单选题 Questions 6-10 are based on the following passage Passage 2 How an E-Commerce Platform Redefined Advertising Transparency ShopEase, a gigantic e-commerce platform, faced a crisis: consumers were losing trust in its ads, which were often vague about product quality and pricing. Many shoppers described the platform's "deals" as fuzzy, and its reputation for hidden fees became entrenched—hurting its ability to compete with smaller, more transparent rivals. To fix this, ShopEase launched an advertising revolution focused on clarity. The platform's savvy leaders made a fundamental change: all ads now include detailed product specs, real customer reviews, and breakdowns of discretionary fees. They also created a "Transparency Hub" where users can track how ads are distributed—from social media posts to email catalogs. This wasn't just a tactical move; it was part of a larger vision to make ShopEase synonymous with trust, not deception. While some subsidiaries initially resisted (worried the scrutiny would reveal flaws), the strategy worked. Exposure to ShopEase's ads increased by 40%, and customer motivation to purchase rose as doubts diminished. Even prominent influencers, who once avoided the platform, now promote its hoodies and electronics—calling ShopEase a "shopper's paradise." Though competition in e-commerce continues to intensify, ShopEase's commitment to transparency has turned its advertising from a weakness into a strength.
