The University of Illinois in the United States has a project called SAWBO--Scientific Animations Without Borders. It produces educational videos that can be downloaded to cell phones. The goal is to help people in developing countries improve their lives. One video shows farmers how to make a natural insecticide from neem seeds to prevent insect damage to crops. The process starts with sorting and drying the neem fruits. Then let the fruit dry in the sun for about three or four days, until they become brown. Using a mortar and stick, the fruits are slightly _ to remove the shells from the fruits without breaking the seed inside. The videos use computer animation . Some of the animated characters are a little funny looking-like a farmer with a long nose. But the subjects are serious, including a health video on preventing cholera . Team member Francisco Seufferheld says the information in the videos is meant to be quickly understood. He says, "The information is digested in such a way that in two minutes, we can transmit a complex idea." The researchers tested the seven-minute video on seven mobile phones. They wanted to see if people would share the video using Bluetooth wireless technology. With Bluetooth, files can be passed to a nearby phone even if neither phone is connected to the Internet. As a result, in one month, the video had spread to one hundred eighteen people in fifty different villages. "This is just incredible impact," said Francisco Seufferheld. The team has made a few videos so far. These are available in a total of eighty languages, dialects and accents. Professor Barry Pittendrigh says there are plans for more videos later this year. Question: What is the text mainly about? - A best-selling mobile phone - A valuable educational project for farmers - United States support for developing countries - A new type of scientist -farmer relationship

Read the following article and select the best answer. Article: On March 28th, the New York Times will begin charging all but the most infrequent users to read articles online. In a letter to readers, Arthur Sulzberger, Jr., the publisher of the paper, laid out the details of the paywall, which he said will go into effect immediately in Canada and on March 28th for the rest of the world. He called the move "an important step that we hope you will see as an investment in the Times, one that will strengthen our ability to provide high-quality journalism to readers around the world and on any platform." Sulzberger said that readers will be able to read 20 articles per month at no charge. Once they click on the 21st piece, however, they'll be presented with three payment options: $ 15 for four weeks of online and mobile application access, $ 20 for access to the site and the iPad application, or $ 35 for access to everything. People who already receive the printed paper through home delivery will enjoy free and unlimited access to the Times on all platforms. These details largely agree with earlier reports on how the paywall would work. The Times had made it clear that it did not want to imitate the total paywalls put into effect by papers such as The Times of London and Newsday, which block access to all contents unless the reader pays. The paper also signaled that it wants to stay relevant in the social media world. According to Sulzberger's announcement, people who come to the Times site from Facebook, Twitter or from blogs will be able to read those articles even if they have gone over their monthly limit. However, Sulzberger said that a limit will be placed on "some search engines", meaning that after readers have accessed a certain number of articles from search engines, any further articles they access from there will be added to their monthly count. It was reported that the only search engine that will be affected this way is Google, where there will be a five-article limit. This marks a clear attempt by the Times to close what could be a giant loophole , since so... Question: Why will the Times charge their online readers? - It wants to stay relevant in the social media world. - It has too many readers coming from the other sites. - It is seeking new financial sources for its development. - It is trying a way to offer better service to its readers.
It is seeking new financial sources for its development.

This is mainly due to greater international investment driven by the availability and lower cost of labor and manufacturing skills," explained Mr. Slagin Parakatil, Senior Researcher at Mercer. Mercer bases its annual survey on 39 quality-of-life factors, from political stability to schools, bars, restaurants and the environment. The top...
