Which of the following regions in the world will witness the sharpest drop in life expectancy?

16. A data shows that the global AIDS pandemic will cause a sharp drop in life expectancy in dozens of countries, in some cases, declines of three decades. Several nations are losing a century’s progress in extending the length of life. Nations in many parts of the world, 51 in all, are suffering declining life expectancies because of an increasing prevalence of HIV infection. The increase is occurring in Asia, Latin America, and the Caribbean, but is greatest in sub-Saharan Africa, a region with only 10% of the world’s population but 70% of the world’s HIV infections. Seven African countries have life expectancies of less than 40 years.
17. Charles Schulz brought happiness to millions of people. He was born in 1922 in Minneapolis, Minnesota. His father was a barber who cut men’s hair. When Charles was five, his teacher told him: " Some day, Charles, you’re going to be an artist. " But he sometimes had trouble with his school work. In high school, he was poor at sports. He was afraid to ask a girl to go out with him. His high school publication rejected some of his drawings he hoped it would publish. At age seventeen, Charles began studying art. He took a class by mail from a Minnesota art school. This was the only art education he ever had.
18. A credit card that only works when it hears its owner’s voice has been developed by US scientists. Researchers hope that the device, which comes with the built-in voice-recognition chip, and microphone, will be a weapon in the battle against credit card fraud. Even if thieves know a card’s password and personal identification number, they’ll still have to copy the owner’s voice accurately. The trial card was created by scientists at "B-card" , in California. The first version is three times as thick as a normal credit card, but researchers believe smaller chips will allow the card to slim down to a more conventional size. The card is apparently the first to put voice-recognition chip, microphone, speaker, and battery into a credit card.
19. Afghan Interior Ministry spokesman Zamary Bashary tells VOA that a rocket hit the road between a hospital and the Serena Hotel, a popular residence in Kabul for visiting foreigners. " The police have been dispatched to the area to investigate and verify from which side the rocket had been launched," he said. Militants have targeted the heavily guarded Serena Hotel in the past. The hotel is located in the centre of Kabul, near the presidential palace, government ministries and embassies.
20. "One in ten young people claim to have had no career advice during their education. Around two-thirds haven’t decided on the career by the time they leave school," says the YouGov Poll for recruitment consultancy Harvin Nash. "Most rely on friends, but many are turning to the Internet for advice instead, and a career service needs to embrace this," say experts. The knock-on effect of confusing and unhelpful career advice is that young people aren’t making the best use of their skills, and industry is losing out on the most talented candidates. Harvin Nash’s chief Albert Alley said, " Without direction and advice, not only are young people missing out on potential career opportunities themselves, but businesses, too, could be missing out on the next generation of skills they need to compete.
