There appears a new housing platform which can detect the stress on electricity -- and the stress on the heart. "There is a growing population of elderly people, and there are statistics to show that more and more of them are going to live alone in the home," said Johann Siau, a senior lecturer at the University of Hertfordshire in the U.K., who was leading the InterHome project. The system was originally designed to provide remote access to a house so owners could be more energy-efficient. In a small type of the system, set-in controller devices connect securely to the Internet. The owner can then monitor them with a cell phone or computer. User feedback helps the system adapt to routines, saving on electricity. While thinking about responding to user behavior and an increasingly elderly population, the researchers decided to add wristband technology that senses important organs of the body such as body temperature and pulse, Siau said. "If someone were to fall, it would detect the fall and it would immediately start the monitor of the pulse to see if the person has gone into shock ," he said. The wristband communicates with the home system wirelessly. Data from the band can be securely transmitted to the home network and accessed by authorized users. "We're working on trying to reduce it to a level where it could potentially be a wrist-sized product," Siau said. But he warned that the technology presented new challenges. "When you start using that on a larger scale, you have issues of privacy or security," he said. Siau said the InterHome home system isn't intended to invade privacy. "We're thinking about the elderly people who are living alone with no one looking after them," he said. "Hopefully this will be able to decrease some concerns and possibly save a few lives." Question: What challenges will the new technology bring according to Siau? Options: A: The wristband can be large and expensive. B: The wristband will get false information of a person. C: It will not be used in the proper way. D: It will bring inconvenience to the old people.

Q: Read the article and select the best answer. Article: The Sewol ferry was carrying 476 people, most of whom were students from a high school near Seoul, when it sank off South Korea's southern coast on April 16. Only 174 survived, including 22 of the 29 crew members. The sinking left more than 260 people dead with about 40 others still missing. On Tuesday, one ordinary diver died at a hospital, government spokesman Ko Myung-seok said. He is the first death among divers organized following the ferry's sinking, according to the coast guard. The 53-year-old diver was pulled to the surface by his teammates after losing communication about five minutes after he began underwater searches, Ko said. It was his first search attempt, Ko added. Despite his death, divers are continuing their searches for the remaining missing people. Ko said that divers had searched all those 64 areas at least once and plan to visit them again to look for more victims. Darkness, floating rubbish, bodies, and cabins on board have made the search difficult, and divers entered the last three unopened areas on Monday night, Ko said. Investigators have made their first arrests of people who were not on board the Sewol when it sank. The three people arrested on Friday and Sunday are accused of failure to handle of cargo on the ferry well. In all, 19 people have been arrested in the investigation , 15 of whom were crew members accused of abandoning passengers. A leader was arrested on suspicion of malpractice related to company finances. Improper stowage and overloading of cargo is suspected as a possible reason why the ferry sank. The ferry was carrying about 3,608 tons of cargo, more than three times what it could safely carry. A ferry loaded too heavily could lose its balance making even a small turn. The sinking has caused a national sadness. On Sunday 1.1 million people paid respects at 131 memorial sites around the nation, according to a governmental funeral support committee set up for the ferry victims. Monday was a holiday for Children's Day, but various events were canceled or put... Question: According to the investigation, the main causes of the ferry's sinking are _ .

Allow me to suggest some tips that may help you stick to your decisions creating long- lasting positive change in your life. Telling other people about your plan can help in many ways. First, it is always easier to stick to a decision when you have other people supporting you. Your friends are less likely to tempt you with whatever it is you are trying to control if they know that you made a decision about it. Telling other people about your decision is also helpful in that it keeps us to the pressure on you to try and stick to you plan of action. Choose a measurable and specific decision. Instead of deciding to "look better" or "have a better relationship with so and so", choose a more definable decision. Deciding to "eat a vegetable every day" or "go out for coffee once a week with John" is much easier to track and assess than a general decision to "be a better person". Build a reward system. Connected to the last tip of choosing a measurable and specific decision is that when you do accomplish this specific behavior you decided to do, give yourself small rewards along the process. For example, for every week of healthy eating treat yourself with something special. Creative visual aids. A colleague of mine decided one year for his New Year's decision to be more frugal.
