Background: Chen Guangcheng (born 12 November 1971) is a Chinese civil rights activist who has worked on human rights issues in rural areas of the People's Republic of China. Blind from an early age and self-taught in the law, Chen is frequently described as a "barefoot lawyer" who advocates for women's rights, land rights, and the welfare of the poor. He is best known for accusing people of abuses in official family-planning practices, often involving claims of violence and forced abortions. In 2005, Chen gained international recognition for organising a landmark class-action lawsuit against authorities in Linyi, Shandong province, for the excessive enforcement of the one-child policy.
Context: Chen is the youngest of five brothers of a peasant family from the village of Dongshigu, Yinan County, Shandong Province, approximately 200 kilometres (120 mi) from the city of Jinan. When Chen was about six months old, he lost his sight due to a fever that destroyed his optical nerves. In an interview for the New York Review of Books, Chen said that although his family did not identify with an organized religion, his upbringing was informed by a "traditional belief in virtue that's present in Chinese culture--that might have some Buddhist content, but not necessarily that one believes in Buddhism." His village was poor, with many families living at a subsistence level. "When I went to school I'd be happy if I just got enough to eat," he recalled.  Chen's father worked as an instructor at a Communist Party school, earning the equivalent of about $60 annually. When Chen was a child, his father would read literary works aloud to him, and reportedly helped impart to his son an appreciation of the values of democracy and freedom. In 1991, Chen's father gave him a copy of "The Law Protecting the Disabled," which elaborated on the legal rights and protections in place for disabled persons in the PRC.  In 1989, at the age of 18, Chen began attending school as a grade one student at the Elementary School for the Blind in Linyi city. In 1994, he enrolled at the Qingdao High School for the Blind, where he studied until 1998. He had already begun developing an interest in law, and would often ask his brothers to read legal texts to him. He earned a position at the Nanjing University of Traditional Chinese Medicine in 1998 but because his family was poor, they had to borrow $340 to cover tuition costs. They still fell short of the required $400 and university authorities reportedly had to be pleaded with before allowing Chen to enroll. He studied in Nanjing from 1998 to 2001, specializing in acupuncture and massage--the only programs available to the blind. Chen also audited legal courses, gaining a sufficient understanding of the law to allow him to aid his fellow villagers when they sought his assistance. After graduation he returned to his home region and found a job as a masseur in the hospital of Yinan County.  Chen met his wife, Yuan Weijing, in 2001, after listening to a radio talk show. Yuan had called into the show to discuss her difficulties in landing a job after graduating from the foreign language department of Shandong's Chemistry Institute. Chen, who listened to the program, later contacted Yuan and relayed his own story of hardship as a blind man living on just 400 Yuan per year. Yuan was moved by the exchange, and later that year, she traveled to Chen's village to meet him. The couple eloped in 2003. Their son, Chen Kerui, was born later that year. In 2005 they had a second child--a daughter named Chen Kesi--in violation of China's one-child policy. Yuan, who had been working as an English teacher at the time of the marriage, left her job in 2003 in order to assist her husband in his legal work.

Problem: Background: Grace Brewster Murray Hopper (nee Murray; December 9, 1906 - January 1, 1992) was an American computer scientist and United States Navy rear admiral. One of the first programmers of the Harvard Mark I computer, she was a pioneer of computer programming who invented one of the first compiler related tools. She popularized the idea of machine-independent programming languages, which led to the development of COBOL, an early high-level programming language still in use today. Hopper had attempted to enlist in the Navy during World War II, but she was rejected by the military because she was 34 years of age and thus too old to enlist.
Context: Following her retirement from the Navy, she was hired as a senior consultant to Digital Equipment Corporation (DEC). Hopper was initially offered the job position by Rita Yavinsky, but she insisted on applying for the position at DEC, and going through the typical formal interview process. She also sent a letter to Yavinsky's boss explaining that she would be available on alternating Thursdays, receiving a high salary, and have access to an unlimited expense account if she were to be exhibited at their museum of computing as a pioneer. After the proposal from Hopper, she was hired as a full-time senior consultant. As part of her position, she would report to Yavinsky. In this position, Hopper represented the company at industry forums, serving on various industry committees, along with other obligations. She retained that position until her death at age 85 in 1992.  Hopper was a goodwill ambassador in her primary activity in this capacity. She lectured widely about the early days of computing, her career, and on efforts that computer vendors could take to make life easier for their users. She visited most of Digital's engineering facilities, where she generally received a standing ovation at the conclusion of her remarks.  She often recounted that during her service she was frequently asked by admirals and generals why satellite communication would take so long. So during many of her lectures, she illustrated a nanosecond using salvaged obsolete Bell System 25 pair telephone cable, cut it to 11.8  inch (30  cm) lengths, the distance that light travels in one nanosecond, and handed out the individual wires to her listeners. Although no longer a serving officer, she always wore her Navy full dress uniform to these lectures, which is allowed by US Navy uniform regulations.  The most important thing I've accomplished, other than building the compiler, is training young people. They come to me, you know, and say, 'Do you think we can do this?' I say, "Try it." And I back 'em up. They need that. I keep track of them as they get older and I stir 'em up at intervals so they don't forget to take chances.
Question: What did she do in this role?
Answer:
In this position, Hopper represented the company at industry forums, serving on various industry committees, along with other obligations.
