题目

阅读理解 A study from 2010 said that raising prices by 1%without losing sales can increase profits by 8. 7%on average. Getting the prices right can be difficult. Set them too high and you lose customers; set them too low and you leave money on the table. To make more money, shopkeepers have been turning to price-optimization（优化） systems that predict how customers will respond to price changes. These systems are becoming cleverer thanks to advances in artificial intelligence （AI）. While older systems used historical sales data to estimate（估计） price sensitivity for individual goods, the latest AI-powered systems can find relationships between multiple goods. These AI-powered systems use big data to estimate price sensitivity —how much demand increases as the price falls or how much demand decreases as the price goes up —for thousands of products. Price-sensitive（价格敏感的） goods can then be discounted and price-insensitive ones marked up. All this makes pricing systems "much more three-dimensional", observes Chad Yoes, the pricing official at Walmart, a supermarket. In February, Starbucks, a chain of coffee shops, expressed pride in its use of AI to price products" on an ongoing basis". US Foods, a food company, says its pricing system can promote sales and profits. Price-optimization may make prices change more. "Shopkeepers are pricing faster today than they ever have before, "says Matt Pavich of Revionics, a pricing-software firm. That is especially true in the fast-moving world of e-commerce. But even Walmart changes the prices of many items in its stores 2-4 times a year, says Mr Yoes, up from once or twice a few years ago. Sysco, a food company, says the AI-powered system allows it to lower prices on" key value items" and raise prices on other products. It can thus increase profits by expanding sales while maintaining profits. That keeps investors content and shoppers sweet. （1） What can be learned from the first paragraph? A .
