the piece of evidence that best supports this claim. aquaculture can contaminate water systems with the pesticides and antibiotics used to treat farm - raised fish. the majority of farmed atlantic salmon imported into the united states comes from canada, norway, and chile. aquaculture makes more food available to a growing world population in which hunger affects one in nine.

Explanation:

The claim is that large - scale aquaculture should be banned. The first piece of evidence about water contamination with pesticides and antibiotics used in aquaculture directly relates to a negative impact (contamination) of aquaculture, which supports the idea of banning it. The second piece of evidence about the origin of imported salmon is just a geographical fact and does not support or oppose the ban. The third piece of evidence about aquaculture providing more food is a positive aspect of aquaculture and would oppose the ban.

Answer:

Aquaculture can contaminate water systems with the pesticides and antibiotics used to treat farm - raised fish.
