Ques: Article: It's a sure sign that summer is over and winter is on the way -- leaves that were once deep green turn red, yellow and bright orange. It happens every autumn. But did you ever wonder why? The leaves start changing color when the nights start getting longer and the temperature starts getting cooler. Some scientists think that as the number of daylight hours _ the leaves stop making chlorophyll which makes plants green. The reason is that the process of making chlorophyll requires sunlight. But according to horticulture educator Susan Rose from Colorado State University, it turns out leaves don't really change color at all. "The fall colors are actually there all along," she said. "But they are covered by the green chlorophyll. As the chlorophyll stops being produced, the other colors can shine through." The kind of color that the leaves are going to change to is determined by the plant's genetic background. In some places, the leaves start changing color in September -- before autumn even officially begins. In other places, they don't change until late October or even November. Some scientists say the leaves have been changing color later than usual in recent years. And they think global warming has something to do with that. In one study, researchers found that the growing season in the Northern Hemisphere was nearly a week longer, on average, in 2008 than it was in 1982. And a professor from Harvard University found that the leaves, west of Boston, Massachusetts, are changing color about three days later than they used to. However, other scientists disagree with the global warming theory. Susan Rose said the leaves in her part of Colorado are changing "right on schedule." But the leaves in other parts of that state are running a little late. "The lateness in the mountains may have something to do with the really warm late summer and early fall," she said. "But I'm afraid that's just a guess." Question: Scientists guess leaves change color later than usual probably as a result of _ . Yes or no, is the answer "global warming"?
Ans: No

Ques: 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... Question: Processed meat is a kind of _ . Yes or no, is the answer "meat prepared by producers"?
Ans: No

Ques: Article: COLUMBUS, Ohio--The heart operation taking place in the pale-green operating room at the Ohio State University Medical Center was unusual. The patient, a 62-year-old man, was made to sleep, tied with blue drapes and lying face up on a narrow table. But no one was touching him. Instead, the operation was being performed by a robot, whose three metal arms went through pencil-sized holes in the man's chest. At the ends of the robot's arms were tiny metal fingers, with turning wrists, which held a tiny instrument, a light and a camera. The robot's arms and fingers were controlled by Dr. Randall K. Wolf, sitting at a computer in a corner of the operating room about 20 feet away. This sort of operation, heart surgeons say, is the start of what may be the biggest change in their profession since heart bypass surgery began nearly 30 years ago. "The reason we make cuts is that we have big hands," said Dr. Wolf, the director of the surgery at Ohio State. The robot's _ fingers, no longer than a nail on the small finger, at the end of the long sticks could work better. Eventually, surgeons believe, most heart surgery will be done by robots whose arms are put in through pencil-sized holes punched in patients' chests. Instead of directly staring into a patient's body, surgeons will view magnified images of the operation on computer screens. In theory, the doctor would not have to be in the same room, or even the same country, as the patient. Question: The main idea of this passage is that heart surgery by robots _ . Yes or no, is the answer "may replace surgery done by doctors"?
Ans:
No
