input: Please answer the following: Write a multi-choice question for the following article: Article: Scientists have found what look like caves on Mars , and say they could be protecting life from the planet's terrible environment. The first caves discovered beyond the Earth appear as seven mysterious black dots on the pictures sent back by NASA's Mars Odyssey orbiter. Each as large as a football field, they may be openings into natural caves below the Martian surface. "If there is life on Mars, there is a good chance you'd find it in caves," said Jut Wynne, one of the researchers who noticed the features while working on a US Geological Survey Mars Cave Detection Program. Jonathan Clarke, a geologist with the Mars Society of Australia, yesterday described the discovery as exciting. One photo taken at night by an infrared imager showed one hole to be unusually warm, suggesting hot air trapped during the day is flowing out. "I said: 'Wow, that's a cave'" Dr. Clarke said excitedly. "People have been looking for these for a long time; now we have found them." He agreed such caves would be perfect places to hunt for life escaping from the bitterly cold, radiation-soaked , dry surface. "Tiny drops of water could collect inside," he said. "If there are gases coming out, they could provide energy for a whole range of bacteria. A cave is also a protection from radiation; the surface of Mars is exposed to high levels of space radiation." The caves probably formed when tube-shaped lave flows spread across the planet long ago. The outside of the tubes cooled, forming solid walls, while something hotter inside allowed the remaining have to flow out, forming caves.

Problem: Write a multi-choice question for the following article: Article: Scientists have produced new evidence suggesting eating lots of red and processed meat damages health. They found big meat eaters had a raised risk of death from all causes over a 10-year period. In contrast, a higher intake of white meat was associated with a slightly reduced risk of death over the same period. The US study, based on more than 500,000 people, found those whose diet contained the highest proportion of red or processed meat had a higher overall risk of death, and specifically a higher risk of cancer and heart disease than those who ate the least. People eating the most meat were eating about 160g of red or processed meat per day-- approximately a 6oz steak. Those who ate the least were only getting about 25g per day-- approximately a small piece of bacon. Just the opposite, those who ate the highest proportion of white meat had a lower risk of overall death, and a lower risk of fatal cancer or heart disease than those who ate the lowest proportion. Meat is a major source of saturated fat, which has been associated with breast and colorectal cancer. In addition, lower meat intake has been linked to a reduction in risk factors for heart disease, including lower blood pressure and cholesterol levels. The latest study adds to a growing body of research linking high red and processed meat consumption to an increased risk of ill health. Ed Yong, of the charity Cancer Research UK, said, "Evidence from large studies tells us that cutting down on processed food, such as bacon or burgers, can reduce the risk of dying from cancer and other diseases." Dr Barry Popkin of the University of North Carolina stressed there were health benefits from eating some red meat. But he added: "The need is for a major reduction in total meat intake, an even larger reduction in processed meat and other highly processed and salted animal source food products and a reduction in total saturated fat." Dr Mark Wahlqvist, a nutrition expert from Australia, said eating small amounts of red meat--around 30g a day--provided...

input question: Write a multi-choice question for the following article: Article: Four out of ten women who diet end up heavier than when they started watching their waistline, a study revealed today. The research also showed that a large percentage of women start noticing the pounds creeping back on just 21 days after reaching their ideal weight. Yesterday, Dr Ian Campbell of the Jenny Craig weight management program said, 'In the UK 61.4 percent of adults are overweight or obese. Successful weight management requires a long-term commitment in order to lose weight successfully and for good. Dieting can be a real challenge so setting realistic goals and remaining focused on them is important. Otherwise as this research shows, women could end up heavier than when they started.' The "Food, Body, Mind" report was publicized by Jenny Craig who quizzed 2000 women aged between 18 and 65 who diet regularly on their attitudes, beliefs and behaviors around weight loss. Six in ten said they were currently on a diet and one in five women said they were on a continuous diet. It found the most common triggers to start dieting was seeing their reflection in the mirror, preparing for a summer holiday or unflattering photos posted on social networking sites. Other popular reasons include comments by friends or relatives or their other half. However, the study showed that one in ten give up within one day, while almost a fifth manage to make it to a week or more. The average is ten days. Many blamed pressure they put on themselves to lose weight too quickly for the weight gain, which leaves them with a bigger appetite than normal. Others blamed colleagues, who tuck into fatty lunches and snacks unaware of the effect it has on the dieter, while mothers' polishing off their children's leftovers was another common cause of weight gain.???
