In this task, you're given an article and an answer. Your task is to generate the question for the answer based on the given article.

Input: Consider Input: Article: Every child has written their names on the beach at some point. But whereas most people's "handwriting" is washed away, one super-rich Arab sheikh has ensure that his graffiti will last a little longer. Hamad Bin Hamdan Al Nahyan, 63, has scrawled his name in sand on an island he owns with letters so big that they be seen from space. The word "HAMAD" measures 1,000 meters high and is a staggering two miles long from the "H" to the "D" on the Al Futaisi Island. And rather than allow the writing to be washed away by the ocean, the letters actually form waterways that absorb the encroaching tide. The ruler's name is even visible on Google's map service. Hamad dreamed up the idea and had his workmen work hard for weeks to craft the enormous piece of sand graffiti. It is not known how much it cost to make. However, the sheikh boasts a personal fortune second to the Saudi king's. Hamad, also known as the "Rainbow Sheikh", is a member of the Abu Dhabi Ruling Family. He is understood to have some 200 cars including seven Mercedes 500 SELs painted in different colors of the rainbow which he stores in a giant pyramid. The Arab sheikh had a taste for doing things on a large scale. He built the world's largest truck--eight times the size of the Dodge Power Wagon, with four bedrooms inside the cabin. Hamad constructed a motor home in the shape of a giant globe which is exactly 1 millionth the size of the actual earth. Alongside his displays of wealth he has become a well-known philanthropist in medicine and supplied a complete Kinney stone operating theatre to a public hospital in Morocco where he continues to fund its stuff.
Answer: Hamad is a man who boasts his fortune is second to the Saudi king's

Output: Which of the following in NOT true according to the passage?

Input: Consider Input: Article: Fahad Azad, an engineer in India, invented a robot named DuctBot.The toy-car sized DuctBot measured 23 centimeters in length, 19 centimeters in width and 9 centimeters in height and weighs just two kilograms. The robot is designed to snake through dark, narrow air conditioning ducts and clean them.A pair of LEDs fitted on the robot light up the dirty scenery, so _ can be captured by a camera. In order to control it more easily, Mr. Azad chooses to fix DuctBot on wheels.The robot can clean off lots of dirt, as well as dead pigeons and insects.Keeping indoor air in good quality and monitoring carbon-dioxide levels in buildings with central air conditioning is a challenge.It is important in some places where clean air can mean a difference between life and death, such as hospitals.Dirty air has a bad influence on people's health. EPSCO, a Dubai-based company which specializes in improving indoor air quality, read about Mr. Azad's invention in a national newspaper after he had won an international robotics competition.EPSCO had cleaning equipment, but it needed someone to get into those ducts to do the dirty, dangerous work.Across India, for example, the task still falls to children.They are small enough to go through those ducts. In 2005, Mr. Azad who was still at university decided to do something about it.Six years later his own company, Robosoft Systems, has Bluestar, EPSCO and the Indian Navy, some leading air condition makers, as partners. Mr. Azad and his ten employees are currently exploring robot designs to examine oil tanks or sewage pipes.Their biggest challenge is to make the robots user-friendly enough.Mr. Azad hopes that the robot could eventually be operated not by engineers but by workers.There will be lots of difficulties they need to overcome in the future.
Answer: It is designed to move like a snake in the ducts.

Output: What can we learn about Ductbot?

Input: Consider Input: Article: Federal regulators Wednesday approved a plan to create a nationwide emergency alert system using text messages delivered to cell phones. Text messages have exploded in popularity in recent years, particularly among young people. The wireless industry's trade association, CTIA, estimates more than 48 billions text messages are sent each month. The plan comes from the Warning alert and Response Network Act, a 2006 federal law that requires improvement to the nation's emergency alter system. The act tasked the Federal Communications Commission (FCC) with coming up with new ways to alert the public about emergencies. "The ability to deliver accurate and timely warning and alert alters through cell phone and other mobile services is an important next step in our efforts to help ensure that the American public has the information they need to take action to protect themselves and their families before, and during, disasters and other emergencies," FCC Chairman Kevin Martin said following approval of the plan. Participation in the alert system by carriers -- telecommunication companies -- is voluntary, but it has received solid support from the wireless industry. The program would be optional for cell phone users. They also may not be charged for receiving alerts. There would be three types of messages, according to the rules. The first would be a national alter from the president, likely involving a terrorists attack or natural disaster. The second would involve "approaching threats," which could include natural disasters like hurricanes or storms or even university shootings. The third would be reserved for child abduction emergencies, or so-called Amber Alerts. The service could be in place by 2010.
Answer: To warn people of emergencies via message.
