Your task is to find the correct answer (from the given options) for the question from the given article and return one of the options from "A", "B", "C", and "D". Do not generate anything else apart from one of the following characters: "A", "B", "C", "D". There is only one correct answer for each question.

Input: Consider Input: Article: As part of an effort to improve treatments for life-threatening illnesses, a team of scientists have created rabbits that glow in the dark. The efforts have produced two rabbits out of a litter of eight that went from being a normal, soft white to glowing green in the dark. The rabbits were born at the University of Istanbul as part of the cooperation between scientists from universities in Turkey and Hawaii. The rabbits glow to show that a genetic operation technique can work efficiently. "The green is not important at all--it's just a marker to show the experiment can be done successfully," said University of Hawaii associate professor, Stefan Moisyadi. To produce the glowing effect, researchers injected jellyfish DNA into a mother rabbit's embryos. Then those embryos were put into the mother. Similar experiments have resulted in glowing cockroaches and cats. Eventually, the researchers hope the technique can lead to new ways to produce medicines, Moisyadi said. "The final goal is to develop animals that are able to produce beneficial molecules in their milk that can be cheaply extracted , especially in countries that cannot afford big factories that make drugs, which usually cost US$1bn to build. Then they will be able to produce their own protein-based medication in animals," Moisyadi said. The rabbits are expected to live as long as non-glowing rabbits, but Moisyadi said he understands people can object to this kind of experimentation involving live animals. "To the people against, I say: think, what are the benefits and what is the harm?" Moisyadi said. "And if the benefits outweigh the harm, let's go with the benefits." Moisyadi started developing the project in 2006, and researchers are now waiting to see if pregnant sheep produce similar results.

Options: (A) Their fur became green after the experiment. (B) They were chosen from a special species of rabbits. (C) The color1 that they glow isn't of interest to scientists. (D) They live shorter lives than ordinary rabbits.

Output: C

Input: Consider 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.

Output: A

Input: Consider Input: Article: In the past, American families tended to be quite large. Parents raising five or more children were common. Over the years, the size of the family has decreased. One reason for this is an increase in the cost of living. On the average, children attend schools for more years than they used to, making them financially dependent on their families longer. Moreover, children nowadays are better dressed and have more money to spend on entertainment. The parents usually take the responsibility for all the expenses. Meanwhile, families are less close than they used to be. More and more American mothers work away from home. The break up of the family occurs when the parents divorce. A lot of children in the U. S. live part of their young lives with only one parent. Broken families usually result in problems for children and parents alike. Children blame themselves when their parents separate. They grow up feeling unsettled as they are moved back and forth between parents. Usually one parent is responsible for raising the children. These single parents must care for the children's emotional and psychological needs while also supporting them financially. This is very demanding and leaves very little time for the parent's own personal interests. Single parents often marry other single parents. In this type of family, unrelated children are forced to develop brother or sister relationship. The situations of many American families today are not good. However, recent signs indicate that things are getting better. The divorce rate is declining. The rate of childbirth is rising. Perhaps Americans have learned how important families are.
