Write a multi-choice question for the following article, with the given choices and answer: Article: Does happiness have a scent? When someone is happy,can you smell it? You can usually tell when someone is happy based on seeing them smile,hearing them laugh or perhaps from receiving a big hug.But can you also smell their happiness? Surprising new research suggests that happiness does indeed have a scent,and that the experience of happiness can be transmitted through smell,reports Phys.org. For the study,12 young men were shown videos meant to bring about a variety of emotions while researchers gathered sweat samples from them.All of the men were healthy and none of them were drug users or smokers,and all were asked to abstain from drinking or eating smelly foods during the study period. Those sweat samples were then given to 36 equally healthy young women to smell,while researchers monitored their reactions.Only women were selected to smell the samples,apparently because previous research has shown that women have a better sense of smell than men and are also more sensitive to emotional signaling--though it's unclear why only men were chosen to produce the scents. Researchers found that the behavior of the women after smelling the scents--particularly their facial expressions--indicated a relationship between the emotional states of the men who produced the sweat and the women who sniffed them. "Human sweat produced when a person is happy brings about a state similar to happiness in somebody who breathes this smell," said study co-author Gun Semin,a professor at Koc University in Turkey. This is a fascinating finding because it not only means that happiness does have a scent,but that the scent is capable of transmitting the emotion to others.The study also found that other emotions,such as fear,seem to carry a scent too.This ensures previous research suggesting that some negative emotions have a smell,but it is the first time this has proved to be true of positive feelings. Researchers have yet to isolate exactly what the chemical compound for the happiness smell is,but you might imagine what the potential... Options: A Men produce more sweats. B Negative emotions have a smell. C Pleasant feelings can be smelt out. D Women have a better sense of smell. Answer: C Pleasant feelings can be smelt out. Question:

Write a multi-choice question for the following article, with the given choices and answer: 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. 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. Answer: B It needs more personal efforts to make Zeo function better. Question:
