A manager is hoping to reach a certain target for camera sales in his store, which sells between 10 and 20 cameras a week. Typically, most cameras sold in any week are the less expensive economy models, and his store has sold relatively fewer of the more expensive, high-end cameras. The manager realizes that if, on average, three more cameras sold each week were high-end instead of economy models, the store would reach its target in sales. The manager prepares a detailed information sheet for the sales associates, outlining the numerous advantages of the high-end cameras over the economy cameras, and provides each sales associate with a portfolio of contrasting photos of the same images, showing the clearly superior image quality of the high-end cameras. Which of the following, if true, would provide most support for the prediction that the detailed information sheet and photo portfolio given to sales associates will have its intended effect of allowing the store to reach its target in sales?
【选项】The only reason many customers buy the economy cameras is that they do not appreciate that the high-end cameras are significantly better.
