Q: Write a multi-choice question for the following article: Article: Most of the flowers in nature are red, orange and yellow. If we have seen a black flower, it's a chance in million. People have made a census ( ) to colors of more than four thousand kinds of flowers and discovered that only eight of them are black. As we know, sunlight is formed by seven different colored lights. The wave length of each light is different, so the quantity of heat in each light is also different. Flowers, especially their petals ( ) , are easy to be harmed by high temperature. Black flowers can take in all the light waves which cause the flowers to dry up in a high temperature. So black flowers can rarely survive sunlight. But red flowers, orange flowers and yellow flowers can protect themselves from sunlight by reflecting the red light, orange light and yellow light, each of which has a large quantity of heat.
A: Question: Which of the following ideas is NOT true?Options:A People have found that only a few kinds of flowers are black.B Flowers are easy to be harmed by very high temperature.C Red, orange and yellow flowers can also absorb the light of all wave lengths.D The black flowers cannot protect themselves from sunlight.Answer:C

Q: Write a multi-choice question for the following article: Article: A ground-based system that uses much stronger signals than GPS can find your location in cities and indoors. It is a new positioning system that could compete with GPS to make sure you never lose your directions again. Instead of satellites, Locata uses ground-based equipment to send a radio signal over a localized area that is a million times stronger on arrival than GPS. It can work indoors as well as outdoors, and the makers claim that the receivers can be shrunk to fit inside a regular cell phone. Even the US armies, which invented GPS technology, signed a file last month agreeing to a test of Locata at the White Sands Missile Range in New Mexico. "This is one of the most important technology developments for the future of the positioning industry," says Nunzio Gambale, CEO and co-founder of the firm Locata, based in Griffith, Australia. As for the Locata's correctness, Christopher Morin of the US Air Force tested it recently at White Sands, and it worked to within 18cm along any axis . Morin said it should be possible to get the _ down to 5cm. The tests were performed in an open desert where GPS also worked beautifully, but its signal was weak--like a car headlight from 20,000 kilometers away--and easily cut off by solid objects . Locata's signal was far stronger, though not guaranteed to work in a complex urban environment, said David, speaker of the UK' s General Lighthouse Authorities. Locata's technology will face competition in the race to transform indoor navigation. But it could shine in specific areas, Gambale said. Robots with Locata could easily navigate inside buildings without the complex optical systems they need at the moment. And the process that handles correct location data could not only guide you around a mall, railway station or airport, but also take you to the exact shelf in a shop for the product you want. It would be small and cheap enough for smart phones and it should be available within five years--a similar path to the one GPS took on its way towards the world, he said.
A: Question: What can we know from the passage?Options:A Locata is as small as a cell phone.B GPS is the most practical position system at present.C Locata will tell you how to get what you want in the future.D Locata will enter our lives through the cell phone, just like GPS.Answer:D

Q: Write a multi-choice question for the following article: Article: How to be Prepared Electricity, water, gas and telephone may not be working after an earthquake. The police and fire department are likely to be tied up. You should be prepared to take care of yourself for at least three days, preferably for a week. This list can also be applied to other disasters, such as floods or wildfires. 1. food and water (a gallon a day per person) 2. a first aid kit 3. a fire extinguisher suitable for all types of fires 4. flashlights, a portable radio extra batteries 5. blankets, clothes, shoes and money (ATMs may not work) 6. baby and pet food It's also a good idea to decide beforehand how and where your family will reunite if separated during a quake and to conduct in-home practice drills. During an Earthquake If you are indoors, stay there. Get under and hold onto a desk or table, or stand against an interior wall. Stay away from exterior walls, glass, heavy furniture, and stay away from windows and outside walls and do not use the elevator. If you are outside, get into the open, stay into the open, stay away from buildings, power lines or anything else that could fall on you. If you are driving, move the car out of traffic and stop, avoid parking under or on bridges or overpasses, Try to get clear of trees, light posts, signs and power lines. If you are in a crowded public place, avoid panicking and do not rush for the exit. Stay low and cover your head and neck with your hands and arms. After an Earthquake If the phone is working, only use it in case of emergency. Likewise, avoid driving if possible to keep the streets clear for emergency vehicles. Be aware that items may fall out of cupboards or closets when the door is opened, and also that chimneys can be weakened and fall with touch. Check for cracks and damage to the roof and foundation of your home. Listen to the radio for important information and instructions. Remember that _ , sometimes large enough to cause damage in their own right, generally follow large quakes. If you leave home, leave a message telling friends and...

Q: Write a multi-choice question for the following article: Article: It is now February 7, 2035. The search engine TalkTalk will be open to the public next week and this service will soon be something beyond your imagination. For the first time you can not only talk to the search engine, but you can discuss with it what you are looking for. For example, if you want to know more about the oil price, TalkTalk asks if you want to know the current oil price, the development of the oil price, or news related to the oil price. You say that you want to read news about it and TalkTalk then directs you to your source, or lets you have the latest news related to the oil price in order from the most respectable sources. Compared with other search services that use a certain algorithm to provide data from a search, the artificial intelligence behind TalkTalk is said to easily spot if a certain source is aiming to cheat the searcher. TalkTalk also judges and stores every given reply and discussion, to learn how to give correct answers. TalkTalk is also set to answer questions directly where there is a definite answer. How well this will work in the long run is yet to be seen, but thousands of people have tested TalkTalk and the quality is really good. The first talking search engine saw the light of day more than 30 years ago and was called Speegle. It could read the results from a written search on the Internet, and was mostly for blind people. So far, TalkTalk cannot read the information from a certain source to you by phone, if it is not freely available. There are currently talks to find an arrangement for this, but it would most likely be difficult because of copyright . TalkTalk is available over the Internet and also by phone, even though it only speaks English. There are no plans to add other languages in the near future, most likely because it will cost a lot of money. When you are tired of asking TalkTalk all your questions, just ask, "Where is TalkTalk?" and you will get an answer that will make you leave it with a smile on your lips.
