Article: Penguins can taste only sour and salty food, scientists have discovered. A genetic study suggests the flightless birds lost three of the five basic tastes long ago in evolution. Taste is critical for survival in most animals, but may not matter in the penguin, which swallows fish whole, say researchers in China and the US. Many other birds are unable to taste sweet things, but they do have receptors for detecting bitter and umami (or meaty) flavours. The discovery was made when researchers decoding penguin genomes found some of the taste genes were missing. A closer look at the DNA of penguins revealed that all species lack functioning genes for the receptors of sweet, umami, and bitter tastes. "Based on genetic data, penguins are believed to have sour and salty tastes, but have lost sweet, umami, and bitter tastes," lead researcher Prof Jianzhi Zhang, of the University of Michigan, US, and Wuhan University, China, told the reporter. The umami taste gives food the strong, savoury flavour associated with meat. Lacking this sense is surprising for a carnivorous animal, but does not matter that much in the penguin, which swallows fish without chewing. "Their behaviour of swallowing food whole, and their tongue structure and function, suggest that penguins need no taste perception," said Prof Zhang. "Although it is unclear whether these traits are a cause or a consequence of their major taste loss." The findings, published in Current Biology journal, were a puzzle, he added. One clue comes from the bird's evolution on the frozen ice sheets of Antarctica. Sending signals from sweet, umami, and bitter (but not sour or salty) taste receptors to the brain does not work at very low temperatures. This may have led to the penguin gradually losing its sense of taste, say the researchers. Intriguingly , the sweet taste is missing in almost all birds. The hummingbird, which feeds on sweet nectar, is an exception. Question: What's the best title of the passage? Yes or no, is the answer "Penguins lost ability to taste fish"?
No

Article: "Drink your milk. It's good for you!" You've probably heard that many times, and it's true. Milk contains calcium , which is necessary for keeping bones and teeth healthy and strong. The US government even requires milk as part of the National School Lunch Program, saying that students should drink one cup of fat-free or low-fat milk every meal. However, a group of doctors asked the government to take it away from the lunch program. The US 'Physician Committee for Responsible Medicine (PCRM) says, "Milk is high in sugar, fat and animal protein," all of which have negative effects on health. The PCRM says there are better and healthier ways to get calcium such as eating beans, broccoli, cereals and tofu. Orange juice and soymilk that have calcium added to them also supply the nutrient. "One of the only reasons people prefer milk is that it is going to help build strong bones," says Dr Neal Barnard, president of the PCRM. But milk may not be the best way to get calcium your body needs. Of course, calcium is important for healthy bones and teeth, but there are other things that affect your bone strength, such as genes, how much vitamin D you take in, and getting an hour's worth of exercise every day. Some people disagree with the idea that milk isn't important. Keri Gans, an American Dietitian, says "I don't think it's irresponsible to take this beverage that children enjoy it very much, especially among those who are unable to meet their nutrient needs for the day, and remove it from the lunch line." The U.S government is now considering the request of the PCRM, but a decision may be a long way off. Meanwhile, Marion Nestle, a professor puts it best: "Milk certainly has nutrients. Other food has the same nutrients. It's just food. As with other food, too much might be a problem." Question: The PCRM proposed that milk be removed from the lunch program because _ . Yes or no, is the answer "drinking milk is not the best way to get the calcium your body needs"?

No

Ques: Article: The disadvantage you usually find about MP3 players like the iPod is that they are too big. But get ready for the MP3 player in your hand to get much smaller--the size of a Band-Aid . It's called the Skinny Player, and it's being designed by industrial designers Chih-Wei Wang and Shou-His Fu. Unlike the current types of iPod Shuffles and iPod Nanos, the Skinny Player does not need to be fixed onto your clothes or put into your pocket. It could stick to your skin like you would attach a Band-Aid. But unlike Band-Aids, this tiny MP3 player will not lose its stickiness as you pull it off for the hundredth time. The Skinny Player features flexible speakers allowing the user to enjoy music conveniently. When it gets dirty, the user can simply clean it using a damp cloth. No batteries either. The Skinny Player's designers say it will be powered by body heat, using a flexible battery charging device that is in contact with skin whenever the player is being used. The design only include an on/off button and flexible speakers, no word yet on arranging the volume. Besides, the memory capacity won't be the best, as it is designed to only store one album. The small size and the ability to stick it onto your skin like a Band-Aid should make the Skinny Player perfect for runners who now depend on their iPod to keep them energized on the running path. Question: The Skinny Player has all the advantages except that it's _ . Yes or no, is the answer "larger in memory capacity"?
Ans: No

Question: Article: People should go outside and absorb some sunshine to help increase their vitamin D levels, some experts say. Arthritis Research UK. which is a British medical research organization dedicated to curing arthritis , says vitamin D deficiency can cause bone loss, muscle function problems and, in some cases, rickets in children. The government recommends vitamin D supplements for pregnant women and children aged under five. But on sunny days, a few minutes outdoors should achieve the same results, Arthritis Research UK says. Figures show that up to a quarter of the population has low levels of vitamin D in their blood and the majority of pregnant women do not take vitamin D supplements. People aged over 65, pregnant and breast-feeding women and children aged six months to five years old are thought to be most at risk. Vitamin D is essential to help the body absorb calcium from food. Low levels of vitamin D can result in serious problems. Alan Silman, the medical director of Arthritis Research UK, said, "When the days are sunny, go out for a few minutes and expose your face and arms to the sunshine." But he also had a warning on overexposure. "Don't allow your skin to go red, and take care not to burn, particularly in strong sunshine and if you have fair or sensitive skin. From June to August, just 15 minutes is generally enough time." "In less sunny months," Alan Silman added, "we recommend that people add more vitamin D in their diet by eating more oily fish such as salmon, tuna, and foods rich in vitamin D, such as cereals ." Question: Lack of vitamin D may cause the following problems EXCEPT _ . Yes or no, is the answer "high blood pressure"?
Answer:
No
