Input: Consider Input: Article: Larry was on another of his underwater expeditions but this time, it was different. He decided to take his daughter along with him. She was only ten years old. This would be her first trip with her father on what he had always been famous for. Larry first began diving when he was his daughter's age. Similarly, his father had taken him along on one of his expeditions. Since then, he had never looked back. Larry started out by renting diving suits from the small diving shop just along the shore. He had hated them. They were either too big or too small. Then, there was the instructor. He gave him a short lesson before allowing him into the water with his father. He had made an exception. Larry would never have been able to go down without at least five hours of theory and another similar number of hours on practical lessons with a guide. Children his age were not even allowed to dive. After the first expedition, Larry's later diving adventures only got better and better. There was never a dull moment. In his black and blue suit and with an oxygen tank fastened on his back, Larry dived from boats into the middle of the ocean. Dangerous areas did not prevent him from continuing his search. Sometimes, he was limited to a cage underwater but that did not bother him. At least, he was still able to take photographs of the underwater creatures. Larry's first expedition without his father was in the Cayman Islands. There were numerous diving spots in the area and Larry was determined to visit all of them. Fortunately for him, a man offered to take him around the different Spots for free. _ The diving spots afforded such a wide array of fish and sea creatures that Larry saw more than thirty varieties of creatures. Larry looked at his daughter. She looked as excited as he had been when he was her age. He hoped she would be able to continue the family tradition. Already, she looked like she was much braver than had been then. This was the key to a successful underwater expedition.
Question: In what way was this expedition different for Larry?
Options: (A) His daughter had grown up. (B) He had become a famous diver. (C) His father would dive with him. (D) His daughter would dive with him.

Output: D

Input: Consider Input: Article: If you want to see climate change, head north and keep going until you run out of globe. That is easier said than done. The Arctic is home to few people and covered in ice much of the year. But those who make their way to the icy seas of the Arctic Ocean will see a part of the planet that is warming and changing faster than anywhere else. In September, scientists announced at the National Snow and Ice Data Center that Arctic summer sea ice had fallen to its second lowest level since 1979, and probably long before that. The Arctic has lost an area of ice greater than the area of all U.S. states east of the Mississippi River. And what ice remains appears to be getting thinner and weaker. Nick Toberg and Till Wagner are polar ice scientists who are doing sea ice fieldwork. "There is plenty of data to suggest that the ice is becoming thinner as well as smaller in area," they say. The changes happening in the Arctic are a warning for the entire world . As polar expert Walt Meier puts it, " _ Some scientists worry that Arctic sea ice may be going from a downward spiral to a "death spiral", one from which there is no escape. As more ice melts , more dark open water appears. The darkness absorbs more heat, which speeds up the pace of melting. Until recently, many scientists thought it might take until the end of the century for the North Pole to become completely ice free during the summer. Now some believe it could happen by 2030 or even earlier. "The melting is happening faster in the real world than it has in the models," says Nick Toberg.
Question: Nick Toberg may agree that _ .
Options: (A) the ice in the North Pole will stop melting (B) the ice in the North Pole is melting faster than expected (C) the ice in the North Pole will melt before 2030 or even earlier (D) the ice in the North Pole will not disappear until the end of the century

Output: B

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
