[Q]: Write a multi-choice question for the following article, with the given choices and answer: Article: While engineers have made out fantastic products for sitting still--Munchery instead of walking to lunch, Uber instead of walking to the bus stop--services to make you move have been less appealing for consumers. Fitbit's stock price fell 18% after they announced their latest Apple Watch-like product named Fitbit Force. And new data suggests that, for the first time, death rates for large parts of the American population are rising, with signs pointing to inactivity and weight gain as the reasons. Our digital lifestyles and desk-based workplaces are contributing to serious health problems and could be shortening our lives, wellness firms want us to believe. Northrup, president and co-founder of the connected exercise device TAO-Wellness, was in Las Vegas to promote TAO's small device that encourages exercises. He lifts the device, about the size of an apple, and says workplaces should start encouraging on-site exercise. Nick Mokey, the managing editor of Digital Trends, agrees. "I hate to break it to you, a room full of people sitting down, but sitting is killing you," he says to the audience. They shift in their seats. In the health section of the Sands Exposition Hall, people are selling devices made by LifeSpan Fitness. They say they're the largest seller of treadmill desks in the US. At the center of their exhibition area is a Bike Desk, which looks like three gym bikes attached to a table. That's for people who just want to sit and enjoy conversation. Treadmill desk-related shame is their biggest obstacle, they say when LifeSpan installs two in opposite ends of the same building, neither tends to get used. If the company installs two next to each other, people will use them. "You don't want to be so noticeable, especially at work," company spokesman James Lowe says. What's more, what if we get sweaty using a treadmill in the office? Options: A It takes up too much space. B It is not comfortable to use C It may cause awkwardness D It will make employees tired Answer: C It may cause awkwardness Question:

[A]: What is the biggest problem with the treadmill desk?

input: Please answer the following: Write a multi-choice question for the following article, with the given choices and answer: Article: People who drink moderately , exercise, quit smoking and eat five servings of fruit and vegetables each day live on average 14 years longer than people who adopt none of these behaviors, researchers said on Tuesday. Much evidence has shown these things contribute to healthier and longer lives, but the new study actually quantified their combined effect, the British team said. "These results may provide further support for the idea that even small differences in lifestyle may make a big difference to health in the population," the researchers wrote in the journal PLoS Medicine. Between 1993 and 1997 the researchers questioned 20,000 healthy British men and women about their lifestyles. They also tested every participant's blood to measure vitamin C intake, which shows how much fruit and vegetables people ate. Then they assigned the participants aged 45-79 a score of between 0 and 4, giving one point for each of the healthy behaviours. After allowing for age and other factors that could affect the possibility of dying, the researchers determined people with a score of 0 were four times as likely to have died. Also a person with a health score of 0 had the same risk of dying as someone with a health score of 4 who was 14 years older. The lifestyle change with the biggest benefit was giving up smoking, which led to an 80 percent improvement in health, followed by eating fruits and vegetables. Moderate drinking and keeping active brought the same benefits. With this information, public-health officials should now be better encouraging behavior changes likely to improve the health of middle-aged and older people. Options: A A 15-year-old student. B A 25-year-old soldier. C A 35-year-old teacher. D A 45-year-old housewife. Answer: D A 45-year-old housewife. Question:

output: Who is the most likely to benefit from behavior changes according to the passage?

Problem: Write a multi-choice question for the following article, with the given choices and answer: Article: The American local food movement has been all about buying seasonal food from nearby farmers. Now, thanks to the Web, it is expanding to include far-away farmers too. A new start-up, Foodzie, is an online farmers market where small food producers and growers can sell their products. Foodzie was started by Mr LaFave and two of his friends, who met during college at Virginia Tech, where they would pay frequent visits to farmers markets. Last year, while living in North Carolina, one of them, Emily Olson, now 24, came up with one idea. She was working as a brand manager for a _ grocery chain and realized that people who enjoyed fine food but didn't work in the business had no way to discover handmade foods outside their local farmers markets. Small farmers had no way of finding or selling to faraway customers, either. Mr LaFAve and the third co-founder, Nik Bauman, both 25, worked in corporate sales and software development. "With business, food and computer science backgrounds, we figured we had everything we needed." Mr LaFAve said. The three quit their jobs, and opened this site to the public in December and the site has had 43,000 visitors in the past month. So far, 29 sellers have opened shops and 41 are in the process of opening them. The founders recently hired a fourth employee to help Ms Olson recruit new food producers at farmers markets and food shows. Mr LaFAve is convinced that the recession will not reduce people's interest in buying locally grown and handmade food. "There is misunderstanding that all these foods are more expensive than mass-produced alternatives," he said. "People are pouring their heart and soul into these products, and they are of the highest quality." Options: A how an online farmers' market works B the American local food movement C three youths starting an online farmers' market D the reasons why people are interested in local food Answer: C three youths starting an online farmers' market Question:

A:
The passage is mainly about _ .
