Read the following article and select the best answer. Article: Recently, Danny Meyer, founder of the Shake Shack chain, announced that his restaurants will do away with tipping. He plans to pay his staff higher wages and pass the cost to customers by raising prices on menus. Is this a good idea? I'm sure Meyer's latest move will be a winner. The new model could work in Meyer's restaurants because he draws a particular type of customers who are there for a high-end experience. Besides, if the restaurants charge more for meals, they'll pay higher in taxes. As restaurants move to higher wages, the benefit costs will be higher, too. --Mel Robbins For a European, eating in an American restaurant is like attending a high school reunion. Tipping turns the whole process into a drawn-out experience where money is at the center stage. There are so many opportunities for embarrassment. So I think Danny Meyer's proposal will change it for the better. --Andre Spicer Danny Meyer is doing the right thing by stopping tipping. Eating out costs what it costs and workers are hard-working humans who deserve the stability of a wage. It may take a while to catch on, but we'll get there and it'll become the norm. --Kat Kinsman I've found that the practice of tipping has traditionally attracted millions of employees to our industry. The current tipping model still has strong support from diners and they are more than happy to reward good service. But it is vital that restaurants continue to have the freedom to choose what works best for their business and their employees. --Cicely Simpson Question: The four people's topic is focused on . - how diners feel in American restaurants - whether diners should be charged more - how restaurants can offer good service - whether restaurants should ban tipping
whether restaurants should ban tipping

Read the following article and select the best answer. Article: Let's face it -- you're going to get a lot of well-intentioned advice from friends, parents and grandparents about your sleep. Some of this advice is going to be just wrong. Myth 1: Sleeping late on the weekends will make up for lost sleep during the week. Fact: Getting less than the amount of sleep that you need night after night accumulates over time and starts to create a "sleep debt". And like all debts, eventually you need to pay the price. The problem with waiting until the weekend to meet sleep needs is that in the meantime, you are paying the price of being less alert, feeling more moody, thinking slower and having less stimulation. Myth 2: A boring teacher (or warm room, full stomach, etc.) can put teens to sleep. Fact: If you are getting enough sleep on a regular basis, there is no teacher, math book or reading assignment in the world boring enough to make you fall asleep in class. There are basically two things that make people sleepy -- not getting enough sleep and not getting good quality sleep. The environment kids are in, including the room temperature, light level and entertainment value, may unmask underlying sleepiness, but the environment does not cause it! So if you are dozing off in class, don't blame it on bad teaching. Myth 3: Teenagers can pull an all-nighter to study and still be ready for the big test in the morning. Fact: Teenagers are much better off studying less and getting a good night's sleep. Research clearly shows that the ability to concentrate and learn new information, as well as to work efficiently, declines sharply after being awake for 15-16 hours, and continues to bottom out the longer you stay up. Plus, if the big test is at 8:00 am, the problem gets even worse. That's because morning time typically represents a low energy point in the body's normal 24-hour circadian rhythm, especially in teenagers. Question: According to the passage, a student who is in a sleep debt _ . - thinks slower but more carefully - must make up for the lost sleep on the weekends - will become more interested in fancying - will become bad-tempered and upset
(Answer)
will become bad-tempered and upset

Read the following article and select the best answer. Article: Prolonging human life has increased the size of the human population. Many people alive today would have died of childhood diseases if they had been born 100 years ago. Because more people live longer, there are more people around at any given time. In fact, it is a decrease in death rates, not an increase in birthrates, that has led to the population explosion. Prolonging human life has also increased the dependency load. In all societies, people who are disabled or too young or too old to work are dependent on the rest of society to provide for them. In hunting and gathering cultures, old people who could not keep up might be left behind to die. In times of , infants might be allowed to die because they could not survive if their parents starved, where as if the parents survived they could have another child. In most contemporary societies, people feel a moral to keep people alive whether they can work or not. We have a great many people today who live past the age at which they want to work or are able to work; we also have rules which require people to retire at a certain age. Unless these people were able to save money for their retirement, somebody else must support them. In the United States many retired people live on social security checks which are so little that they must live in near poverty. Older people have more illnesses than young or middle-aged people; unless they have wealth or private or government insurance, they must often "go on welfare" if they have a serious illness. When older people become or too weak and ill to care for themselves, they create grave problems for their families. In the past and in some traditional cultures, they would be cared for at home until they died. Today, with most members of a household working or in school, there is often no one at home who can care for a sick or weak person. To meet , a great many nursing homes and hospitals have been built. These are often profit making organizations, although some are sponsored by religious and other nonprofit...
