Read the following article and select the best answer. Article: The term "Industry 4.0" refers to the fourth industrial revolution. The first industrial revolution was the production of goods with machines like steam engines, which was followed by the second industrial revolution that introduced mass production with the help of electric power, followed by the digital revolution --the use of electronics and IT in production. Industry 4.0 is a high-tech project, which promotes the computerization of manufacturing . The basic principle of Industry 4.0 is that by connecting machines, work pieces and systems, we are creating intelligent networks along the entire value chain that can control each other automatically. The goal is the Smart Factory, which adapts well and uses resources efficiently as well as linking customers and business partners with great intelligence. Technological basis are the Internet systems and advanced factories. Experts believe that Industry 4.0 could be a reality in about 10 to 20 years. So, what effects does this change have on the classic manufacturing? According to an expert, "it is highly likely that the world of production will become more and more networked until everything is connected with everything else." Networks and processes have so far been limited to one factory. But in the time of Industry 4.0, the boundaries of individual factories will most likely no longer exist. Instead, they will be lifted in order to inter-connect multiple factories or even geographical regions. How is an Industry 4.0 factory different from a today's factory? In current industry environment, providing high-end quality service or product with the least cost is the key to success. Factories are trying to increase their profit as much as possible. In the time of Industry 4.0, various data sources are available to provide worthwhile information about different aspects of the factory. Using data for understanding the current condition and checking faults and failures is a natural thing. _ will enable these connected systems to manage themselves independently, work... Question: Industry 4.0 will probably result in _ in the world of manufacturing. - production limited to an individual factory - everything connected with everything else - networks and processes no longer existing - classic factories stopping their competition
everything connected with everything else

(Question)
Read the following article and select the best answer. Article: Randy Grim brought home his first stray dog when he was only 5 years old. The fear that he saw in the eyes of that first dog-eventually replaced by gratitude and love-moved Grim so deeply that even at that young age he knew he had found his life's work. In 1998, Grim formed a nonprofit group called Stray Rescue. The group's goal: to save as many of St. Louis's stray dogs as possible. Today, Grim heads up an organization with a $3 million annual budget, a staff of more than 50 paid workers, thousands of volunteers, and a well-equipped shelter that houses as many as 200 dogs. The money that supports Stray Rescue has been raised through donations and through the force of Grim's outspoken advocacy . A man who sees himself as shy is anything but that when it comes to speaking out for dogs. The impact has been significant. While there are no good estimates as to the number of stray dogs on the streets of St. Louis, today 40% more dogs are being picked up off the streets than just two years ago, about 98% are now adopted into homes. Stray Rescue also funds a massive education campaign. The group's bill-boards advocating adoption and neutering of dogs are everywhere, as are brochures informing the public of free medical care for dogs and volunteer opportunities at Stray Rescue. "The whole landscape has changed,"says Pam Walker, St. Louis city health director. Since Grim's involvement, she says, St. Louis has become a model for good practices in the area. Officials elsewhere sometimes ask how St. Louis deals with its dog problems. Walker says,"My answer is:We have Randy Grim." Grim says he is delighted at the way the city has responded. Many St. Louis citizens"were already there,"he says, in terms of concern for dogs. "I'm really proud of my city." Question: We can infer from the text that _ . - Stray Rescue promises to be the most famous - Grim has changed the whole city of St. Louis - most Americans are unwilling to solve dog problems - the number of stray dogs in St. Louis is reducing
(Answer)
the number of stray dogs in St. Louis is reducing

Ques:Read the following article and select the best answer. Article: Dear Mr./Ms, I would like to suggest that the starting time be changed at our school. Classes at Sebastian Valley Middle School simply start too early in the morning. Getting eight to nine hours of sleep each night is almost impossible when classes begin at 7:30 am. In order to shower, dress, get organized, eat a quick breakfast, and meet the school bus by 6:45, I would have to get up at 5:45. Early in the morning, students are too sleepy to learn well. Without enough sleep, young people cannot think clearly or enjoy learning. According to a report called "Are Students getting Enough Sleep?" From Sebastian Valley Times, "Sleepiness disturbs concentration, reduces short-term memory, and causes bad feelings." Researchers have learned that teens normally fall asleep and wake up later than adults. Teens who stay up late at night have trouble getting up early in the morning. Studies show that some schools have already adjusted school hours to better match the teen sleep cycle , as a result, students in these school are learning better on the new schedule . Some of my classmates argue that starting school an hour later will prevent them from taking part in after-school athletic programs. A solution would be to carry out these programs before school instead of after school. The students who are involved in sports and clubs would continue to arrive at the usual time. The rest of the student body could get a little more sleep and arrive an hour later. Teens usually have a later sleep cycle, and learn and behave better when rested. So I would like to suggest that we have a meeting to discuss the problem and listen to all the students' voice. Thank you for considering this request ! Question: In Tom's opinion, classes should begin at _ . - 6:45 - 7;30 - 8:00 - 8:30

Ans:
8:30
