I'm taking a test and have to guess the right answer to the question after the article. Article: There is very simple way of measuring the height of a water-tower, which we cannot measure by climbing. Suppose, for example, that we wish to find out the height of the water-tower, AB, in a factory. We first of all go to where the water-tower is standing and measure a distance of, say, 25 feet from it. Then we take a stick, and stand it in the ground at the spot we have just marked. Let us suppose the stick we are using is 4 feet in height. We now walk farther away from the water -tower in the same straight line as when we measured off the distance of 25 feet. We go from the water-tower until we come to point E, where with our head on the ground, we see the top of the stick and the top of the water-tower in the same height line---that is, the top of the stick just covers the highest part of the water-tower. Every schoolboy can work out the height of the water-tower now. Suppose that the line CE is five feet. We know that the stick is 4 feet high and the distance BE is 30 feet. Thus, 5 is to 4 as 30 is to AB. Question: To measure a water-tower in this way, _ . Options: A: no tool is needed B: Besides a stick, tape-measure or at least a ruler is necessary. C: we have to use nothing but a stick D: we have to prepare a set of expensive tools

I'm taking a test and have to guess the right answer to the question after the article. Article: I am not just a successful architect . I also like to play the piano. In my spare time I often turn some dry musical symbols into beautiful music. Many years ago, while I was in a university studying architecture, I worked in a workshop. During the break I found an old piano in the corner of the room. With the allowance of the boss I sat down to have a try. Following my fingers the keys danced brilliantly and at the same time beautiful music flew out and then to every part of the room. All my workmates suddenly stopped talking and made their ears ready for my music. After graduation, I began to devote myself to my profession. All my musical talent was wasted into zero. Then one evening we went to a concert at which Mr. Stevenson, one of the ordinary workers in my company, sang us some beautiful songs. His musical talents made us all surprised. We all enjoyed ourselves with his beautiful voice so much that we even thought him a professional singer. I was also reminded of my musical talent. I began to train in a training center. My teacher was strict with me. He encouraged me to train every weekend and each time he asked me to play better than the last. Now I can proudly say I am also a successful pianist because every time I played on the stage fresh flowers and warm clapping would come from my audience. So I say, my friends, don't busy yourself with your work too much. Find some time to develop your potential talent and your life will become more wonderful. Question: After graduation, why did the author waste his music talent? Options: A: He realized that his music talent was nothing at all. B: His workmates did not like him to play music. C: He went on with his further study. D: He was too busy with his work.

I'm taking a test and have to guess the right answer to the question after the article. Article: It must have been around nine o'clock when I drove back home from work because it was already dark. As I came near to the gates I turned off the head lights of the car so as to prevent the beam from swinging through the window and waking Jack, who shared the house with me. But I needn't have done so. I noticed that his light was still on, so he was awake anyway--unless he had fallen asleep while reading. I put the car away and went up the steps. Then I opened the door quietly and went to Jack's room. He was in bed awake, but he didn't even turn towards me. "What's up, Jack?" I asked. "For God's sake, don't make a noise," he said. The way he spoke reminded me of someone in pain who is afraid to talk in case he does himself serious injury. "Take your shoes off, Neville," Jack said. I thought that he must be ill and that I had better give way to him to keep him happy. "There is a snake here," he explained. "It's asleep between the sheets. I was lying on my back reading when I saw it.I knew that moving was _ . I could not have moved even I'd wanted to." I realized that he was serious. "I was depending on you to call a doctor as soon as you came home," Jack went on. "It has not bitten me yet but I dare not do anything to upset it. It might wake up. I'm sick of this," he said."I took it for granted that you would have come home an hour ago." There was no time to argue or apologize for being late.I looked at him as encouraging as I could and went to telephone the doctor. Question: According to the passage, Neville should have been home at _ . Options: A: 7 p.m. B: 8 p.m. C: 9 p.m. D: 6 p.m.
