Q: Write a multi-choice question for the following article: Article: The world's biggest Internet search engine, Google, has proven once again to be King of the Web. Users can download "Google Wi-Fi" software and then enjoy free Wi-Fi service available in some US cities since last Tuesday. Wi-Fi is short for "Wireless Fidelity" . It allows laptop computers and personal digital assistants to the Internet at high speed by radio signal. A person with a Wi-Fi enabled computer can connect to the Internet when near one of the network's access points. The place covered by one or several access points is called a hotspot. Google has already set up two "hotspots" in the US city of San Francisco which provide a free Wi-Fi service. The Wi-Fi technology even allows users to enjoy a free Internet phone service. Some scientists argue that Wi-Fi may replace mobile phone networks. Wi-Fi is still limited to a few cities, where there are "hotspots". But its capability of sending information has already done better than that of the mobile phone network, even that of 3G(Third Generation Telecommunication Technology). Some scientists have started to call Wi-Fi 4G. In addition to a high speed Internet connection, Wi-Fi has other advantages compared to mobile phones. Wi-Fi is global. The same Wi-Fi system works in different countries around the world. Different from using cell phones, you don't need to change computers to use Internet phones when you go to other places and most importantly, many Internet phones cost you nothing at all.
A: Question: Which of the following is NOT true of Wi-Fi?Options:A The high speed Internet connection.B Many free Internet phones.C Being used in all the US cities.D Using the same computers for Internet phones when you go to other places.Answer:C

[Q]: Write a multi-choice question for the following article: Article: The ecosystem is 1ike a chain.If any of the links are broken,the whole system is in danger.This is why wetland protection has been put high on the agenda in recent years.Zhao,vice--director of the State Forestry Administration,says nearly 60 percent of the country's natural wetlands are still not under effective protection.Most Chinese people are ignorant about the importance of protecting the wetlands. Ocean,forestry and wetlands are the three global ecological systems.Wetlands can conserve and purify water resources, prevent flooding and help protect the ecosystem. As well as ecological values, they can also offer economical returns. In recent years,many wetlands have become farmland.Drawing too much underground water,hunting and fishing also ruin their ecological system. Every year,the wetlands in the Sanjiang Plain of Northeast China provide habitat for birds.Local residents search the area for the birds' eggs. They consider the eggs to be a natural gift. rather than wildlife that should be protected. If they were educated,perhaps this is one activity that could be brought to an end. China is now ready to make a plan to save some of these areas.Some have been restored to raise awareness among the public.But these moves are not enough.There should be laws in place to provide legal support to the fight. Environment protection is a campaign which needs support from everyone in society.Education may be the first step.

Question: Write a multi-choice question for the following article: Article: Some good news for online holiday shoppers: bargain-hunting binges will drive prices down as web-based retailers compete to offer bigger discounts, marketing researchers predict. A recent survey by Shopzilla found that nearly 84 percent of online retailers would offer Cyber Monday discounts, up 12 percent from last year. Cyber Monday, the first Monday after Thanksgiving, is the online response to Black Friday, the day after Thanksgiving when stores are traditionally flooded with customers, some of whom camp at the entrances overnight to take advantage of discounts. However, in the current economic climate, online retailers have felt pressure to offer sales and discounts even before Black Friday. But how online retailers decide to offer those big savings isn't a simple matter of trying to attract the consumers who are watching their wallets, Bohlmann of Sabanci University in Istanbul says. Online stores will also pay attention to the deals their competitors are offering, potentially leading to price wars between certain retailers to attract all those potential bargain-hunting customers. Online shoppers can be divided into two types, Bohlmann said, --switchers and --loyals. Switchers compare prices between retailers and go for the cheapest one, while loyals stick to one brand or store. It almost doesn't matter what price you charge. Online retailers will look at the percentage of switchers and loyals they have in order to decide whether to offer discounts. The more switchers they have, the more likely they will offer discounts. But retailers don't just look at the percentage of their own customers; they also look at the competition. If one online store has a higher percentage of loyals than the competitor, it can afford to keep prices higher. On the contrary, if it has a higher percentage of switchers than the competitor, it might want to lower prices.
