Ques:Read the following article and select the best answer. Article: prefix = st1 /Massachusetts today looks nothing like it did when the first English settlers arrived. Back in the 17th century, forest blanketed the land. Today, roads and towns cover much of the area. But the past is not dead and gone. Just an hour's drive from Bostonlies Plimoth Plantation . There you'll experience the 17th century life from the days of the Pilgrims . You can look in the Pilgrims' homes, watch the way they cook, and ask them about their daily lives. You can even help them build houses or work in the fields. When you arrive at Plimoth, you are greeted with "How do you fare?" instead of "How are you?" In this living history plantation, actors portray real people of 17th-century Plymouth. Each actor has taken the identity of someone from that period. All the actors speak the language of Shakespeare. They're happy to talk about the hardships of their lives or just share the gossip of the day. But don't try to discuss modern topics. They won't understand what you are talking about! In fall, you can enjoy a harvest dinner very similar to the first Thanksgiving. You'll dine with your hands like Pilgrims. You'll find no pepper on the table. This expensive spice was used only sparingly in cooking. You'll find no last-course "dessert," either. At the time, people ate sweet dishes right along with the meal. Cranberries were on the menu then and still are today. A short distance from Plimoth, you can visit Cranberry World. At this unique museum, you'll see how cranberries are harvested and can taste different cranberry products. Of course, the first Thanksgiving included not only the Pilgrims, but also their Wampanoag guests. If you want to find out something about the Wampanoag, explore a re-created Wampanoag HomeSite. It is just a short walk from Plimoth. Step into the Native American home and enter a different world. Native Americans dressed in 17th-century Wampanoag outfits describe how their people lived 400 years ago. Outside, you can help make a traditional boat or learn about native... Question: The purpose of the rebuilt Wampanoag Homesite is _ . - to protect Native Americans, the Wampanoag - to attract more tourists to stay in Plimoth - to show how the Wampanoag helped the Pilgrims - to keep the 17th century Naive Americans live alive

Ans:to keep the 17th century Naive Americans live alive

Ques:Read the following article and select the best answer. Article: Nanotechnology is a fashionable word these days. The name "nano" comes from the size of molecules, which are measured in nanometers--or one billionth of a meter. Through operating the atoms and molecules, scientists can change the nature of common materials and even create new materials that have new properties. But scientists are concerned about its possible risks to our daily lives. Clothing merchants claim their nanocloth keeps our bodies warmer in winter, saving us from needing thick coats. Vitamin companies boast their nanopills are easier to absorb. Home decoration companies suggest you use their nanopaint, which has no smell, is waterproof, and free from poisonous substances. Nanomaterials are making our lives better, its creators say. The US National Science Foundation predicts nanotechnology research will grow into a US $-trillion industry over the next 10 years. But ly little is known about the potential health and environmental effects of the tiny particles. Just atoms wide, they are small enough to penetrate cells easily in lungs, brains and other organs. US bestseller "Prey", written by Michael Crichton, paints a doomsday in which a group of tiny nanomachines escapes the lab and threatens to take control of humanity. Studies have shown that some nanoparticles can be poisonous to animal cells. There are fears that exposure can cause breathing problems, since nanoparticles could be taken in through the nose, causing unknown problems to brain cells. Scientists also fear that nanoparticles placed on the skin could damage DNA. "No one knows, and that's the problem," said Pat Mooney, director of the ETC Group. "People are rubbing them on the skin as sunscreens and as cosmetics." Mooney's group is calling for products such as sunscreen, that are directly absorbed into the body to be _ taken _ off _ the _ shelf until they're proved safe. Question: What benefits can nanotechnology bring to us except _ . - It can allow us to be free from thick coats by wearing clothes made of nanocloth. - It can allow us to create more new materials to meet the need of our modern society. - It can help us to take control of the doomsday. - It can help us to decorate our homes more environmentally friendly.

Ans:It can help us to take control of the doomsday.

Ques:Read the following article and select the best answer. Article: Global Positioning Systems are now a part of everyday driving in many countries. These satellite-based systems provide turn-by-turn directions to help people get to where they want to go. But, they can also cause a lot of problems, send you to the wrong place or leave you completely lost. Many times, the driver is to blame. Sometimes a GPS error is responsible. Most often, says Barry Brown, it is a combination of the two. We spoke to Mr. Brown by Skype. He told us about an incident involving a friend who had flown to an airport in the eastern United States. There he borrowed a GPS-equipped car to use during his stay. Barry Brown: "And they just plugged in an address and then set off to their destination. And, then it wasn't until they were driving for thirty minutes that they realized they actually put in a destination back on the West Coast where they lived. They actually put their home address in. So again, the GPS is kind of 'garbage in garbage out'." Mister Brown says this is a common human error. But, he says, what makes the problem worse has to do with some of the shortcomings, or failures, of GPS equipment. Barry Brown: "One problem with a lot of the GPS units is they have a very small screen and they just tell you the next turn. Because they just give you the next turn, sometimes that means that it is not really giving you the overview that you would need to know that it's going to the wrong place." Barry Brown formerly served as a professor with the University of California, San Diego. While there, he worked on a project with Eric Laurier from the University of Edinburgh. The two men studied the effects of GPS devices on driving by placing cameras in people's cars. They wrote a paper based on their research. It is called "The Normal, Natural Troubles of Driving with GPS." It lists several areas where GPS systems can cause confusion for drivers. These include maps that are outdated, incorrect or difficult to understand. They also include timing issues related to when GPS commands are given. Barry... Question: What is Mr. Brown's attitude towards GPS? - Unconcerned - Prejudiced - Objective - Critical

Ans:
Objective
