Please answer this: Write a multi-choice question for the following article: Article: Have you dreamed of building your own machine? Do you wish you could invent something new? Here we look at a few British inventions of recent times. Adaptable glasses Do you wear glasses? If so, can you imagine life without them? In 1985, Joshua Silver, a professor at Oxford University, asked himself, "Can I invent a pair of glasses that could be changed by the wearer?" He designed two plastic lenses that are filled with a special liquid. Using syringes you change the liquid between the lenses until you can see clearly. The glasses are not beautiful but they are easy to use and cheap to make. The wind-up radio When you switch your TV on tonight, think about all those people without electricity. Thinking about this, Trevor Baylis came up with the idea of designing a radio that could be powered by hand. In common with Joshua Silver he wanted his invention to be cheap and easy to use. He wanted even the poorest people in developing countries, who don't have electricity and cannot afford batteries, to use it. The radio has a generator which is powered by turning a handle. In 1996 it won a BBC Design Award for Best Protect and Best Design. The Dyson cleaner In many homes around the world you can see a cleaner that looks like a spaceship. This is the Dyson vacuum cleaner which uses something called "cyclonic separation" to separate the dirt. You do not need a bag for your cleaner and it does not get blocked so it is very practical. The idea came to Sir James Dyson after he kept having problems with his vacuum cleaner. He decided he could design a better one and in 1993 he opened his own factory. The Dyson is now one of the best-selling cleaners in the UK and Dyson is believed to have earned over a billion pounds. The Zapata fly-board Ever dreamed of zooming through the water and leaping in the air like a dolphin? Now you can thanks to a fly-board, built by water sports enthusiast Frank Zapata. With it you can dive back in the water and out again. It's possible to jump to incredible heights out of the water --...

Please answer this: Write a multi-choice question for the following article: Article: Britain's seed bank, the only one in the world aiming to collect all of the planet's wild plant species, has reached its goal of banking 10 percent by 2010. The Millennium Seed Bank Project, run by Kew Gardens--one of the oldest botanical gardens--will officially place the 24,200th species on Thursday, a pink, wild banana from China. More than 50 countries are now on board with Kew's giant task but vast places of the globe, including India and Brazil, still need to join in and donate seeds, director Paul Smith said. The seed bank is one of the largest and most diverse in the world with more than 1.5 billion seeds. Its goal is to help protect the planet's bio-diversity during a time of climate change. The wild banana seed is under threat of extinction in southwest China from agricultural development. It is a vital food source for Asian elephants and important for growing bananas for human eating. Stored at minus-20 degrees centigrade, so they can last for thousands of years, the seeds await the day that scientists hope never comes--when the species no longer exist in the wild. It is a race against time, Smith said, because in the last ten years alone, 20 plants held in the bank have already been wiped out in the wild. He estimates that between a third and a quarter will become extinct this century. "It is pressing and it is happening now. An area, the size of England, is cleared of primary vegetation every year." Smith said. Because most of the world's food and medicines come from nature, protecting wild plant species is quite important, scientists say. There are already many other seed banks safeguarding food crops, which only account for 0.6 percent of plant diversity. For Kew's next goal--to collect a quarter of wild varieties by 2020--the botanists need 10 million pounds a year, or a further 100 million pounds on top of the 40 million they have already been granted.

Please answer this: Write a multi-choice question for the following article: Article: When the Farnsworth family moved to their new farm in 1919, eleven-year-old Philo was surprised to find it wired for electricity. This unusual circumstance contributed to his fate -- to become an important inventor of the twentieth century. By thirteen, Farnsworth had become a self-taught electrical engineer. He was able to fix the farm's generator when none of the adults could. In 1922, he read an article about a new idea of John Baird, a Scottish scientist, who had been working with the cathode ray tube for the transmission of electronic pictures and wanted to attempt it himself. Farnsworth studied everything he could find on the subject. Although many older engineers with money backers were already developing television, Farnsworth made a bold decision -- he was going to perfect a working model of it before anybody else. In college, Farnsworth continued his research with cathode ray and vacuum tubes, but the death of his father, the only money maker in the family, forced him to give up this research and find a job. His first job was for George Everson, with whom Farnsworth discussed his dream of television. While acknowledging the achievements of those who came before, Farnsworth thought that he could get closer. Everson agreed to risk $6,000 for the research. Backers came in 1927 to see the first American television, one year after Baird's. They were astonished to see the image of a single white line resolve itself on the screen before them, and agreed that this new invention was worth putting money into. In 1930, Farnsworth won a patent for his all-electronic TV. By the time he died, he had earned over 300 American and foreign patents for electronic and mechanical devices.
