Read the following article and select the best answer. Article: An early invention by Albert Einstein has been rebuilt by scientists at Oxford University. They are trying to develop an environmentally friendly refrigerator that runs without electricity. We all know that modern fridges cause damage to the environment. They work by using a kind of man-made greenhouse gas called Freon , which is far more damaging than carbon dioxide. Now Malcolm McCulloch, an electrical engineer at Oxford, is leading a three-year project to develop appliances that can be used in places without electricity. His team has completed a prototype of a fridge patented in 1930 by Einstein. It used only pressurized gases to keep things cold. The design was partly used in the first refrigerators, but the technology was dropped when more efficient compressors became popular in the 1950s. That meant a switch to using Freon. Einstein's idea uses butane and water and takes advantage of the fact that liquids boil at lower temperatures, when the air pressure around them is lower. "If you go to the top of Mount Qomolangma, water boils at a much lower temperature than it does when you're at sea level and that's because the pressure is much lower up there," said McCulloch.At one side is the evaporator , a bottle that contains liquid butane. "If you introduce a new vapor above the butane, the liquid boiling temperature decreases and, as it boils off, it takes energy from the surroundings to do so," says McCulloch. "That's what makes it cold." The gas fridges based on Einstein's design were replaced by Freon-compressor fridges partly because Einstein's design was not very efficient. But McCulloch thinks that by changing the design and replacing the types of gases used it will be possible to quadruple the efficiency. However, McCulloch's fridge is still in its early stages. "It's very much a prototype," he said. "Give us another month and we'll have it working." Question: We can learn from the text that the prototype completed _ . - changed the air pressure around it - was tested on the top of Mount Everest - increased the liquid boiling temperature - used only pressurized gases to keep things cold
(A).
used only pressurized gases to keep things cold

Read the following article and select the best answer. Article: The Segway Human Transporter was invented by Dean Kamen.It is a two-wheeled vehicle designed for a single rider standing upright over its single axle and navigate using a set of handlebars resembling those on a bicycle.Electrically powered, it could travel over 15 miles on a single charge and reach speeds up to twelve miles per hour.Its speed and direction can be controlled by riders' changing their weights. A college dropout and self-taught engineer, Kamen already held over 100 patents for his inventions when he developed the one he hoped would revolutionize short-distance travel.While still in college, Kamen started developing the medical devices that made his name.Later, he changed focus to the challenges faced by wheelchair users.His robotic wheelchair known as IBOT could climb stairs.This robot ended up paving the way for the Segway. Before showing his most recent invention, Kamen had kept it a top secret for months.When it turned out to be little more than a motor scooter, many publicly expressed their disappointment.On closer examination, however, even his critics had to admit that the vehicle was an engineering achievement.It answered the prayers of anyone who is worn out when walking downtown.Not everyone welcomed the Segway's arrival, though.Some complained it was too expensive, while others said it would further weaken the average American ' s fitness.A Japanese inventor even accused Kamen of stealing the idea for the Segway from him. Despite the controversy, the U.S.postal service began using Kamen's invention a month after its appearance, and a factory was built with plans to produce about 40,000 Segways every month.The argument is still on whether the Segway will be remembered as the greatest invention since the light bulb, or just another forgettable electronic device.Anyway, trips to the local supermarket will never be the same again. Question: Which is not a feature of the Segway? - One person at a time can ride on it. - It has two wheels with a single axle. - It is powered by electricity and can go up to 12mph. - Riders increase the speed by moving the handlebars
(A).
Riders increase the speed by moving the handlebars

It takes place in the week before term starts, from 24th-28thSeptember, but you should plan to arrive in Bingham on the 22ndor 23rdSeptember. Why do we think it is important? We want you to have the best possible start to your studies and you need to find out about all the opportunities that college life offers. It will enable you to get to know the college, its facilities and services. You will also have a chance to meet staff and students. How much will it cost? * International students (non-European Union students) For those students who do not come from European Union (EU) countries, and who are not used to European culture and customs, the progamme is very important and you are strongly advised to attend. Because of this, the cost of the programme, without accommodation, is built into your tuition fees. * EU students EU students are welcome to take part in this programme without accommodation for PS195. Accommodation costs (international and EU students) The cost of accommodation for one week is PS165 If you have booked accommodation for the year ahead (41 weeks) through the college, you do not have to pay extra for accommodation. You can ask us to pre-book accommodation for you one week only in a hotel with other International students. What is included during the programme? Meals: lunch and an evening meal are provided as part of the programme. Please note that breakfast is not available. Information: including such topics as accommodation, health, religious matters, study skills, and other necessary information. Social activities: including a welcome party and a half day trip round Bingham. Question: Which of the following might NOT be included in the programme? - Learning how to study in the college - Looking for a part-time job in neighborhood. - Understanding some taboos in European society. - Travelling around Bingham.
(A).
Looking for a part-time job in neighborhood.
