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.

Article: Dear Malia and Sasha, I know that you've both had a lot of fun these last two years on the campaign trail, going to picnics and parades and state fairs, eating all sorts of junk food your mother and I probably shouldn't have let you have. But I also know that it hasn't always been easy for you and Mom, and that as excited as you both are about that new puppy, it doesn't make up for all the time we've been apart. I know how much I've missed these past two years, and today I want to tell you a little more about why I decided to take our family on this _  When I was a young man, I thought life was all about me--about how I'd make my way in the world, become successful, and get the things I want. But then the two of you came into my world with all your curiosity and mischief and those smiles that never fail to fill my heart and light up my day. And suddenly, all my big plans for myself didn't seem so important anymore. I soon found that the greatest joy in my life was the joy I saw in yours. And I realized that my own life wouldn't count for much unless I was able to ensure that you had every opportunity for happiness and fulfillment in yours. In the end, girls, that's why I ran for President: because of what I want for you and for every child in this nation. I want all our children to go to schools worthy of their potential--schools that challenge them, inspire them, and instill in them a sense of wonder about the world around them. I want them to have the chance to go to college--even if their parents aren't rich. And I want them to get good jobs: jobs that pay well and give them benefits like health care, jobs that let them spend time with their own kids and retire with dignity. I want us to push the boundaries of discovery so that you'll live to see new technologies and inventions that improve our lives and make our planet cleaner and safer. And I want us to push our own human boundaries to reach beyond the divides of race and region, gender and religion that keep us from seeing the best in each... Question: According to the letter, which of the following is NOT true? Options: A: The writer and his two daughters had been apart for a long time. B: The writer hoped that his daughters would live up to his great expectations. C: The only way to settle the differences in the world is through violence. D: There still exist some divides of race and region, gender and religion somewhere in the world.

Read the article and select the best answer. Article: As is known to all, the organization and management of wages and salaries are very complex. Generally speaking, the Accounts Department is responsible for calculations of pay, while the Personnel Department is interested in discussions with the employees about pay. If a firm wants to adopt a new wage and salary structure, it is essential that the firm should decide on a method of job evaluation and ways of measuring the performance of its employees. In order to be successful, that new pay structure will need agreement between Trade Unions and employers. In job evaluation, all of the requirements of each job are defined in a detailed job description. Each of those requirements is given a value, usually in "points", which are added together to give a total value for the job. For middle and higher management, a special method is used to evaluate managers on their knowledge of the job, their responsibility, and their ability to solve problems. Because of the difficulty in measuring management work, however, job grades for managers are often decided without reference to an evaluation system based on points. In attempting to design a pay system, the Personnel Department should compare the value of each job with those in the job market. It should also consider economic factors such as the cost of living and the labor supply. It is necessary that payment for a job should vary with any differences in the way that the job is performed. Where it is simple to measure the work done, as in the work done with the hands, monetary encouragement schemes are often chosen, for indirect workers, where measurement is difficult, methods of additional payments are employed. Question: The main purpose of this passage is to     _    . Options: A: give details about the responsibilities of both the Accounts Department and the Personnel Department B: tell readers how a firm can succeed in adopting a new pay system C: explain how the performance of a job can be measured in points D: convince readers that management work is more difficult to evaluate than the work done by workers.
