Q: I'm taking a test and have to guess the right answer to the question after the article. Article: Edmund Halley was an English scientist who lived over 200 years ago. He studied the observations of comets which other scientists had made. The orbit of one particular comet was a very difficult mathematical problem. He could not figure it out. Neither could other scientists who dealt with such problems. However, Halley had a friend named Isaac Newton, who was a brilliant mathematician. Newton thought he had already worked out that problem, but he could not find the papers on which he had done it. He told Halley that the orbit of a comet had the shape of an ellipse . Now Halley set to work. He figured out(,)the orbits of some of the comets that had been observed by scientists. He made a surprising discovery. The comets that had appeared in the years 1531, 1607, and 1682 all had the same orbit. Yet their appearance had been 75 to 76 years apart. This seemed very strange to Halley. Three different comets followed the same orbit. The more Halley thought about it, the more he thought that there had not been three different comets as people thought. He decided that they had simply seen the same comet three times. The comet had gone away and had come back again. It was an astonishing idea! Halley felt certain to make a prediction of what would happen in the future. He decided that this would appear in the year 1758. There were 53 years to go before Halley's prediction could be tested. In 1758 the comet appeared in the sky. Halley did not see it, for he had died some years before. Ever since then that comet had been called Halley's comet, in his honor. Question: This passage in general is about _ . Options: A: Halley and other scientists B: the orbit of a comet C: Newton and Halley D: Halley and his discovery
A: D

Q: I'm taking a test and have to guess the right answer to the question after the article. Article: It is true that shyness can be a disadvantage socially for those who suffer from it seriously. I mean real shyness, not somebody who is simply quiet. Quiet people could be shy, but on the other hand, they may just be observing because they are unsure of you or others in your company. They may be capable of being extrovert and sociable, but on some particular occasions, they are quiet. I have learnt from my experience that those who observe and listen more and talk less can gain a position of strength. This means that even a very shy person, the type who is reluctant to talk in company , especially new company, can become a strong person in just about anything they choose. Remember, knowledge is power, and a shy introvert is in a better position to gain knowledge than an extrovert. Introverted people can give great attention to learning, and as good listeners they can take in an enormous amount from others. Over time, people can come to respect them far more than the extrovert who speaks a lot. Usually about themselves. What does it take , then for a very shy person to be that successful person they have always wanted to be ? They may only need one more thing to push themselves on their way. They need to dare themselves to take the leap; and when they do , they will probably find all the knowledge they have gained over the years will help them on their way to the top in their chosen field. Question: According to the author, introverted people can be successful because they usually _ . Options: A: have a strong will B: talk less and show off less C: learn more than extroverts D: have a good attitude to learning
A: C

Q: I'm taking a test and have to guess the right answer to the question after the article. Article: Imagine that the genome is a book.The book consists of 23 chapters with thousands of stories made up of paragraphs, words and letters on different levels.There are one billion words in the book, as long as 800 Bibles; if I read the genome out to you at the rate of one word per second for eight hours a day, it would take me centuries; if I wrote out the human genome, one letter per millimeter, my text would be as long as the River Danube.This is a huge volume, a book of great length, but it all fits inside an extremely small cell nuclear that fits easily upon the head of a pin. The idea of the genome as a book is not, strictly speaking, even a metaphor.It is true to a great extent.A book is a piece of digital information, written in one-directional form and defined by a code that translates a small alphabet of signs into a large dictionary of meanings through the order of their groupings.So is a genome.The only difference is that all English books read from left to right, while some parts of the genome read from left to right while some from right to left, but never both at the same time. While English books are written in words of different lengthens using twenty-six letters, genomes are written entirely in words of three-letter length, using only four letters, and instead of being written on flat pages, they are written on long chains of DNA molecules . The genome is a very clever book, because in the right condition it can both photocopy itself and read itself. Question: The real purpose of the author's comparison of the genome to a book is _ . Options: A: to focus on the differences between the two B: to lay emphasis on the similarities between the two C: to simplify the concept of the human genome D: to give an exact description of the human genome
A: C
