Fish Breeder: A Rare Illness Known As Smith-Kreal Disease is Spreading GMAT Critical Reasoning

Question: 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?

1. 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.
2. The drainage of a fish-breeding pond can be a stressful event that can result in the unnecessary death of many fish.
3. Diseases in fish can be prevented by strengthening the animals through appropriate medication or dietary manipulation.
4. Because it can only be contracted by genetically engineered fish, the Smith-Kreal disease was only discovered in 1994.
5. 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.

“Fish Breeder: A Rare Illness Known As Smith-Kreal Disease GMAT Critical Reasoning”- is a GMAT critical reasoning topic. This GMAT critical question includes sets of five options stating different arguments. The candidates must go through the passage and must select the option that suits well with the passage. GMAT critical reasoning is designed to measure the rational skills and efficiency of the candidates. In order to solve the question, a candidate needs to search for a shred of evidence that would weaken the statement or can have rational flaws in the argument. The GMAT critical reasoning section consists of 36 MCQ questions and the candidates get 65 minutes to answer those questions.

Answer: A
Explanation:

The critical reasoning section of the GMAT evaluates a candidate's capacity for critical and analytical thought. The candidate must use deduction and reasoning to formulate a logical response. The best way to choose the proper answer is to carefully consider each option separately. Analyzing each option will help the candidate to understand it thoroughly. Thus each option can be determined whether it has the right elements or statement to be the right answer based on the subject of the question. The question asks for the answer that would undermine the argument given by the exporter.

Option A: Correct

This states that Erwin Smith and Jason Kreal discovered and studied the Smith-Kreal disease. It is so aggressive that it can overcome any type or degree of biological defense a fish may have. This suggests that no medication will help to reduce Smith-Kreal disease. This insight will weaken the ideology of the exporter.

Option B: Incorrect

This explains that a fish breeding pond's drainage can be a stressful situation that causes unnecessarily many fish deaths. This revelation weakens the fish breeder's case rather than the exporter's.

Option C: Incorrect

This states that Fish diseases can be avoided by bolstering the animals with the right drugs or dietary changes. Instead of undermining the exporter case, this explanation supports it.

Option D: Incorrect

The Smith-Kreal disease was only identified in 1994 and is only transmitted by genetically modified fish. This is valuable information, but is not relevant to the subject of the question.

Option E: Incorrect

This states that vitamin supplements have been found to be ineffective at helping fish withstand the shock of pond drainage and transfer. This is stated despite the fact that they improve fish in ponds' overall health. The same reason as the second option.

Therefore the first option is the right answer.
