One hundred years later, on the appointed day, 300 people gathered to watch the opening of the box. Many in the crowd were the descendants of people who had placed things inside the box. When the box was opened after midnight, the things inside the box were in very good condition. There were newspapers, photos, diaries, name cards, family trees, books and lots of letters, including one written by Theodore Roosevelt, who became the President of the USA later that year. One of Roosevelt's friends lived in Colorado Springs at that time. Many of the letters were written to their descendants. They describe the hopes that the people of 1901 had for the people of the next century. At that time, Colorado Springs had just a few thousand people. Now nearly half a million people live there.

Question: Write a multi-choice question for the following article, with the given choices and answer: Article: It was midday when I got the call that my grandfather was not well and he was quickly getting worse. My family did not know how long he would stay in the world. I knew I had to get to the hospital to tell him how much I loved him. As I drove to the hospital, I pictured him before I got to tell him how much he meant to me. Trying to fight back the tears, I wanted to stay calm when I saw him. When I got to the hospital, I hurriedly looked for his hospital room. I found him in a semi-conscious state . On my knees, I said softly, "Hello, Grandpa." Still feeling shy, I decided not to leave his bedside without letting him know. While I asked about how he was, he told me, "I'll be fine, Henry." although we both knew that wasn't true. Then he asked me with a smile how I was doing. Hearing what my grandpa said, I was much moved. I made the decision that I had to show my _ for him. As I found all the courage I had, I hold his hand tightly. I cried out, "Grandpa. I just want to let you know how much I love you. I hope you already know that yet I just want to make sure." By this time, tears were rolling down my face. All those years of love that I had shut and not let him know, became free. Smilingly, he said, "I know. Thank you for telling me that. All I have on this planet is my family and my love for them. If there is anything I could ask of you, I want you to be good to your family, your mother, your father, and your brother. That's all I want of you." What I learned that day changed my whole life. From then on, I began telling people how much I love them, care for them, and respect them. I get in touch with, for example, my babysitter, my barber, to show my appreciation. I go down into the city once a week and serve pizza to the homeless. I wake up every morning and list everything I'm thankful to in my life.

Write a multi-choice question for the following article, with the given choices and answer: Article: Is your TV connected to the Internet? What about your chair, or your fridge? Probably they are not. But in the future, most things in your home may be connected, thanks to the so-called "Internet of things". The Internet of things may be coming sooner than you think. Earlier this year, Samsung CEO spent a lot of time talking about the Internet things. He said that four years from now, every Samsung product will be part of the Internet of things, no matter whether it's a remote control or a washing machine. So, how do household objects that are part of the Internet of things work? Well, think of a common chair. When connected to the Internet, the chair warms up when it knows the user has just walked into the room and is feeling cold. An Internet-connected camera could help people feel safer in their homes. It can know people's faces and has an infrared sensor , so even if it's dark it can see when someone passes by and send you a message on your smartphone to let you know who's there. If the person is someone you don't know, it can tell you that, too. But according to MIT Technology Review, whether companies are connecting dog food bowls or security systems to the Internet, there may be some problems. For example, many early connected-home objects don't have much built-in security, which means they could be hacked. Moreover, it could be difficult to get these new machines to work together especially when they are made by different companies. To fight this, many companies have joined the Open Interconnect Consortium, which had 45 members by late 2015. So, picture this: you enter your home.The temperature changes to make you feel comfortable. Your favorite music starts playing for you. Do you think that this would be a good thing? It may happen sooner than you think.[:] Options: A Advantages of living with the Internet B Disadvantages of living with the Internet C The coming "Internet of things" D The impossible "Internet of things" Answer: C The coming "Internet of things" Question:
