Read the following article and select the best answer. Article: Windsurfing is a sport that combines sailing and surfing.In 1948,twenty-year-old Newman Darby first thought of using a handheld sail to contro1 a small boat.Darby did not apply for a patent for his design at first.However,he is recognized as the inventor of the first sailboard. Californians Jim Drake,a sailor and engineer,and Hoyle Schweitzer,a surfer and skier received the patent for a sailboard.They called their design a windsurfer.The early windsurfer boards measured 3.5 meters long and weighed 60 pounds.Later in the l980s,Newman Darby did apply for and receive a design patent for a one--person sailboat. In the late l940s,Newman Darby found he could control a 3-meter-long sailboat and make turns even without a rudder .In l964 he designed the first universal joint to go along with a flat bottom sailing boat.This sailboard was equipped with a universal joint,a board and a kite--shaped free sail and thus windsurfing was born. Naomi Darby,Newman's wife,was the first woman windsurfer and helped her husband build and design the first sailboard.She sailed while standing up,controlling the boat without the use of a rudder.She tilted the sail to change directions.This was something that had never been done before. Hoyle Schweitzer began producing sailboards in the early 1970s.The sport became very popular in Europe.By the late 1970s,windsurfing fever had Europe firmly in its grasp with one in every three families having a sailboard. The first windsurfing world championship was held in 1973.Windsurfing first became an Olympic sport for men in l984 and for women in l992. Question: Jim Drake and Hoyle Schweitzer received the patent for the design of _ . - a sailboard called windsurfer - a kite--shaped free sail - the first universal joint - a one--person sailboat
a sailboard called windsurfer

Read the following article and select the best answer. Article: The "Neighborhood Watch" scheme all started a few years ago in the quiet village of Mollington after a number of burglaries in the village and the surrounding area. The villagers came up with the idea that they themselves could keep an eye on their neighbors' possessions while they were away on holiday. Since then, and with the support of the government and police, more than 50,000 "Neighborhood Watch" schemes have been set up all over the country. The object of each "Watch" group is to reduce the opportunities that criminals have in any particular street or area. Each villager who is a member of the scheme will call the police whenever they see something suspicious. It is the police who actually check out each report and look into what is happening. Villagers who are part of the "Watch" are not supposed to act as police or put themselves in danger. When a new "Neighborhood Watch" scheme is set up in an area, one benefit is that most burglars dare not take a chance on breaking into someone's house because they know that there is a high risk of being seen by neighbors keeping a lookout. Burglars also know that people are more likely to have fitted good locks to their doors and windows. Another benefit is that, since the "Neighborhood Watch" schemes came into existence, there is growing evidence of a new community spirit. It is bringing people together as never before, and encouraging people to care for each other. New friendships are being made, and contact is often established with old people living on their own, who are often the most frightened and the most at risk. Question: When a new "Watch" scheme starts in an area _ . - the police send fewer officers to the area - villagers put signs on the indoors - burglars are less likely to break into houses - people fit new locks to their doors and windows
burglars are less likely to break into houses

*Question*
Read the following article and select the best answer. Article: Electricity bills can be highly expensive and the power we consume comes at an even greater cost to the environment when you consider that over 85% of the electricity produced in the United States comes from fuels. Whether you're concerned about cleaning up the environment or you simply want to reduce your electricity bill,residential wind power generators could be a solution. Producing wind power at home will not work for everyone. If you live in a over-populated residential area,there may be certain laws and zoning requirements that prohibit the use of windmills .If you live on 1 acre of land or more,you probably won't have any issues but you should investigate carefully to make sure that wind power generators are both legal and practical where you live. Even if there are no laws or regulations prohibiting wind power generators you still need to be in a location that gets enough wind on a regular basis. Some producers of wind generators recommend that you live in an area with wind speeds that average at least 10 mph. Newer models have been developed recently that can operate with wind speeds as low as 4 mph but maximum efficiency is achieved at higher wind speeds. Before you fix a wind powered system,you will have to determine your power requirements. Will you be using it to charge a small battery for a boat or vehicle or will you need enough power to run your entire household and be completely off the grid ?Once you know what your power requirements are,you can start shopping around for a system that can meet those needs. Wind power generators are a great solution for a lot of people.They're an ideal solution for remote locations where it would be impractical or simply too expensive to tap into the grid.They are quiet and totally clean,producing no pollution. They require no fuel and very little maintenance. Residential wind power offers a lot of benefits but it's not for everyone. You'll have to have some money up front to pay for the system and equipment;however,you could save quite a bit of money if... Question: What can we infer from the passage? - wind power generators enjoy a lot of benefits. - you can place wind power generators wherever you want. - wind power generators are affordable to most families. - wind power generators are an ideal solution for everyone.
**Answer**
