Article: It is believed that it took about 800 thousand to 1 million years for the earth's population to reach the 250 million total which existed at the end of the first century AD. For some time after that, disease, famine and war kept the population increase down to a rate of 1 percent a year so that more than 15 centuries passed before the population reached 500 million. But in the next 250 years, up to 1850, the population of the world shot to 1 billion and today it has reached 3.5 billion. Scientists say that in the next 35 years the population of the world will double, reaching almost 7 billion by the year 2010. When experts are asked what are the most effective measures that can stop over population, they reply that at least three measures can be considered. (A) Increasing sources and supply of food for under-developed countries. (B) Increasing the industrialization of under- developed countries. (C) Controlling birth. The experts add, however, that none of the above measures can be effective by itself, and that all must be combined into one whole program. They also agree that without controlling of births, any other measures are doomed to failure. Question: The population _ because of disease, famine and war. Yes or no, is the answer "increased slowly"?
No

Article: Store shelves are filling up with so-called "green" products promising to benefit the environment. A recent argument shows that it can be as difficult for buyers to confirm such statement as for producers to defend them. The argument concerns the GreenPlug Electricity Saver. The GreenPlug is supposed to prevent energy waste by electrical equipment whose constant -speed motors operate at less full load---as is especially true of older refrigerators. Research showed that such motors can be made to do the same work with less heat, noise, and power consumption just by lowering the voltage of the power supply. John and Wyck Hay, started Green Technologies to apply that finding to home appliances. In the USA, there are more than 140 million refrigerators in use, accounting for an average of 16% of the household electric bill. Two years of research resulted in the GreenPlug. Connecting between wall socket and refrigerator, the equipment contains a minicomputer that gives a motor full power (120 volts on average) for start-up, then reduces the power to 106 volts. Older refrigerators are the most overpowered and, thus, save the most energy with a GreenPlug. Refrigerators less than two years old are already energy-saving that a GreenPlug actually makes them waste electricity. The higher the voltage, the larger the difference a GreenPlug makes. Higher power costs shorten the payback time. The population-weighted national average is 10 cents per kilowatt-hour. But some residents in Washington State pay 1.5 cents. Some in Alaska pay 41.6 cents. Then come highly individual household differences like the number of children or refrigerator -opening age. All in all, the GreenPlug should save the average consumer $20 a year. Although the GreenPlug lowered the voltage as it was designed to do,Consumer Reports, an influential magazine, questioned how quickly---if ever---electricity savings due to the plug would repay its cost. People would be better off buying a new, high-efficiency refrigerator, the magazine... Question: In the GreenPlug argument, the magazine Consumer Reports _ . Yes or no, is the answer "doubts the effect of the GreenPlug"?
No

Q: 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: With which of the following statement would Barry Brown most likely agree? Yes or no, is the answer "Drivers, GPS systems and passengers should unite to improve GPS systems."?
A: No
