Read the following article and select the best answer. Article: Essay is optional and no penalties for wrong answers. These changes will take place in SAT college exam. The changes include the use of some words more commonly used in school and on the job instead of the words such as "prevaricator" and "sagacious". College Board officials said the change is needed to make the exam better representative of what students study in high school and the skills they need to succeed in college and afterward. The new exam will be rolled out in 2016, so this year's ninth graders will be the first to take it, in their junior year. The new SAT will continue to test reading, writing and math skills, with an emphasis on analysis. Scoring will return to a 1,600-point scale last used in 2004, with a separate score for the optional essay. For the first time, students will have the option of taking the test on computers. They also said many students who are terrified they will be tested on lots of SAT words currently can ask for help: practicing with flashcards. They know flashcards are not the best way to build real word knowledge that lasts, but when the SAT rolls around they become the royal road. Students stop reading and start flipping. The essay will be changed in other ways, too. It will measure students' ability to analyze and explain how an author builds an argument and it will also be up to colleges whether the essay will be required. Each exam will include a passage drawn from "founding documents": such as the Declaration of Independence or from discussions they've inspired. Instead of testing a wide range of math concepts, the new exam will focus on a few areas, like algebra, thought to be most needed for college and life afterward. A calculator will be allowed only on certain math questions, instead of on the entire math portion . Jim Rawlins, the director of admissions at the University of Oregon, said the changes will potentially help the students but it will take a few years to know its influence, after the students go on to college. He said some colleges are still dealing...

(Question)
Read the following article and select the best answer. Article: "How lucky you are to be a doctor..." Anyone who's a doctor is right out of luck, I thought. _ You may think I want to change my job. Well, at the moment I do. As one of my friends says-even doctors have a few friends-it's all experience. Experience! I don't need such experience. I need a warm, comfortable, undisturbed bed of my own. I need it badly. I need all telephones to be thrown down the nearest well, that's what I need. All these thoughts fly round my head as I drive my Mini through the foggy streets of East London at 3:45 a.m. on a December morning. I am a ministering angel in a Mini with a heavy coat and a bag of medicines. As I speed down Lea Bridge in the dark at this horrible morning hour, the heater first blowing hot then cold, my back aching from the car-seat, I do not feel like a ministering angel. I wish I were on the beach in southern France. Call me a bad doctor if you like. Call me what you will. But don't call me at half past three on a December morning for an ear-ache that you have had for two weeks. Of course, being a doctor isn't really all bad. _ . Once in a while people are ill, once in a while you can help, once in a while you get given a cup of tea and rock-hard cake at two o'clock in the morning-then you worry if you have done everything. But all too often 'everything' is a repetitious rule: look, listen, feel, tap, pills, injection, phone, ambulance, away to the next. And then there is always the cool, warm voice of the girl on the switchboard of the emergency bed service who will get your patient into hospital for you-the pleasant voice that comes to you as you stand in the cold, dark, smelly, dirty telephone box somewhere in a dangerous section of town. Oh, it has its moments, this life does. Question: According to the sentence "Anyone who's studying medicine should have his head examined," we know that _ . - a medical student should have a very good memory - a doctor must be mentally strong so that he can meet any difficult situation - the writer thinks that those who want to be doctors are crazy - to be a doctor is a challenge for people's mental health
(Answer)
the writer thinks that those who want to be doctors are crazy

Read the following article and select the best answer. Article: Everybody hates rats. But in the earthquake capitals of the world - Japan, Los Angeles, Turkey - rats will soon be man's new best friends. What happens after an earthquake? We send in rescue dogs. Why? Because they can smell people. Dogs save lives. They help rescuers to find living people. But dogs are big and they can't get into small spaces. So now a new research project is using a smaller animal to save lives: the rat. How does it work? First, the rat is trained to smell people. When this happens, the rat's brain gives a signal .This is sent to a small radio on its back, and then the rescuers follow the radio signals. When rat's brain activity jumps, the rescuers know that someone is alive. The rat has smelled that person. Although there are already robots which can do this job, rats are better. Christian Linster at Cornell University, New York, says, "Robots' noses don't work well when there are other smells around. Rats are good at that. " Rats can also see in the dark. They are cheaper and quicker to train than dogs, and unlike robots, they don't need electricity! The "rat project" is not finished, but Julie Ryan of International Rescue Corps in Scotland says, "It would be fantastic. A rat could get into spaces we couldn't get to, and a rat would get out if it wasn't safe." Perhaps for the first time in history, people will be happy to see a rat in a building(but only after an earthquake, of course.) Question: After reading the passage we can know _ . - at present rats have taken the place of dogs in searching for people - the "rat project" has been completed - people are now happy to see a rat in a building - now people still use dogs and robots in performing rescues
now people still use dogs and robots in performing rescues
