After a competitor's influencer marketing campaign doubled their sales last quarter, our marketing director recommends increasing our budget for similar campaigns. She argues that since the competitor's product and campaign structure were nearly identical to ours, we can expect comparable results.
Which of the following, if true, would most call into question the marketing director's recommendation?
Social media advertising costs have risen by 15% since the competitor launched their campaign.
Industry surveys show that consumers are becoming increasingly skeptical of influencer endorsements.
The competitor's product had significantly fewer features than the company's current offering.
The competitor's campaign targeted a demographic with substantially higher disposable income than the company's customer base.
The competitor's campaign ran during a major sporting event that boosted visibility beyond typical levels.
After a consumer goods company reduced prices by 15% last quarter, its market share increased significantly. Company analysts concluded that the price reduction was responsible for attracting new customers who were previously deterred by the higher price.
Which of the following, if true, most undermines the explanation given for the change in consumer behavior?
The company's market research department had predicted that the price reduction would lead to increased sales.
Many consumers who switched brands cited dissatisfaction with the previous brand's customer service, not its price.
Surveys show that most consumers were unaware of any price changes in the market during last quarter.
The new pricing strategy was accompanied by a significant advertising campaign highlighting the product's quality.
Competitors also lowered their prices by 15% during the same period, maintaining identical relative price differences.
A company observed a surprising 40% increase in sales of its eco-friendly product last quarter, while sales of its conventional product remained flat. The company concluded this demonstrates growing consumer awareness of environmental issues.
Which of the following, if true, most seriously weakens the argument's explanation for the sales increase?
Sales of the conventional product increased by 15% in markets where the eco-friendly version was not available.
Many consumers who purchased the eco-friendly product did so only because it was heavily discounted.
Consumer surveys show that environmental concerns have become less important to shoppers over the past decade.
The eco-friendly product costs 10% more to manufacture than the conventional alternative.
The company increased its marketing budget for the eco-friendly product by 50% during the same period.
After seeing a 12% sales decline last quarter, a consumer goods company decided to launch an eco-friendly product line with sustainable packaging. Market research shows growing consumer interest in sustainability, so executives conclude this new line will reverse the sales decline.
Which of the following, if true, casts the most doubt on the argument's conclusion?
Government subsidies for sustainable packaging will be reduced by 50% in the coming fiscal year.
Over the past decade, products marketed as environmentally friendly have consistently underperformed in sales projections.
The company's main competitor has announced plans to introduce a similar eco-friendly product line next quarter.
Consumer surveys indicate that most shoppers prefer to buy products with minimal packaging regardless of price.
Production costs for eco-friendly packaging have risen by 15% this year due to supply chain disruptions.
The government has proposed new environmental regulations targeting industrial emissions. Officials argue that these regulations are justified because their projected economic costs to businesses are outweighed by their long-term health and environmental benefits, based on cost estimates from similar past regulations.
Which of the following, if true, would most seriously weaken the argument?
The environmental protection agency has recently increased its budget for enforcement of the new regulations.
The regulations include provisions for gradual implementation over a five-year period.
Several major corporations have already announced plans to pass the increased costs directly to consumers.
The compliance costs for similar regulations in neighboring countries were significantly higher than initially projected.
A recent study found that the targeted pollutants cause more health problems than previously believed.
