I'm taking a test and have to guess the right answer to the question after the article. Article: Few of us make money by losing sleep.But three graduate students at Brown University in Providence built a company around sleep deprivation . Jason Donahue, Ben Rubin and Eric Shashoua were working late nights in Brown's business and engineering schools.They began thinking about ways to sleep better.They discovered they weren't alone in burning the midnight oil.Around 20% of Americans get less than six hours of rest a night. The friends imagined a smart alarm clock that could track how much time people spend in the most restorative stages of the sleep cycle: REM (rapid eye movement) and deep sleep.What would it cost to design such a thing? Five years of research, 20 employees, $14 million and a whole lot of doubting from investors and scientists. Their company, Zeo, based in Newton, Mass, launched its product in June, 2009.The Zeo device uses a headband with tiny sensors that scan your brain for signs of four sleep states- REM, light, deep and waking sleep.The smart alarm clock displays a graph of your sleep pattern and wakes you as you're not in REM sleep (which is when you're least groggy).In the morning you can upload the data to the company's Web site, and so track your sleep over time.Most of the feedback comes in the form of Zeo's ZQ score showing how well you've slept. "Zeo allows people to unlock this black box of sleep," says Dave Dickinson, a health-care CEO. Whether any of this actually improves sleep is up to the consumer, who will also need to make lifestyle changes like cutting out alcohol before bedtime or caffeine after 3 pm. For now the company is selling Zeo online only.Dickinson also plans to spread it to countries such as Australia, where sleep deprivation approaches US levels. Question: What can we know from the passage? Options: A: Zeo has a direct effect on users' lifestyles. B: It needs more personal efforts to make Zeo function better. C: A large quantity of Zeo devices have been sold in Australia. D: Consumers can go to the Zeo company to purchase Zeo in person.

I'm taking a test and have to guess the right answer to the question after the article. Article: It all starts with a tree.In fact, it starts with several trees.Since the first modern guitars were made in northern Spain over 150 years ago, crafts persons have known the wood to be used is important in making a guitar. Every guitar is made of several different kinds of wood.Each piece is carefully chosen and then cut to fit the part of the guitar for which it is designed.The most important part of a guitar is the soundboard--the piece of wood with a large hole that lies under the strings(,).Guitar makers are careful to make the soundboard just the right shape and thickness.Then they fix stripes of wood across the inside in a special pattern, which helps strengthen the soundboard and improves the tone of the guitar. Wood for the curvy sides of the guitar must be soaked in water and bent over a hot iron pipe.When all the pieces of the guitar are ready, they are carefully stuck together with glue .Special woodworking tools are used to shape and smooth the neck of the guitar.The craftsperson must make sure that the neck is perfectly centered over the soundboard. Then it is time to use varnish .This brings out the beauty of the wood.Varnish also improves the sound of the guitar but too much varnish makes the guitar sound flat and dull. Finally guitar strings are attached and tightened to make just the right musical tones.Then it's time to play a song. Question: The best title for this passage may be_.

I'm taking a test and have to guess the right answer to the question after the article. Article: For many workers trying to lose weight, the weekend is a chance to do some exercise and eat something healthier than a supermarket sandwich at their desk. But some slimmers take a slightly different approach -- consuming more than half their weekly calorie intake from Friday night to Sunday. Away from the daily routine at work that helps them keep control of what they eat, they are snacking and drinking their way to a shocking 10,000 calories, a survey has found. Almost three-quarters of people trying to lose weight admit to over-eating at the weekend. A meal with friends or family, complete with alcohol, as well as a late-night snack before bed, can lead to adults consuming up to 3,500 calories in one day, a survey found. Men typically need 2,500 calories a day and women 2,000 calories. Consuming this amount would see men and women get through half their weekly calorie intake over the course of a 'bad' weekend. Women were found to eat less on a Sunday because of guilt over their consumption over the previous two days. Men had fewer doubts about a third day of excess. The biggest weekend diet danger comes from snacking between meals, the survey found. Some say they will often spend Saturday night in front of the TV with their families -- combining watching their favorite shows with crisps and biscuits. And seven in ten people admitted to having fattening takeaways at weekends, with pizza the most popular. Alcohol is another big factor in weekend bingeing.Around 70 percent still like to have a roast on a Sunday or a big meal with family or friends and a third of those will have second helpings. A spokesman from Forza Supplements, the diet company that conducted the survey, said, "We all have bad weekends where we have a lot of fun, but dieting goes out of the window." The 5:2 diet is becoming increasingly popular -- where we limit our calories for five days and allow ourselves a few treats on the other two days. "For many people, the two days off are Saturday and Sunday but they go way too far" Question: What is the main idea of the text? Options: A: Weekends are vital for diets. B: What the 5:2 diet is. C: The proper way to lose weight. D: People's weekly calorie intake is changing.
