Article: The Man Who Never Puts a Foot Wrong Some people do not like anything to be out of place. They are never late for work; they return their books to the library on time; they remember people's birthdays; they pay their bills as soon as they arrive. Mr. Dodds is such a person. Mr. Dodds works in a bank, and lives on his own. The only family he has is in the next town: his sister lives there with her husband, and her son, Mark. Mr. Dodds does not visit his sister, or her family, from one year to the next, but he sends them Christmas cards, and he has not forgotten one of Mark's seventeen birthdays. Last week Mr. Dodds had quite a surprise. He drove home from the bank at the usual time, driving neither too slowly nor too fast. He parked his car where he always parked it, out of the way of other cars, and he went inside to make his evening meal. Straight away, there was a knock at the door. Mr. Dodds opened the door to find a policeman standing on the doorstep. "What have I done wrong?" Mr. Dodds asked himself. "Have I driven on the wrong side of the road? Has there been some trouble at the bank? Have I forgotten to pay an important bill?" "Hello, uncle," said the policeman, "my name is Mark." Question: "The man who never puts a foot wrong" means a person who . Yes or no, is the answer "likes doing things regularly and following rules"?
No

Article: Humans are well-equipped for life on Earth. But in space, it is different. Low or _ changes how the blood flows and causes motion sickness, muscle loss and tiredness. Weightlessness can also cause bone loss. But scientists are experimenting with little worms to better understand how space travel affects astronauts. The millimeter-long worm is called C. elegans. The see-through worm is often used in medical studies because its life is only about two weeks long. Seventy percent of its DNA is the same as human DNA. Sabanayagam is a scientist, who built a micro-gravity simulator to test how C. elegans would perform in the actual zero gravity of space. Scientists put the worms into the simiulator full of water. After a week they take out the worms. They look for changes in the worms' epigenome,which are chemical markers that tell the DNA in the cells how to perform. The epigenome can be changed by the environment. And those changes pass from one generation of worms to the next. "When the worms are in a liquid environment, some epigenomic marks remain even when we take the animal out of the liquid environment and put it back into normal ground conditions. So its offspring keeps this epigenomic memory of the parents' liquid environment or microgravity environment." The information the scientists have gathered suggests that the epigenomic marks appear during the early part of a worm's life. Mr. Sabanayagam says he thinks scientists can find genes in the human similar to those in the worms that responded to microgravity and scientists could possibly observe those genes closely when astronauts travel in space. Sabanayagam expects C. elegans to visit the International Space Station within two years. He says he hopes information gathered from the worm studies can be used to develop simple, low-cost and quick tests to measure an astronaut's health. Question: What is Sabanayagam's attitude toward the result of the experiment? Yes or no, is the answer "Hopeful and satisfied."?
Yes

Article: Could smells affect your lifespan? Female fruit flies rid of the ability to smell food outlive their peers.The sense of smell may be linked to the cellular ageing process in many other organisms--even people.A link has recently been found between sensory experiences and lifespan in both worms and flies.For example, Scott Pletcher, a biologist at the University of Michigan, found that eliminating fruit flies' ability to smell enabled them to live nearly 20 percent longer than flies with an intact sense of smell. Pletcher's team reasoned that food smells were the ones most likely to affect ageing, as nutrition and longevity are known to be linked in many organisms.To test the idea that food odors affect lifespan, Pletcher's team eliminated flies' ability to smell carbon dioxide, which is produced by some fly foods.They left the rest of the smelling system intact. This intervention had no effect on male flies, but the females lived 30 percent longer than normal.Pletcher thinks eliminating the ability to smell CO2may deprive flies of information about food availability.This could signal to cells that food is scarce, causing processes that promote survival.Indeed, his team found that the CO2-insensitive female flies stored extra fat and that both males and females immune to CO2were more resistant to stress than normal flies.Pletcher isn't sure why the change in his fruit flies only affected the lifespan of the females, but he suggests that females may simply be more sensitive to the odor of CO2. A smell or taste that stretches lifespan in humans could be a potential preventative for age-related disease, he adds.Although in fruit flies it appears to be the smell of CO2that affects ageing, he says that an analogue in humans might be a smell or taste linked to human food--or a lack of it.Matt Kaeberlein studies ageing at the University of Washington in Seattle. He cautions that we don't know whether ageing and smell are linked in mammals.But " we definitely undergo physiological changes in response to smelling... Question: According to the results of Pletcher's study, we can see that _ . Yes or no, is the answer "flies without ability to smell is inspired to find food in another way"?
No
