TASK DEFINITION: In this task, you're given an article, a question which often contains a blank, four options (associated with "A", "B", "C", "D") and the answer to that question. Your task is to classify whether the given answer is correct or not by providing "Yes" or "No", based on the article.
PROBLEM: Article: How do people traditionally manufacture things? They usually start with a sheet of metal, wood or other material and cut, drill and shave it to create a desired shape. Sometimes, they use a mold made of metal or sand, pour liquid plastic or metal into it and let it cool to create a solid part. Now, a completely different method is gaining popularity. On Oct. 9, 2013, London Science Museum kicked off its new exhibition, 3-D: Printing the Future, with over 600 3-D printed objects on display, including space probes , toy dolls and even human organs - basically any product you can think of, reported Live Science. You might find it hard to believe that an object can actually be "printed out" like a picture. But it is not that hard to understand how it works. Just as a traditional printer sprays ink onto paper line by line, modern 3-D printers spread material onto a surface layer by layer, from the bottom to the top, gradually building up a shape. Instead of ink, the materials the 3-D printer uses are mainly plastic, resin and certain metals. The thinner each layer is - from a millimeter to less than the width of a hair - the smoother and finer the object will be. And objects always come out in one piece, sparing you the trouble of putting different parts together afterward. For example, 10 years ago a desktop 3-D printer might have cost PS20,000 (200,000 yuan), while now it costs only about PS1,000, according to the BBC. In fact, 3-D printers have been around for some time, but until recently they hadn't been very popular since few people could afford them. Last year, though, saw a big decrease in the price of 3-D printers. However, as 3-D printing technology becomes more commonplace, it may trigger certain problems. One of them is piracy . "Once you can download a coffee maker, or print out a new set of kitchen utensils on your personal 3-D printer, who will visit a retail store again?" an expert on 3-D printing told Forbes News. Even more frightening, the world's first 3-D printed gun was successfully fired in the US in May of this year, which means that 3-D printing could potentially give more people access to weapons.
Question: According to the article, in the future, 3-D printing technology will probably _ .
Options: (A) change the way people make products (B) be applied as widely in our daily lives as computers (C) forbid many countries to make purchases of weapons (D) take the place of normal printers and save lots of energy
Asnwer: A

SOLUTION: Yes

PROBLEM: Article: Reading can be a social activity. Think of the people who belong to book groups. They choose books to read and then meet m discuss them. Now, the website BookCrossing.com rums the page on the traditional idea of a book group. Members go on the site and register books they own that they would like.sham. BookCrossing provides an identifying numb" .stick inside the book. Then the person 'releases' the book by leaving it in a public place. The hope is that the book will have an adventure, traveling far and wide with each new reader who finds it. Bruce Pederson is the chief executive of BookCrossing. He and his wife Hearer started the site with Ron Hombaker in 2001. Mr. Pederson says, "One of the founding principles was the two things that change your life: tha people you meet and the books you mad. BookCrossing combines both." Members leave books on park beaches and buses, in train stations and coffee shops BookCmssem hope that whoever finds their book will go m the site and record where they found it. People who find a book can also leave some renurks describing what they thought of it. E-mails are then sent to the BookCrossers to keep them updated. Pederson says the idea is for people not to be selfish by keeping.book to gather dust on a shelf at home.He says."BookCrossing is a tool that allows you to uniquely identify your book and follow it on its journey. We all have this life-changing literature that we tend to keep on our shelf and BookCrossing encourages its members to read and release and out be 'shelf-ish'. The read and release idea of BookL1essing has spread.The site now has more than one million members in more than 135 cwrntries.
Question: What should a member do first before releasing a book?
Options: (A) Register the back online. (B) Leave the book in a coffee shop. (C) Stick an identifying number on it. (D) Remind~m read it.
Asnwer: D

SOLUTION: No

PROBLEM: Article: It is hardly surprising that clothing manufacturers follow certain uniform standards for various features of clothes. What seems strange, however, is that the standard adopted for women is the opposite of the one for men. Take a look at the way your clothes button. Men's clothes tend to button from the right, and women's from the left. Considering most of the world's population--men and women--are right-handed, the men's standard would appear to make more sense for women. So why do women's clothes button from the left? History really seems to matter here. Buttons first appeared only on the clothes of the rich in the 17thcentury, when rich women were dressed by servants. For the mostly right-handed servants, having women's shirts button from the left would be easier. On the other hand, having men's shirt button from the right made sense, too. Most men dressed themselves, and a sword drawn from the left with the right hand would be less likely to get caught in the shirt. Today women are seldom dressed by servants, but buttoning from the left is still the standard for them. Is it interesting? Actually, a standard, once set, resists change. At a time when all women's shirts buttoned from the left, it would have been risky for any single manufacturer to offer women's shirts that buttoned from the right. After all, women had grown so used to shirts which buttoned from the left and would have to develop new habits and skills to switch. Besides, some women might have found it socially awkward to appear in public wearing shirts that buttoned from the right, since any one who noticed that would believe they were wearing men's shirts.
Question: What is surprising about the standard of the clothing industry?
Options: (A) It has been followed by the industry for over 400 years. (B) It is different for men's clothing and women's. (C) It works better with men than with women. (D) It fails to consider right-handed people.
Asnwer: B

SOLUTION:
Yes
