Read the following article and select the best answer. Article: One of the biggest accomplishments in sports in the last hundred years was the 4-minute mile. Running a mile in under 4 minutes was a huge barrier in sports. Once it was broken by one person, lots of athletes tried to break it too. For years, people thought that running a mile in less than 4 minutes was just _ impossible. It was common knowledge that nobody on earth could physically run a mile in under 4 minutes. Professional runners had been trying for years, training to beat that time, but had failed every time. In 1952, a British man by the name of Roger Bannister set a goal for himself: to be the first person to run a mile in under 4 minutes. He trained intensely, and 2 years later, Bannister finally broke 4-minute barrier. And you know what? Soon after that, more and more people began to run the mile in under 4 minutes. New world records were set almost every year following Bannister's sub-4-minute-mile. Nowadays, even a high school student can reasonably run a 4-minute mile. In about 50 years, the 4-minute mile went from impossible to professional to amateur. But I guess I'm not really answering the question here: what on earth does this have to do with learning Japanese? When you have a goal in mind, mental barriers can be huge obstacles to overcome, and learning Japanese is no different. But if you're devoted enough and make your goal your top priority , you might be surprised at what you can do. Put everything else aside for a while, just go for it and see what you can achieve. After all, if somebody can accomplish something that people thought was physically impossible, then maybe learning Japanese isn't so hard after all. Question: According to the passage, we can know that _ - all the high school students can run the mile in under 4 minutes - high school students try to break records in the sports field - learning Japanese is not difficult at all - mental barriers are the biggest ones when achieving goals
mental barriers are the biggest ones when achieving goals

Read the following article and select the best answer. Article: Fish species are expected to shrink in size by up to 24% because of global warming, say scientists. The scientists argue that failure to control greenhouse gas emissions will have a greater effect on marine ecosystems than previously thought. Previous research has suggested that changing ocean temperatures would affect both the distribution and the reproductive abilities of many species of fish. This new work suggests that fish size would also be heavily affected. The researchers built a model to see how fish would react to lower levels of oxygen in the water. As ocean temperatures increase, so do the body temperatures of fish. But, according to lead author, Dr William Cheung, from the University of British Columbia, the lower level of oxygen in the water is key. Warmer waters could decrease ocean oxygen levels and greatly reduce fish body weight. On the other hand, rising temperatures directly increase the metabolic rate of the fish's body function. This leads to an increase in oxygen demand for normal body activities. So the fish will run out of oxygen for growth at a smaller body size. The research team also used its model to predict fish movements as a result of warming waters. The group believes that most fish populations will move towards the Earth's poles at a rate of up to 35km per decade. "So in, say, the North Sea," says Dr Cheung," one would expect to see more smaller-body fish from tropical waters in the future." Taking these factors into consideration, the research team concludes that fish body size will shrink between 14% and 24%, with the largest decreases in the Indian and Atlantic oceans. When compared with actual observations of fish sizes, the model seems to _ what's actually happening in the seas. The researchers looked at two case studies involving North Atlantic cod and haddock. They found that recorded data on these fish showed greater decreases in body size than the models had predicted. Dr Alan Baudron, from the University of Aberdeen, UK, believes smaller-sized fish could seriously... Question: What is the key factor making the fish smaller now? - The rising body temperatures. - The lower level of oxygen in the water. - The increasing metabolic rate. - The normal body activities.
The lower level of oxygen in the water.

Read the following article and select the best answer. Article: Grace Kane hangs onto an Olympic dream of clinging to a granite wall by her fingertips 70 feet from the ground. The fearless girl is only 10, but already has scaled great heights in the sport of rock climbing. Last week, Kane won a bronze in the 11andyounger sport class at the USA Climbing Youth National Championships in Atlanta. She was the only competitor of the 31 there with no climbing coach or topflight facilities in which to train. Climbing will become an exhibition at the 2016 Rio de Janeiro Olympics in Brazil. The hope of enthusiasts is that the sport will gain full status in 2020."I'm already training for that," said Kane. "Climbing is my passion, my love, and I want to make something of it." Her dad took her to climb rocks on her fourth birthday for the first time and today he can't keep up with her, "It's the freedom to let loose," she said. "When I'm up there, I'm so focused and don't hear anything. I always feel comforted knowing people are supporting me." The bronze in Atlanta qualified Kane for the USA team and November's International Championships in Ecuador. That's a trip she might have to miss because it's too expensive. Kane held a backyard music concert---she played the guitar and the piano and wrote inspirational songs---and raised $600 for her $1,500 trip to Atlanta. She's also been sponsored by a shoe company, but must rely heavily on donations from family and friends for travel expenses. Her mom Heather Kane said the family has chosen "to do whatever we need to help her achieve her goals". One of Grace's biggest challenges is finding balance in her life. There's school, her music and church to fit around climbing. "Climbing is going to mean sacrificing things other kids might pursue," Grace said. "But it doesn't bother me. It's like playing the piano; you can't take a break or you'll lose your touch." Question: What would be the best title of the passage? - Rock climbing gains popularity - Grace Kane likes challenges - A young climber follows her dream - An amazing victory for a young rock climber
**Answer**
A young climber follows her dream
