Fish breeder: A rare illness known as Smith-Kreal disease is spreading

Fish breeder: A rare illness known as Smith-Kreal disease is spreading continuously and has already killed 19% of our fish. I recommend that we drain and refill the ponds while executing some form of isolation operation.

Exporter: That would not help. We should feed the fish with increased doses of vitamins to strengthen their immune systems against any viral attack.

Which of the following, if true, most weakens the exporter's suggestion?


A. The Smith-Kreal disease, first identified and investigated by Erwin Smith and Jason Kreal, is so violent that it can overpower any form or level of biological defense a fish may have. Correct

any medication will not help to decrease Smith-Kreal disease

B. The drainage of a fish-breeding pond can be a stressful event that can result in the unnecessary death of many fish. Incorrect

weakens Fish breeder argument

C. Diseases in fish can be prevented by strengthening the animals through appropriate medication or dietary manipulation. Incorrect

support Exporter argument

D. Because it can only be contracted by genetically engineered fish, the Smith-Kreal disease was only discovered in 1994. Incorrect

irrelevant

E. While vitamin supplements improve general health of fish in ponds, they have been found to be inefficient in helping fish withstand the shock of pond drainage and transfer. Incorrect
