Read the following article and answer the question. Article: Recently, China UnionPay did an experiment in a subway station in Beijing--Are you willing to offer a hand to a stranger who needs help? The leading role of the experiment was an old man. With a small bag in one hand and a large case in the other, the old man appeared in a cold winter morning in the bustling subway station. He was so old that he couldn't carry the heavy case up the stairs. Standing in front of the steps, he looked helpless. Something good happened finally. At 9 o'clock, a kind man showed up, he offered to carry the case for the old man and walked up the stairs with him, at 9:25, another man helped ... Within six hours,the old man walked up the stairs for 25 times,among which he was helped for 23 times. What's more,two ladies tried to help the old man--one in the front and the other in the back. They carried the case up the stairs for him. The most noteworthy thing was that another old man tried to help too. When these kind people were asked why they helped the stranger,they all said " It's just the right thing to do," "I always help people as long as I can" ,or "it's not a big thing, and I just want to help". We often see negative news about fake falling and blackmailing or scheming and cunning. But this experiment brought sheer warmth into our heart. Question: The most moving scene is that _ . Answer:
OPTIONS:
- most of the passers-by helped the old man
- even a disabled girl helped the old man
- another old man also helped the old man
- one lady carried the old man on her back

Answer: another old man also helped the old man

Question: Read the following article and answer the question. Article: "The Lord of the Rings", one of the best sellers in the new millennium , was made up of three parts--"The Fellow Ship of the Ring", "Two Towers", and "The Return of the King". Millions upon millions of people have read it in over 25 different languages, but fewer know about the author and the history of the composition of the creative masterwork. John Ronald Refuel Tolkien was born in South Africa in 1892. His parents died when he was a child. Living in England with his aunt, Tolkien and his cousins made up play languages, a hobby that led to Tolkien's becoming skilled in Welsh, Greek, Gothic, Old Norse and Anglo--Saxon. After graduating from Oxford, Tolkien served in World War I. In 1917, while recovering from trench fever he began composing the mythology for The Rings. As a professor of Anglo-Saxon in the 1930s at Oxford, Tolkien was part of an informal discussion group called the Inklings, which included several writers. The group was soon 1istening to chapters of Tolkien's imaginative work "The Hobbit". Hobbit was a name Tolkien created for people that could best be described as half-sized members of the English rural class. Hobbits live in hillside holes. One of them,Bilbo Baggins, looks for treasures with a group of dwarves . On the way, he meets the twisted, pitiful creature Gollum, from whom he sees a golden ring that makes the holder invisible. One of Tolkien's students persuaded her employer, publisher Allen & Unwind, to look at a draft . The chairman of the firm, Stanley Unwind, thought that the best judge for a Children's book would be his ten-year-old son. The boy earned a shilling for reporting back that the adventure was exciting, and "The Hobbit" was published in 1937. It sold so well that Unwind asked for a continuation. Over a dozen years later, in 1954, Tolkien produced "The Lord of the Rings", a series of books so creative that they hold readers both new and old -- after their publication. Question: What can we learn about "Hobbit" that Tolkien created in his works? Answer:
OPTIONS:
- Hobbit was a race living in English downtown areas.
- Hobbit was a local people who were very tall and strong.
- Hobbit was a social group of people who lived in old castles.
- Hobbit was a group of people who were mostly dwarves.
Answer: Hobbit was a group of people who were mostly dwarves.

Question: Read the following article and answer the question. Article: Jeremy Kerr, a researcher at the University of Ottawa in Canada, and his colleagues analyzed more than 400,000 observations of bumblebee species collected in North America and Europe from 1975 to 2010. When the researchers recorded the locations of these bee populations, they found that many of the 67 species analyzed were moving northward from their southern limits while the northern edges of the bees' ranges are staying in place. What it results in is obvious. Bees have been paid more attention to in recent years, with populations of honeybees and bumblebees obviously declining in some parts of Europe. Previously, attention on the decline of bee populations has focused on causes including habitat loss, pesticide use and the spread of bee parasites . But the work by Kerr's team found something different. "For every species, there is one or two species declining and others that are not moving at all," says Kerr. This shift has also been observed in other species, such as butterflies. But due to a new cause -- the rise of temperatures instead of total pesticide use, a change in land use or parasites, bumblebees -- unlike butterflies -- have failed to extend the northern boundaries of their ranges into the territory that is now habitable for them, so bumblebee species across Europe and North America are declining rapidly, the latest study led by Kerr's team finds. "Our data suggest that the new factor plays a leading, or perhaps the leading, role in this trend," says Kerr. "This study shows that a fourth factor is also beginning to affect it. It is likely that the combined stresses from all of these pressures will have destructive impacts on bumblebees in the not-too-distant future," says Dave Goulson, a bee researcher at the University of Sussex, Brighton, UK. Exactly what can be done to help bumblebees is not clear. Kerr's team suggests that relocating colonies might be an answer but Goulson says that because the insects are mobile they are capable of moving northwards if there is suitable habitat available. Question: Which statement may Goulson agree with? Answer:
OPTIONS:
- Relocating bumblebees isn't much good.
- The findings of Kerr's study are doubtful.
- The future of bumblebees is still promising.
- Knowing bumblebees' living habits is the most urgent.
Answer:
Relocating bumblebees isn't much good.
