But talk to scientists in private, and many will complain why (besides jealousy, perhaps) are some scientists unhappy with the Nobels? One reason is that the committees can often be slow to recognize achievement. Alfred Nobel specified in his will that the prizes should reward work done in the previous year. But experience soon showed that this was risky, as medals were given out for discoveries that later proved questionable. So a degree of caution is probably advisable. Sometimes, though, it can lead to strange results. Subrahmanyan Chandrasekhar, for instance, had to wait until 1983 to win a prize for work he had done in the 1930s on the structure of stars. However, Albert Einstein never won a prize for his theory of relativity. Even though some pretty suggestive evidence had been produced by Arthur Eddington in 1919, relativity, which has later passed every experimental test ever thrown at it, was still considered somewhat risky and obscure. Another criticism concerns the tradition that no more than three people can share a prize. Science is rarely this clear-cut. Take this year's physics prize, which recognised Peter Higgs for predicting the existence of the mass-bestowing particle that now bears his name. Dr Higgs was only one of several people with a claim. Two other teams---- Rober Brout and Francois Englert, as well as Gerald Guralnik, Carl Hageh and Tom Kibble----- submitted papers on the same idea to the same journal that published Dr Higgs's work, all within a few months of each other. Science often works like this, with different people coming up with similar ideas at similar times. In the event, the committee decided to honour Dr Engler (Brout is dead, therefore unqualified), whose paper was earlier than Dr Higgs's but did not explicitly predict a particle, over Dr Guralnik and his collaborators, who were more comprehensive but published a few weeks later. Question: The passage is most probably coming from_? Options: A: a magazine B: a book review C: a literature work D: a science fiction

Article: Walking in a farmers' market often brings one to explore new food options, and now more locally-farmed protein choices are available to help bridge the gap between our meals and the farms from which they originated. More and more local small farms are popping up in opposition to factory farms. Today's commercial farms do not fit the image that comes to mind while happily singing along to "Old MacDonald". Instead, most of the nation's food comes from CAFOs, Concentrated Animal Feeding Operations, where animals are kept in tightly enclosed conditions as they are fattened up and readied to be killed for food. Fortunately, knowing exactly where one's food comes from has led to an increase in the availability of what is known as "grass-fed" beef. Technically, all cattle are grass-fed for at least a limited amount of time, but what makes the meat significant is that it is grass-finished, not force-fed corn, soy or grains. This change in diet makes all the difference since corn is not part of the cow's traditional diet, and therefore causes major health issues for it. To deal with the health issues, antibiotics are used and some of the antibiotics used to treat the cattle are similar to those given to humans, so they can decrease the effectiveness of medicine when a consumer is sick. A healthier diet for the cattle leads the meat to lower in both fat and calories. And when cooking grass-fed beef, you'd better use a slightly lower temperature to make it more delicious. Question: We can infer from the text that_. Options: A: food from local farms can help add to the variety in our daily meals B: soy or grains are on the list of traditional diets of the cattle C: corn for the cattle leads the meat to lower in both fat and calories D: lower temperature makes grass-fed beef more delicious

However, due to their high price, they have failed to catch on until now. Recently, Ikea has brought out Bekant convertible standing desk that can become a normal desk at the touch of a button. The $500 adjustable desk can transform from a standard desk to a standing one, and Ikea hopes it could make the standing desk mainstream. Experts say that changing from a seated to a standing desk can improve productivity. Similar desks have become a common sight at tech firms such as Google, where some employees have even installed treadmill and bicycle desks. The desk is not the first "convertible" on the market. As early as 2013, Stir Kinect brought out an adjustable desk. The $3,890 Stir Kinect desk has a motor to raise and lower itself, converting it into a standing desk or a traditional desk. The desk can even be programmed to move up and down slightly, making it appear to take a gentle breath to remind the user to change their position. To move between sitting and standing positions, owners simply double tap on the screen. The desk can learn the user's preferences over time and suggest the best seating position. The Stir Kinect desk was created by a team of ex-Apple and Disney engineers. It has a built-in touch screen to control and track movement, and can tell users exactly how many calories they burn by standing during their working day. It also has devices containing power points and USB ports for charging phones, to keep cables hidden. "Ikea's height adjustable desk is great for opening up the lower end of the market, '' said JP Labrosse, founder and CEO of Stir. Question: What can we infer from the last sentence given by JP Labrosse that _ . Options: A: Ikea's adjustable desk will be popular with average people. B: Ikea will have to sell furniture at a lower price in the future. C: This height adjustable table can only be found in Ikea. D: It is not necessary for Ikea to open up the market at all.
