In a recent article about music's role in restaurant design, author Mark Brandau details the different ways sound influences sales. Here are a few "notes" to keep in mind the next time you need to pick a restaurant: It's someone's job to design playlists. Restaurant owners hire experts to build music playlists for different times of the day. A restaurant owner says, "Lively songs encourage quick dining and faster table turns at meal time." What you hear at lunch won't be what you hear at dinner. And what you hear after dinner will be something totally different. If a restaurant wants to increase late-night sales, music is very important to creating the right atmosphere. Music builds brands . Nick Vojnovic, president of Little Greek, had been in the business for 20 years. He began to realize how important music is to the restaurant experience after listening to a manager from The Cheesecake Factory speak about using music to develop brand identity. Where have you heard that before? Restaurants may be using the same music providers. Ambiance Radio provides playlists for Little Greek in Florida, and also Schlotzsky's and Union Square Cafe in New York City. Vojnovic, who started his business at Chili's, pointed out that years ago, background music was changed only once per quarter. Music helps restaurants choose diners. Brandau explains that some restaurants would like to turn up the music, not to bother certain groups of customers, but to stay true to their main diners. If college kids are a restaurant's main diners, the restaurant will surely play music that makes older people feel uninvited. Question: The passage mainly discusses the relationship between music and _ . Options: A: diners B: restaurant sales C: eating habits D: menus

Read the article and select the best answer. Article: Seeking to find happiness through a job before you find happiness on a personal level is like trying to stand on stilts on quicksand. That's how Anahita Moghaddam feels about it, anyway. She believes it is our "primary responsibility" to cultivate love and happiness within ourselves, first and foremost. Moghaddam says that if you only look to your professional achievements to keep your sense of purpose and well-being going, a sense of emptiness or desperation can't almost be avoided. You and your brain are more flexible than you think. The brain changes and grows depending on what it interacts with. Positive thoughts will give support to neuron pathways for the feeling of joy; negative thoughts will make neuron pathways for feelings of sadness stronger. "The number of possible combinations of neurons that fire and wire together is 10 to the millionth power in your nervous system. In comparison, the number of atoms in our entire universe is estimated to be around 10 to the 80th power. If we are 10 to the millionth power, that makes us almost infinite. So what are we? Who are we? And what can we do with this?" she says. Unfortunately, human brains have several biological tendencies to negative thoughts and feelings. First, human brains can identify and avoid threats. Often, that means that other humans instinctively register as competition, instead of teammates or comrades. Second, we're biologically likely to remember a single negative incident more than multiple positive experiences. Despite it, we can control the thoughts with mindfulness. As Rick Hanson explains, changes in our thoughts can change the grey matter in our brains, and vice versa. "Mental activity is like a spring shower, leaving little traces of neural structure behind," he says. "Over time, the little tracks in the hillside draw in more water down, deepening their course." There are benefits to living mindfully other than happiness. People who try to live more mindfully can focus for longer periods of time. "The ability to focus more... Question: What does Moghaddam think the most important for us? Options: A: Working hard to avoid a sense of emptiness. B: Finding a specific purpose for our own life. C: Relying on our achievements to be happy. D: Seeking happiness from our inner mind.

Q: Read the article and select the best answer. Article: As people in Beijing and northern China struggle with severe air pollution this winter,the toxic air is also making life hard for plants and even food crops of China. "in the last 50 years there has been a 1 6-fold increase in ozone pollution"in the Beijing area,said Hanqin Tian of Auburn University in Alabama,who studies the effects of China's pollution and climate change on plants. Ozone is particularly harmful to plants because it damages the pores on leaves,called stomata,which plants use to regulate how much water evaporates from the leaves.That,in turn,affectS how much water a plant must take up through its roots.Changes in water uptake by plants have been documented in other parts of the world,including the United States,as having major impacts on regional groundwater and surface water supplies. In studies of the long-term productivity of plants,Hanqin Tian and some of his colleagues show that ozone pollution,along with climate change,has been lowering plant productivity in China,which reduces the amount of carbon and other pollutants that the plants Can absorb to fight all the emissions from the burning offossil fuels. The worst effects on plants are likely to be in areas where the growing pollution problem is just fairly new, said Arthur Chappelka, also a plant researcher at Auburn University.Some plants are more resistant to pollutants than others,he said,and the plants that are living today in long-polluted urban areas are likely to be only those that are very pollution tolerant. Away from the cities, however, where crops are necded to feed China's yast population, the effeets of the growing pollution on crops is a significant concern. "In some ways it affects the crop production and food securiy of China,"said Hanqin Tian."Air quality is really important for human health, plants and ecosystem and sustainability." The problem is bound to get worse as China continues to develop economically, he said, and so he and other researchers continue to urge the Chinese government to take action to reduce... Question: ozone does harm to plants mainly by _ . Options: A: exposing them to strong sunlight B: damaging the structure of their leaves C: adding more pores to the roots D: making the land unfit for the plants to grow
