To evaluate the claims made in the argument, let's break down the argument and examine the relevance of each question.
Argument Analysis:
Premise 1: A rare type of bacteria has killed off many tuna fish in North America.
Premise 2: Fishing boats have had very meager catches of tuna this year.
Premise 3: As a result, the wholesale price of tuna meat has increased significantly.
Conclusion: Therefore, the retail price of tuna-based cat food is certain to increase within six months.
The conclusion is drawn based on the assumption that an increase in the wholesale price of tuna meat will lead to an increase in the retail price of tuna-based cat food. To evaluate this claim, we need to consider factors that could affect the retail price of tuna-based cat food.
Evaluation of Each Question:
A. Can the bacteria be eliminated within the next six months?
This question is relevant because if the bacteria can be eliminated, tuna populations might recover, potentially reducing the wholesale price of tuna meat and impacting the retail price of cat food.
B. Are consumers willing to spend more for tuna-based cat food?
This question addresses demand elasticity. If consumers are not willing to spend more, retailers might absorb some of the increased costs instead of passing them entirely to consumers. Thus, this is relevant to the conclusion.
C. Has the price of cat food remained steady during other periods of poor tuna catches?
This question is highly relevant because it provides historical context. If retail prices have remained steady during past tuna shortages, it could indicate that other factors might mitigate the impact on retail prices.D. What percentage of tuna in North America were affected by the bacteria?
This question helps gauge the extent of the impact on tuna supply. If only a small percentage is affected, the impact on wholesale prices and subsequently retail prices might be less significant. This is relevant to understanding the severity of the situation.
E. Have the prices of other ingredients in tuna-based cat food decreased recently?
This question is relevant because if the prices of other ingredients have decreased, it might offset the increased cost of tuna meat, potentially preventing a rise in the retail price of the cat food.
Most Relevant Question:
While all the questions provide some relevant information, C (Has the price of cat food remained steady during other periods of poor tuna catches?) is particularly relevant. This question directly addresses historical pricing behavior, which is crucial in evaluating whether an increase in wholesale tuna prices will necessarily lead to a rise in the retail price of tuna-based cat food.Thus, the best answer is:
C.
