Example Input: Article: Harvard University in the United States has been ranked as the university with the best "reputation" in the world. The Times Higher Education magazine has listed 200 top universities all over the world based on how they are regarded by a group of international college teachers. That is to say the list measures how universities are regarded, rather than how they actually performed. A subjective, word-of-mouth quality such as "reputation" has genuine economic value for universities, said Simon Marginson, professor of higher education at the University of Melbourne in Australia. "Reputation is not just an impression, though it might be not as reliable as performance by objective indicators ," said Prof Marginson. Based on the views of 13,000 college teachers around the world, it confirms the power of the big US universities, which _ this list. Seven of the top 10 are US universities, headed by Harvard and Massachusetts Institute of Technology (MIT). Furthermore, 14 of the top 20 are from the US. Cambridge is the highest ranking UK university in the list, in third place, with Oxford ranked as sixth. For students applying to university, reputation might be hard to quantify, but was an important part of the attractiveness, said the president of Cambridge University's students' union, Rahul Mansigani. "Reputation makes a huge difference. If there is an idea that somewhere is great, it will get lots of good people applying whether it's true or not. Factors such as a sense of history and the presence of outstanding college teachers were part of the reputation of Cambridge," he said.
Question: What can be inferred from the text?
Options: (A) No Asian universities are among the Top 10. (B) At least five UK universities are among Top 20. (C) The Times Higher Education magazine is from the US. (D) Reputation affects students' decisions when choosing universities.
Example Output: D

Example Input: Article: Not being the best but touching the limits of your ability. This belief came from my third grade teacher, the most trusted and loved person in my life. Mr. Myrus was always perfectly dressed and spoke with the conviction that talking to small kids didn't mean that he had to sacrifice proper pronunciation or grammar. And he was demanding. Oh, he wasn't unreasonable or cruel; he simply felt that no matter what your best was, you should achieve it. As luck would have it, I met him again as my eighth grade math teacher. I was not, nor ever will be, gifted in math. And thirteen-year-old girls do not have the energy to devote to something like square roots . I remember our struggles, "I don't know the answer. I can't do it.!" "Perhaps you don't know the answer," he would say quietly. "Do you think we might figure it out together? How do you know what you can do until you try?" Mr. Myrus lived around the corner, and I would often stop by to talk while he worked in his wood shop. In this room of sawdust, wood chips, and the smoke from the woodburning stove, I felt respected and valued as a person. I knew there was someone who liked me for who I was, someone who, while he always wanted me to do my best, let me know that if I had really tried, that was enough. Mr. Myrus was my teacher and my friend. He taught me to be kind. He taught me my own value. He taught me about honor, about truth, and about doing my best--and that all feelings and beliefs have dignity and deserve respect. And of all the things I know, this I believe: We can't all be "the" best, but we can, each of us, be our best, and I know that's true because Mr. Myrus told me.
Question: When did Mr.Myrus first become the author's teacher?
Options: (A) When she was eight years old. (B) When she was in the fifth grade. (C) When she was thirteen years old. (D) When she was in the eighth grade.
Example Output: A

Example Input: Article: Plans to expand wind energy into the most scenic parts of Germany are meeting increasing opposition across the country. Anti-wind campaigners are angry that areas including the forests made famous by the tales of the Brothers Grimm are among the targets for new turbines . For the first time they have formed a national opposition group to _ the expansion. They say the expansion will damage forests and tourism across the country. Germany has started a massive expansion of renewable energy since the Fukushima nuclear disaster in 2011 in Japan. The government decided to reduce atomic plants and instead increase the opportunities for green power. As a result, solar farms, biogas plants and wind parks are booming. In 2013, 22% of Germany's electricity was generated by renewable energy. Wind has played a major part in this change, making up half of the renewable energy in 2013, and the public has been generally supportive. To date, a majority of the 23,000 wind turbines in the country have been built in the flat northern and eastern parts of the country. But now the focus of expansion is on the areas of dark forest in the central and southern areas of Germany. One such region is the Rheinhardswald in the northern part of the state of Hesse. This is the home of the magical tales of Sleeping Beauty, Rapunzel and others, made famous in the books of the Brothers Grimm. This scenic place is a magnet, attracting hundreds and thousands of tourists from all over the world. But now there are also plans to build up to 200 turbines in this scenic place! Ann-Kathrin Blankenberg is a PhD student and an opponent of the plans. "It is not because this is the area of Sleeping Beauty," she says, "I want the green movement, I want green technology, I don't want nuclear power--- but they should be made in the right way and not by destroying the forests." The campaigners argue that putting wind turbines in this area makes no sense. The wind speeds are low and the area is home to some extremely rare birds including the endangered black stork. Campaigners say building turbines here would be disastrous for the birds.
