input: Please answer the following: Write a multi-choice question for the following article, with the given choices and answer: Article: We all enjoy the beautiful show of color1s as leaves change each autumn. But did you ever wonder how and why this happens? To answer the question, first you have to understand what leaves are and what they do. Leaves are nature's food factories. Plants take water from the ground through their roots. And they take a gas called carbon dioxide from the air. Plants use sunlight to turn water and carbon dioxide into glucose . Glucose is a kind of sugar. Plants use glucose as food for energy and as a building block for growing. The way plants turn water and carbon dioxide into sugar is called photosynthesis . That means, "putting together with light". A chemical called chlorophyll helps photosynthesis. Chlorophyll is what gives plants their green color1. As summer ends and autumn comes, the days get shorter and shorter. This is how trees "know" to begin getting ready for winter. During winter, there is not enough light or water for photosynthesis. Trees rest during this time and live off the food they stored during the summer. They begin to shut down their food-making factories. The green chlorophyll disappears from the leaves. As the bright green fades away, we begin to see yellow and orange leaves. Small amounts of these color1s have been in the leaves all along. We just can't see them in the summer, because they are covered up by the green chlorophyll. The bright reds and yellows we see in leaves are made mostly in autumn. In some trees, like maples, glucose is caught in the leaves after photosynthesis stops. Sunlight and the cool nights of autumn turn this glucose into a red color1. The brown color1 of trees like oaks is made from waste left in the leaves. It is the mixture of all these things that makes the beautiful color1s we enjoy during autumn. Options: A can produce glucose, which can provide energy for trees' growth B can happen whenever there is light and water C is the process of putting sunlight together with chlorophyll D doesn't stop during the trees' lifetime even in winter Answer: A can produce glucose, which can provide energy for trees' growth Question:

Please answer this: Write a multi-choice question for the following article, with the given choices and answer: Article: London, Reuters--What could annoy teenagers enough to make them stop hanging out with friends and go home? No, it's not a visit from their mothers, and not a threat to take away their cellphones or pocket money. It's high-frequency noise. The UK police recently agreed to use a device called the Sonic Teenager Deterrent. It sends out a sound that makes teenagers become so impatient and angry that they have to cover their ears tightly and walk away. The sound is at extreme high-pitch that can be heard by those under 20. The body's natural ability to detect some wave bands decreases almost entirely after 20, so few adults can hear the sounds. The black-box device, nicknamed the Mosquito because of its sound, can be fixed to the outside walls of shops, offices and homes. It sounds to youngsters like a crazy insect or a badly played violin. But it causes no physical damage. A number of police forces and councils have given permission to use the system and want to install it at trouble spots. Staffordshire Police Inspector Amanda Davies, who has given the device to shopkeepers in the Moorlands area, said," It is controlled by the shopkeepers--if they can see through their window that there is a problem, they turn the device on for a while until the group has run away." Options: A young people often suffer from pains in ears B shopkeepers are troubled by noisy insects C high-frequency noise is beyond the listening ability of people over 20 D the police invented a new device to deal with teenagers Answer: C high-frequency noise is beyond the listening ability of people over 20 Question:

Problem: Write a multi-choice question for the following article, with the given choices and 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. Options: A Nothing but an electrical device. B A disappointing engineering mistake. C An expensive and disappointing invention. D Disappointing, but still a successful device. Answer: D Disappointing, but still a successful device. Question:

A: Which statement best describes the critics' reaction to the Segway?

input question: Write a multi-choice question for the following article, with the given choices and answer: Article: The passport photographs of the future could turn out to be more than just another pretty picture if a new computer technique developed by Israeli scientists catches on. Researchers at Ben-Gurion University, in Israel, have invented a way to hide information such as a fingerprint or signature in color images. They believe this could improve passport safety or be used to produce product bar codes or designs that cannot be seen. "The papers can be faxed, scanned and reprinted without hidden data disappearing," New Scientist magazine said last week. Joseph Rosen and a team of scientists worked out the new instrument by creating a mathematical model. The model turns a fingerprint or signature into a series of numbers which are used to shape the dots that make up a color picture. "Each dot can be forced out of the usual place slightly without noticeably changing the final appearance of the image," the magazine said. Several images that can be hidden in a single picture are scanned into a computer which does the work. The hidden images or fingerprints cannot be shown until the picture is scanned again. The computer rebuilds the fingerprint by measuring the displacement of the dots in the picture. The magazine said that if he model is used for passport checkpoints the picture can be unscrambled to show the fingerprint or signature and checked against the person holding the passport. The researchers are now working on a handheld, and instrument which could make unscrambling the hidden information easier. Options: A one's picture B one's fingerprint C one's signature D one's blood type Answer: D one's blood type Question:???
output answer:
The new passport photos will probably contain all EXCEPT _ .
