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?
Pre-thinking: The exporter's suggestion is weakened if any of the following is true:
1. Increased doses of vitamins are not available.
2. The immune systems is not strengthened even after giving the fish increased doses of vitamins.
3. A strengthened immune system of the fish doe not protect them against the viral attack.
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.
Option A is on the lines of point 3 mentioned above. Option A states that even if vitamins are are increased, it will not help the fish. This weakens the exporter's suggestion. Keep Option A.B. The drainage of a fish-breeding pond can be a stressful event that can result in the unnecessary death of many fish.
Option B does not relate to or talk about the viral attack to the fish. Hence it is irrelevant. Drop Option B.C. Diseases in fish can be prevented by strengthening the animals through appropriate medication or dietary manipulation.
Too generic. Passage talks about a specific cases. Drop Option C.D. Because it can only be contracted by genetically engineered fish, the Smith-Kreal disease was only discovered in 1994.
Irrelevant information. Drop Option D.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.
Same error as Option B. Drop Option E.IMO answer should be Option A. _________________
