[Q]: Article: This morning, a Virgin Atantin 747 Jumbo Jet became the first commercial airplane to fly on biofuel. The short flight from London to Amsterdam used a blend of 20% babassu oil mixed with 80% conventional jet fuel. What was really exciting about the flight was the fact that the engine did not have to be altered in any way for the biofuel to work While this is a great initial step in trying to reduce CO2(carbon-dioxide)emissions from airplanes. there are a lot of hurdles that still need to be overcome. First and foremost, unlike the normal fuel used to run airplanes (known as Jet A),biofuel freezes at high altitudes. Also, Jet'A'fuel burns consistently (at the same pace),which means it provides a safe and reliable fuel for long flights--engineers are not sure if biofuel will be able to do the same. The biggest hurdle to a full biofuel switch is our ability to be able to grow enough crops that can be converted to biofuel. There are two concerns that scientists have in this matter - the first is that the land to grow the extra crops will come from clearing more of our forests and the second is that since it competes with what we eat, the price of food will go up. However, Richard Branson of Virgin Airlines, envisions that if biofuel starts to replace oil on a greater basis, it will be manufactured from algae produced in sewage treatment plants, not from food sources. Birgin Airlines is not the only one trying to look for alternative fuel sources. Earlier this year, an Airbus A380 used another alternative fuel-a man-made mix of gas-to-liquid, in one of its four engines. The flight was tested by Rolls Royce (manufacturer of jet engines), in partnership with Shell (an oil company). Rolls Royce is also working with Air New Zealand on a similar project. While a complete switch to alternative fuel may take years, it is very encouraging to see airlines, oil companies and airplane manufacturers all coming together to try to make it happen!
Question: .Why does Virgin Airlines try to replace normal fuel with biofuel?
Options: (A) To cut down the flight cost of the company. (B) To remove some hurdles for the biofuel to work. (C) To reduce CO
2 emissions from airplanes. (D) To test plane engines on biofuel.

[Q]: Article: The First of May is a Bank Holiday--the first public holiday of the year in England. Most people consider it a special day ,the beginning of summer ,a day when the light lasts long into the evening ,and when we can look for warm weather .We don't always get it .We feel disappointed ,but not surprised if there are cold winds and frosts at night in May .Winter should be over .Most people know that in the past ,when farming occupied almost everyone ,the changing seasons were of great importance .In that older time there was every reason to celebrate May Day .Customs of those celebrations remain. Of these customs ,the best known is the choosing of a May Queen and the dancing round Maypole .Even these customs are little more than memories now--but in the last century it was quite common in villages and small towns ,and even in schools and colleges ,for a pretty and popular girl to be chosen Queen of the May .It was a great honour to be chosen .For a day she wore a light and flowery dress, carried garlands ,and was ceremonially crowned with flowers .She presided over a procession ,as a rule with a number of attendants ,and over the Maypole dancing and all kinds of entertainment .The Maypole was slender tree trunk ,cut off its branches, with beautiful ribbons fastened to the top .The dancing was designed in such a way that the dancer's movements move the ribbons into a pattern. This, as you can imagine ,required skill from the dancer ,and was not achieved without practice . It's the Celtic people who celebrated the First of May as a spring festival .Their celebration seems to have had little to do with taking pleasure in early ,beautiful flowers and in warmer weather! They called it Beltane--the fire of the god Bel .They lit fires ,in the expectation that their blaze would help the sun in its struggle to regain its strength. They drove their cattle between banks of flame in the expectation that the terrified beasts would be purified and protected from disease .A tree ,which must have been blackened with smoke ,stood in the middle of the fires ,and is thought to have been the origin of the Maypole .Their priests made sacrifices to the goods in the hope of good harvests and sufficient store of food for the winter. There was dancing certainly ,but it was noisy and cheerful ,since its purpose was not to weave a pattern of colored ribbons ,but to drive out evil spirits from the earth and to arouse those kind spirits.
