Article: Some pigs lend lo be optimistic while others have a more pessimisitic view , according to a new research that is meaningful to animal welfare. The study, published in the journal Biology Letters, is the first to show that mood and personality interact in an animal, influencing judgment. Asher, a researcher at ihc University of Newcastle's Institute of Neurowcience, and her team housed groups of pigs in the two types of environments. One reflected sandard commercial conditions and the other was _ with more space and plenty of sell, deep straw. After the pigs got accusitomed to these new homes over a few weeks , the rescarchers picked 18 pigs from each type of housing arrangement to train and test their judgment. " To do this, we trained each pig that in one comer of a training room there would be a bowl wilh chocolate sweets -- specifically M&Ms, pigs love M&Ms -- and in a bowl at the opposite side of the room there would be a bowl that would contain coffee beans, which pigs find bitter-tasting," senior author Lisa Collins of the Univerersty of Lincoln's School of Life Sciences said. Over n number of training trials , pigs leamed to go to the bowl reliably when it was in the corner where they had figured out to expect M&Ms.On the contrary,they quickly leamed to avoid the bowl when it was't in the comer where they would expect to find the coffee beans. The rescearchers next placed an unfamimliar bowl in different locations , to see how the pigs would react. Some gaily dashed to the bowl no matter what, exhibiting optimism that it would contain there favorite sweds. Others, however, behaved as though they expected it to contain coffee beans, displaying pessimism. The findings suggest that a one -- size- fits - all answer to animal welfare issues does not exist. Even if pigs are just equal lo bacon or other meal for some people, there is still cause for conccrn . Student have suggested that how an animal is trented during is lifetime can directly affect... Question: What do the findings of the new research imply? - People should treat pigs equally. - People's health relies on meat quality. - People should meet pigs' various needs. - People's attitude toward pigs is totally wrong.
People should meet pigs' various needs.

But officials warned that it was too early to say whether the eruption was over completely. Ash clouds from the volcano grounded thousands of flights last month. Steinunn Jakobsdottir, a geophysicist from the Icelandic Meteorological Office, told the BBC that the volcano was "kind of not active for the moment". "The history of the volcano is such that it calms down and then it gets energy again," she said. "There are still earthquakes under the volcano, and the small earthquake is still not quite down to what it was before the eruption." 'Difficult to say' Magnus Gudmundsson, of Iceland University, flew over the volcano on Sunday and said information from heat cameras showed the temperatures at the crater had fallen below 100C. But he told the AFP news agency that nothing was promised and that the previous eruption at the volcano had lasted 13 months, from 1821-23. "It stopped and started again several times with different intervals , so it's difficult to say, difficult to give a timeline," he said. He also said it was impossible to say whether the neighbouring Katla volcano - a much larger mountain - might also erupt. At the height of its activity, the volcano sent out huge clouds of ash, which led to airlines grounding their planes for fear it could _ plane engines. It was the biggest action of closing airspace in Europe since World War II, and affected at least 10 million passengers worldwide. Question: What do expert think Eyjafjallajokull is like now? - Magma is still coming out - The hole appears about 100 degrees C - The eruption was not over - It is very cold.
The hole appears about 100 degrees C

Q: Read the following article and select the best answer. Article: Animals are being killed by hunters in America in a cruel way, says an animal protection organization. There are about 1,000 hunting farms across America whose owners offer hunters an opportunity to kill animals that are kept in fenced areas. Russian boar, zebra, deer, antelope and many other species are raised just to be killed. Farm owners charge hunters thousands of dollars for animals that they kill, many of which are close to extinction . The Humane Society of the United States says this type of hunting should be stopped because it is not fair to the animals. Many owners raise their animals. Others buy from animal dealers or from zoos and circuses that no longer want them. This means that the animals are not afraid of humans and they are easy to be shot by hunters. Owners of small ranches keep their animals in fenced areas so that the hunters can get close to the animals before shooting at them. On large farms hunters are taken to areas where the animals are fed sometime of the day. This also makes it easy to kill the animals. The hunters want to keep the heads and chests of the animals they kill to hang as trophies on their walls. This means that the animals are usually shot in parts of the body. That means they will suffer a slow and painful death. The hunting is allowed across most of America but some parts of the country have stopped or restricted it. The Humane Society of the United States hopes that it won't be too long before the rest parts of the country also give up this cruel sport. Question: One of the main reasons why these animals are easy to be shot is that _ . - they don't run very fast - they are not afraid of humans - they don't know how to escape - the hunters are good at shooting
A: they are not afraid of humans

Q: Read the following article and select the best answer. Article: Everyone knows that eating too much junk food is not good to our health. Yet, what is it about junk food that is so completely irresistible ? For one thing, it's everywhere. From chips in fast food restaurants to candy in supermarkets, junk food always seems available. Thankfully, science is now providing new clues to help us reduce snacking. Make friends with dainty eaters. Studies have found that people tend to increase or reduce the amount of food they eat depending on what their companions are taking in. See happy movies... and always get the smaller bag of popcorn . According to some experts, people eat up to 29% more popcorn if they are watching a sad or serious movie, compared to when they are watching a comedy. Viewers consumed almost 200 calories more when snacking from a large bucket, as opposed to when given a medium-sized container. Eat breakfast. Nutritionists have gone back and forth about the question of how much to eat in the morning, but new studies suggest that consuming a good breakfast is a must. Surveys on long-term weight-loss show that two key factors in keeping weight down are eating breakfast and exercising. Divide your food and conquer overeating. Any kind of dividing your food into portions slows down your eating. Any kind of marker makes you aware of what you're eating and of portion size. Researchers advise reallocating snack foods into small plastic bags. It sounds simplistic, but it works. Question: What is the text mainly about the rule(s)? - how to make friends with dainty eaters. - how much to eat in the morning. - how to control overeating. - how to eat properly and healthily.
A: how to eat properly and healthily.
