In the question below, a premise describing a situation is given. From the options, choose the statement that most weakens the conclusion provided in the premise. Premise: 'Quick-Dine' is a popular fast-food chain. Over the last four years, its customer satisfaction rating had been improving by 10% annually. To further boost this, the chain hired a new Operations Manager known for her expertise in streamlining kitchen efficiency. She implemented a new automated ordering system and reduced the number of staff members at the front counter to speed up the service. However, following these changes, the customer satisfaction growth rate dropped to just 2%. The board concluded that the new Operations Manager’s changes were the direct cause of the decline in satisfaction growth. Which of the following, if true, would WEAKEN the board's conclusion?

The Conclusion: The board blames the Operations Manager's internal changes (automation and reduced staff) for the dip in the growth of customer satisfaction. Analysis of Option B: If three major competitors opened nearby at the same time, customers now have more choices and may be more critical of 'Quick-Dine'. This external factor provides an alternative explanation for the drop in satisfaction growth that has nothing to do with the internal changes. By providing an "Alternative Cause," it weakens the link between the Manager's actions and the result. Evaluation of other options: * A relates to cost, not customer satisfaction. C is a background detail that doesn't explain the current 2% growth rate. D actually strengthens the idea that her changes were good (improved speed), making the dip in satisfaction even more confusing, but it doesn't offer an alternative reason for the dip. E explains where the staff went, but doesn't explain why the customers are less satisfied.
