Read the following article and select the best answer. Article: Warm water freezes more quickly than cold water. Sir Francis Bacon said that almost four hundred years ago. But few people believed him until 1970. In that year Canadian scientist Geoge Kell proved the English physicist was right. Dr Kell filled one open bowl with cold water. He filled another with warm water. He put both bowls to the same low temperature. The warm water froze first. The lack of covers on the bowls was the secret . Some of the warm water changed into vapor. It evaporated into the air. This meant that less of the warm water was left to freeze. And so the warm water froze faster than the cold water. Question: Most people didn't believe Bacon because warm water is _ . - further from freezing temperature than cold water - quicker to evaporate than cold water - able to flow faster than cold water - a little harder than colder water
further from freezing temperature than cold water

Read the following article and select the best answer. Article: Dear Editor, I'm now busy in preparing for the Postgraduate Entrance Exam. A few days ago, I happened to see some new guidebooks for those who want to take next year's exam. With too many hopes and without taking it into too much consideration, I bought several that were written by some known for helping candidates for master's degrees. What made me really angry was the starting discovery that the contents of those books were almost exactly the same as some I had bought before. There were only superficial changes in their covers, with more attractive new titles and better designs. The contents were the same. People say that the publishing industry is in a state of chaos these days but I used to be doubtful abut that. I was of the opinion that only people of noble character, prestige , and exceptional talent would produce books for higher education. But these editors are caring little about their readers. I hope that authors and publishing houses will be more responsible for their readers. Don't destroy the image that you have with your readers. Question: The writer was angry because _ . - there were a lot of printing mistakes in the books that he had bought - the books were so expensive that he couldn't afford any of them - he found the books he had bought were thin but of poor quality - the books had the same contents as what he had bought before
the books had the same contents as what he had bought before

Q: Read the following article and select the best answer. Article: If you have seen or heard of the British TV series Downton Abbey, you have probably noticed an "upstairs-downstairs" class system in which the noble people are upstairs, worrying what clothes they should wear for dinner and the poor people are downstairs, working hard to make food and tea. So it's not hard to tell that people are divided into different classes. British society has changed a lot since the days of Downton Abbey, but the division still exists and the funny accents do, too. Nowadays, what divides Britons is the so-called "North-South divide". As you make your way north from the south coast of England, the accent begins to change. The posh "How are you" in parts of the South becomes "Ahhdu" (how do you do) in the Midlands, "reeit" (are you all right) in the North West, "eyyup" (what's up) in Yorkshire, and "hou's it gaun" (how's it going) in Scotland. Besides accents, the economy also changes. The rich southern city of London slowly becomes the North where people general have less money. So where does the "South" stop being the "South" and the "North" start being the "North"? Well, depending on where someone comes from in Britain, you'll get a different answer. "Anywhere above London is 'the North'," you might hear a Londoner say. Or if you're in Scotland, you might hear, "Southern softer!", talking about a person from Lancashire or Yorkshire, who think of themselves as "hard (tough) Northerners". "Anywhere south of Manchester is not northern," you might hear a person from Manchester say. Many stereotypes have come from the "North-South Divide", too. Often, southerners are seen as being rude and snobbish by northerners. And northerners are often seen as uneducated by southerners. Today, the career you have and the person you marry don't depend on where you were born or what class you are from. But as London is getting richer and people are moving to the South for work, the North-South divide is getting bigger. Yet for all that divides us, the truth is, we couldn't live without each other! Question: What is the passage mainly talking about? - British accents are different from North to South. - Class division is getting smaller at present. - It is about the "North-South Division" and its influence. - Northerners and Southerners dislike each other in Britain.
A: It is about the "North-South Division" and its influence.
