A new report says an estimated 6.9 million children worldwide died before their fifth birthday. That compares to about twelve million in1990. The report says child _ rates have fallen in all areas. It says the number of deaths is down by at least 50 percent in eastern, western and southeastern Asia. The number also fell in North Africa, Latin America and the Caribbean. Ties Boerma is head of the WHO's Department of Health Statistics and Informatics. He says most child deaths happen in just a few areas. TIES BOERMA: "Sub-Saharan Africa and southern Asia face the greatest challenges in child survival. More than eighty percent of child deaths in the world occur in these two regions. About half of child deaths occur in just five countries--India, which actually takes twenty-four percent of the global total; Nigeria, eleven percent; the Democratic Republic of Congo, seven percent; Pakistan, five percent and China, four percent of under-five deaths in the world." Ties Boerma notes that, in developed countries, one child in one hundred fifty-two dies before his or her fifth birthday. But south of the Sahara Desert, one out of nine children dies before the age of five. In Asia, the mortality rate is one in sixteen. The report lists the top five causes of death among children under five worldwide. They are pneumonia, diarrhea, malaria and problems both before and during birth. Tessa Wardlaw is with the U-N Children's Fund. She is pleased with the progress being made in Sub-Saharan Africa. The area has the highest under-five mortality rate in the world. But she says the rate of decline in child deaths has more than doubled in Africa. TESSA WARDLAW: "We welcome the widespread progress in child survival, but we importantly want to stress that there's a lot of work that remains to be done. There's unfinished business and the fact is that today on average, around nineteen thousand children are still dying every day from... Question: Since 1990, the number of the children who died before 5 in the world has dropped by about _ . - 6,900,000 - 12,000,000 - 1,200,000 - 5,100,000

Article: With the press of a button, a person with severe spinal cord injuiy is able to walk again, thanks to the Walking Assistive Exoskeleton Robot (WAER). Powered suits that could help paralyzed people walk and others lift and carry heavy loads with ease have been a dream since late 19th century. But they can realize their dreams in the 21st century. The 20-kilogram robot has four battery-powered motors that can run for up to three hours. Inventor Wu Chenghua, from Taiwan's Industrial Technology Research Institute, says it has successfully been in tests on 12 patients. "We have learned from our research process that patients whose injuries are below the fourth chest joint are able to use our robot to stand, walk and sit down," he said. Since walking contributes to muscle exercise, Wu says patients receive some additional benefits. "In the clinical process, we would check their bone mineral density ,and we found that the bone mineral densities of these patients had been improved." he said. Wu says his exoskeleton may be available for consumers by 2018. Meanwhile, baggage handlers at Tokyo's Haneda Airport will soon start testing a similar robot, developed by the Japanese firm Cyberdyne. The battery-powered robot weighs only 3 lift a heavy object, the machine monitors the movemen",says Yoshiyuki Sankai, the developer and CEO of Cyberdyne. "This robot suit monitors the signal from the human nerve system to support the waist's movement," Sankai said, "It self-adjusts the level support to reduce the load on the human waist, light and smart. We believe that it will change the life of paralyzed people in many ways and have a promising future." Question: What can we learn about the invention of Wu Chenghua from the passage? - It weighs 3 kilograms and can run for up to three hours. - It will soon get tested at Tokyo's Haneda Airport. - It may be put into use for consumers by the year 2028. - It can be used by patients with injuries below the fourth chest joint.
It can be used by patients with injuries below the fourth chest joint.

Article: Marjorie Baer used to joke about her retirement plans.She wasn't married and had no kids, but she didn't intend to be alone--she and all her single friends would move into a fictional home she called Casa de Biddies.Instead, Baer developed terminal brain cancer when she was 52.But just as she'd hoped, her friends and family provided her with love and care to the end. Ballance was only the first of Baer's friends who became her unofficial caregivers.With her brother Phil Baer from Los Angeles, they worked out a system to watch over their friend and allow her to keep some of the privacy and independence she cherished. Baer's good friend Ruth Henrich took Baer to doctors' appointments and helped her deal with all the aspects of life --answering machines, TV controls, and even phone numbers.After Henrich sent out an e-mail request, a group of volunteers signed up to ferry Baer back and forth to radiation therapy .Others in Baer's circle offered up particular talents: A nurse friend helped Baer figure out how to get what she was due from Social Security and her disability insurance; a lawyer pal helped Baer with her will; a partner who was an accountant took over her bills when she could no longer manage them."There was this odd sense that the right person always showed up," says Ballance.Their arrangement worked remarkably well. Unmarried women are one of the fastest-growing groups in America; experts are concerned about how care-giving will be managed for them as they age.If the experience of Baer's friends is a guide, _ .It's already making it possible to create communities of caregivers who may have only one thing in common: the person who needs their help.On personal "care pages" set up through services such as Lotsa Helping Hands, friends and family members can post a list of tasks that need to be done, volunteer to do them, and keep updated on the person's condition.As Baer's cancer progressed, for example, her friends set up a page on Yahoo! where people could sign up to deliver meals or do errands... Question: Who helped Marjorie Baer get her disability insurance? - Ruth Henrich. - Her brother. - A nurse friend. - Ballance.
A nurse friend.
