[单选题]Passage 2For Chen Hua，28，an automobile engineer in Shanghai，reading out English text aloud after taking pronunciation lessons on a mobile app has become an evening routine. Chen might skip dinner，but wouldn't trade even one language class delivered by the app for anything.Not having been using English much since leaving college，Chen feels the pressure to pick it up using spare time. The"pressure"arises from a constant fear of being left behind as English-proficient peers appear to get ahead. Academic circles refer to this as "middle-class anxiety"，which is grasping some sections of China's population.In a report released by leading online recruiter Zhaopin in January，one-fourth of surveyed white-collar workers said they feel more stressed than inspired，citing reasons from unstable paychecks to gloomy career prospects. Most important of all many people worry that the worth and utility of their knowledge and qualifications could erode due to thriving technological progress，globalism and entrepreneurship."Intensified peer pressure, especially at workplaces, is one factor that fuels our business,"said Wang Yi, CEO of Liulishuo, an English-learning app that Chen uses every day. Wang,a Princeton computer science graduate and former product manager at Google Inc, launched the app over five years ago with the intention to disrupt China's hidebound brick-and-mortar language schools.Liulishuo-it is Chinese for"speaking fluently"-brings social media and gaming elements to the genre. Wang said that unlike pre-school or K12 education, the adult-learning market is characterized by an inherent desire for self-improvement. Students of online adult education courses feel the fee is money well spent.To personalize offerings, Liulishuo has introduced big data and algorithms to quantify multiple dimensions of speech, as well as automatically tailor courses so that the courses could walk a fine line between challenging the students and discouraging them to the extent that they quit learning.Actually, this is not just confined to language courses. China's growing learners have shown they will spend time on the right educational programs.The text is mainly developed by________.
