四、閱讀測驗【請依照段落上下文意，選出最適當的答案】        Facebook plans to hire more remote workers in areas where the company doesn’t have an office and let somecurrent employees work from home permanently if they’d like to. Chief Executive Officer Mark Zuckerberg saidthe company plans to open up remote hiring starting immediately with the U.S., particularly for engineering talent.Based on internal employee surveys, he believes remote workers could make up as much as 50% of Facebook’sworkforce in the next 5 to 10 years. Facebook is the latest, and largest, technology company to announce a full orpartial move to more permanent remote work amid the COVID-19 pandemic. Twitter Inc. and Square Inc., both runby CEO Jack Dorsey, have announced that their employees can work from home permanently if they’d like to.Canadian e-commerce company Shopify Inc. also said it will allow its 5,000 staff to work from home indefinitely.        It’s a trend that could significantly change Silicon Valley and the San Francisco Bay Area, which for decadeshas been the center for high-paying technology jobs. Many of the world’s most valuable companies, includingFacebook, Apple and Google are headquartered just south of San Francisco, which has made the surrounding areaone of the wealthiest and most expensive in the world.        Facebook employees who wish to work remotely, and are approved to do so, will be paid based on their newlocation, Zuckerberg added. That means employees who move to areas with a lower cost of living than the Bay Areawould likely take a pay cut.
