Problem: Given the question: Write a multi-choice question for the following article: Article: It was not until the eighteenth and nineteenth centuries that exploration of the _ world began on a large scale. European middle classes took great interest in collecting new plants. This attraction to exotic plants grew as European nations moved into other parts of the world such as Asia andprefix = st1 /Australia. Brave young men took the opportunity of going on botanical expeditions even though they were to be faced with deadly disease, near-starvation, severe environments and conflicts with the local people. Sir Joseph Banks was among the brave. In 1760, he collected vast quantities of plants in what is now known as Australia. None of these plants had been recorded by Europeans before. However, Banks was not able to bring those plants back to Europe and let them grow in his homeland because keeping plants alive during long land or sea voyages was a great challenge at that time. Large numbers of seeds failed to grow after long sea voyage or trips across land far away from Europe. In 1833 the invention of the Wardian case, a tightly sealed portable glass container, made it possible for two cases of British plants to survive the six-month journey to Australia. And the return trip in 1835 with Australian species lasted eight months at sea, all the species successfully arriving inLondon. China was a land the earliest European plant collectors would explore from time to time. . Not only did Europeans collect large numbers of plants to grow in Western gardens, but also they were very excited with the knowledge that Chinahad a vast variety of plants. A British man called Robert Fortune developed his fluency in Chinese and was disguised as a Chinese man so that he could travel aroundChinaunnoticed. He managed to ship 20,000 tea plants from Shanghai toIndia, where a successful tea industry was established.

Problem: Given the question: Write a multi-choice question for the following article: Article: Japanese workers who run secretly out of the office and spend their afternoons hanging around coffee shops may soon be caught out by their bosses. A new cellphonebased tracking device from Hitachi can show, on an employer's computer screen, not only the whereabouts of their workers but also whether they are standing, walking, running--or have fallen over. The system, called Partout, was originally developed as a monitoring device for the families of people with dementia, who may wander off and need to be located. "It's estimated that the number of elderly people with symptoms of dementia will reach 1.5 million in Japan next year," says Hitachi's Keisaku Shibatani. But the high cost of the system--early prices are around PS27,000--has put it out of reach of most families. Indeed, companies with large sales forces and police departments who want to track officers on dangerous patrol duties are interested in the system. Partout uses a multifunction location sensing unit that tracks users through global positioning satellites. The user's body motion is determined by an accelerometer inside the sensing unit: no movement means the subject has stopped, slow movement means they are walking, fast movement means they are running, and strong and unexpectedly sudden movement means the user may have fallen. The date is relayed through the user's cell phone to computer, which displays their position on a map. Graphics record the motion or position of the subject's body.

Problem: Given the question: Write a multi-choice question for the following article: Article: Older people with hearing loss may suffer faster rates of mental decline. People who have hearing trouble suffered meaningful impairments in memory, attention and learning about three years earlier than people with normal hearing, a study published online January 21 in JAMA Internal Medicine reveals. The finding supports the idea that hearing loss can have serious consequences for the brain,says Patricia Tun of Brandeis University in Waltham,Mass., who studies aging. "I'm hoping it will be a real wake-up call in terms of realizing the importance of hearing. " Compared with other senses, hearing is often overlooked, Tun says. "We are made to interact with language and to listen to each other, and it can have damaging effects if we don't." Frank Lin of Johns Hopkins School of Medicine and colleagues tested the hearing of 1,984 older adults. Most of the participants, who averaged 77 years old, showed some hearing loss -- 1,162 volunteers had trouble hearing noises of less than 25 decibels, comparable to a whisper or rustling leaves. The volunteers; deficits reflect the hearing loss in the general population: Over half of people older than 70 have trouble hearing. Over the next six years, these participants underwent mental evaluations that measured factors such as short-term memory, attention and the ability to quickly match numbers to symbols. Everybody got worse at the tasks as time wore on, but people with hearing loss had an especially sharp decline, the team found. On average, a substantial drop in performance would come about three years earlier to people with hearing loss. Lin cautions that the study has found an association between hearing loss and mental abilities; the researchers can't conclude that hearing loss directly causes the decline. Yet more and more studies are turning up ways that diminished hearing could damage the brain. A person who can't hear well might avoid social situations, and isolation is known to be bad for the brain. "You gradually become more socially withdrawn, " Lin says....
