Ques: I'm taking a test and have to guess the right answer to the question after the article. Article: Do you know electricity can change the way we taste food?Proving this fact is a revolutionary electric fork designed by Japanese researchers that can make any dish taste salty. According to Hiromi Nakamura,a Post Doc Research Fellow at Tokyo's Meiji University,the technology can be very useful for people on special diets.Patients with high blood pressure,for instance,can easily go on a low-salt diet and still enjoy delicious food.And with the fork,there's  ly no risk of over-salting their food.Luckily,the voltage  is so small that there is no risk of electrocution  either. The idea of adding electricity to food was first exposed as an experiment at the Computer Human Interaction Conference in Austin,Texas,in 2012.Nakamura and her team connected a wire to a 9-volt battery and passed it through a straw placed in a cup of sweet lemonade.Volunteers reported that the charged lemonade tasted'blander',because the electricity created the taste of salt. Nakamura has improved the technology to be able to transfer an electric charge to food through forks and chopsticks."The metallic part of the fork is one electrode ,and the handle is the other,"Nakamura explained."When you take a piece of food with the fork and put it in your mouth,you connect the circuit.When you remove the fork from your mouth,you disconnect the circuit.So it actually works as a switch." Simon Klose,host of food program Munchies,who recently visited Nakamura to try out the fork himself,called this form of'food hacking'one of the greatest eating experiences he'd ever had. "When I first heard of electric food,it sounded scary,"he said.He later continued to use a charged fork to eat pieces of fried chicken,and found that the saltiness considerably increased as the electricity was connected. Nakamura has been eating'electric'food for the past three to four years in an attempt to understand it better."For me,'food hacking'is about strengthening or weakening real food,"she said."It may seem like we're cooking but we're actually working on the human senses." Question: The electric fork may benefit people who  . Options: A: need to go on a diet B: have high blood pressure C: prefer food free of salt D: show interest in tasty food
Ans: B

Ques: I'm taking a test and have to guess the right answer to the question after the article. Article: A "blogger" is a person who writes on an Internet website called a "blog". The word "blog" is a short way of saying "web log", or "personal website". Anyone can start a blog, and they can write about anything they like. There are millions of blogs on the Internet today. They provide news, information and ideas to the people who read them.They contain links to other websites.And they provide a place for people to write their ideas and react to the ideas of others. A research company called Perseus has studied more than 3,000 web logs. It says that blogs are most popular with teenage girls. They use them to let their friends know what is happening in their lives. The study also says that more than 100,000 bloggers stopped taking part in the activity after a year. However, some people develop serious blogs to present political and other ideas. For example, the Republican and Democratic parties in the southern state of Kentucky recently started their own blogs. And American companies are beginning to use blogs to advertise their products. At thesame time, some long-standing blogs have ended. Last week, blogging leader Dave Winer closed his free blog service "weblogs.com". He said the site became too costly to continue. He started the blog four years ago, and thousands of people had written on it. They are now upset because they did not know that the site was closed. One blog that is still going strong is called Rebecca's Pocket.Rebecca Blood created the website in 1999. She wrote about the history of blogs on the site.That article led to a book called The Weblog Handbook.It has been translated into four languages so far. Miss Blood says Rebecca's Pocket gets about thirty thousand visitors a month.She writes about anything and everything ---- politics, culture and movies. She recently provided medical advice. And she wrote about how to prevent people from being stolen from online bank accounts. Question: Which of the following statements is NOT true according to the text? Options: A: Politicians don't use blogs at all. B: A lot of bloggers no longer write or read blogs. C: Those who like to use blogs are mostly teenage girls. D: Dave Winer closed his "weblogs.com" because of the money shortage.
Ans: A

Ques: I'm taking a test and have to guess the right answer to the question after the article. Article: Going whitewater rafting in North Carolina (N.C.), you are cutting bonds to the every-day troubles and for a short time you are back in the natural world with your co-travelers. Rafting in N.C. has the added benefit of a long, warm rafting season, beautiful scenery, and amazing history. Only twenty minutes from Asheville, N.C., whitewater rafting on French Broad River in N.C. still has the flavor wilderness and adventure. Half Day Trip: This N.C. whitewater rafting trip begins at Barnard and finishes at Stackhouse. Typical time on the river is 1.5 to 2 hours. A couple of factors that affect the time on the river are the size of the trip and the level of the river. A small trip at high water will move faster downstream than a larger trip at lower levels. $44.00 per person.
