I'm taking a test and have to guess the right answer to the question after the article. Article: Smart home applications can share all kinds of helpful information with homeowners. 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: The system was first designed for a house owner to _ . Options: A: keep watch on his house B: keep his house safe C: monitor the elderly people inside D: save electricity

I'm taking a test and have to guess the right answer to the question after the article. Article: Studying abroad will shape you in various ways. You will learn things you never would have if you had stayed home. When you are young and unattached, you should travel. Besides, you just might save a large sum of money. College is expensive in the United States. It's cheap or free in other countries even for foreigners, so why not get out of here and come back smarter? More and more American students are currently studying at German colleges. That number has increased 20% over the last three years. Living costs are about $7,000 a year, which is even lower than in other European countries. Germany encourages international students. They create a multicultural landscape that benefits German students as well. According to a new report, Germany is home to six of the world's 100 best universities.

I'm taking a test and have to guess the right answer to the question after the article. Article: If you ask someone why he or she wears clothes, the answer will probably be "to keep warm and to cover my body". These are the basic reasons why clothes are worn, but people also want to look attractive and appear successful to others. If people only wore clothes for warmth and to cover their bodies, most clothes would be simple and cheap. In most Western countries, however, clothes are sometimes very expensive. The main reason for this is not the cost of the cloth or the cost of making the clothes. The clothes are expensive because of fashion . Successful businessmen, for example, often wear very expensive suits, shirts and ties. Sometimes they pay thousands of dollars for a suit and hundreds of dollars for a tie. It's just a suit and a tie but they pay these prices because of the famous name of the designer. A suit costing much less would be just as warm and would cover the wearer's body just as well. Fashion is always changing, which means those who want to be fashionable have to buy new clothes every few months, even if last month's clothes have only been worn once or twice. Some people have wardrobes full of clothes that have hardly been worn but are no longer in fashion. Being fashionable, therefore, can be a very expensive pastime ! Question: The main reason why clothes are sometimes very expensive is that _ . Options: A: one has to buy new clothes B: these clothes are in fashion C: the cost of the cloth is high D: making clothes costs much
