Problem: Given the question: Write a multi-choice question for the following article, with the given choices and answer: Article: Quick and Quack were two brave little ducks who lived with their mother. Both were really fast and were always competing against each other. One day, after visiting their uncle Ducklass, Quack shouted, "Last one home is a goose!" and both ducks swam quickly down the river. They both knew the way well, but Quack had been preparing a trick for some time. He had realized that the current in the middle of the river was stronger, and would help him. So, even though Mother Duck had told them never to swim in the middle of the river, Quack paddled over to it. "I'm old enough now to swim here," he thought to himself. It wasn't long before he realized his mother had been right. He was going much faster than Quick, and was developing a big lead. Quick was not amused. He never disobeyed his mother, and now he was going to lose the race! As they went on, the current got stronger. Quack proudly crossed the finishing line, without realizing he headed straight for a big whirlpool in the middle of the river. Before he could react, he was turning around in it, unable to escape. No duck was strong enough to swim in those waters, and poor Quack kept swallowing water. The fact that he was struggling hard didn't help matters much either. Fortunately, a cow from a nearby farm came by, and seeing Quack, he jumped in and rescued him. When he was on dry ground, he remained uncomfortable for quite some time. That provided quite a laugh for different animals that had been watching. Options: A he was afraid to swim in deep water B he didn't know the way there very well C his mother had told him not to do so D he was afraid of being trapped in the whirlpool Answer: C his mother had told him not to do so Question:

input question: Write a multi-choice question for the following article, with the given choices and answer: Article: Mosquitoes have an extraordinary ability to target humans far away and fly straight to their unprotected skin. Regrettably,mosquitoes can do more than cause an itchy wound. Some mosquitoes spread several serious diseases,including Dengue,yellow fever and malaria. Over one million people worldwide die from these diseases each year. New research now shows how mosquitoes choose who to bite. Mosquitoes need blood to survive. They are attracted to human skin and breath. They smell the carbon dioxide gas,which all mammals breathe out. This gas is the main way for mosquitoes to know that a warm-blooded creature is nearby. But mosquitoes also use their eyes and sense of touch. Michael Dickinson is a professor at the California Institute of Technology. His research shows how these small insects,with even smaller brains,use three senses to find a blood meal. Michael Dickinson's team used plumes--a material that rises into the air of carbon dioxide gas into a wind tunnel. They then used cameras to record the mosquitoes. The insects followed the plume. Then,the scientists placed dark objects on the lighter colored floor and walls of the tunnel. Mr. Dickinson said,at first,the mosquitoes showed no interest in the objects at all. "What was quite striking and quite surprising is that the mosquitoes fly back and forth for hours. These are hungry females and they completely ignore the objects on the floor and wall of the tunnel. But the moment they get a hit of CO2,they change their behavior quite obviously and now would become attracted to these little visual blobs ." This suggested to the researchers that a mosquito's sense of smell is more important in the search for food. Once mosquitoes catch a smell of a human or animal,they also follow visual signals. Options: A Sense of smell. B Sense of touch. C Sense of sight. D Smart brains. Answer: A Sense of smell. Question:???
output answer: What do mosquitoes mainly use to find their targets?

Please answer this: Write a multi-choice question for the following article, with the given choices and answer: Article: Leon, 12, was born without fingers on his left hand.That didn't -stop him from being able to do many tasks. But Leon could not grasp more than one object at a time. So Leon's father, Paul, created a prosthesis ,using a 3D printer. Now Leon has fingers that open and close."It was a do-it-yourself, father and son adventure," says raw. When Leon was a baby, his doctor advised his parents not to give him a prosthetic hand until he was in his early teens. "The doctor said Leon should first learn to get full use out of the hand he was born with," says Paul. As Leon got older, his father looked into buying a prosthetic hand, which can cost as much as $30,000. Paul found a more affordable solution. One day, Paul discovered a video on the Internet about Robohand, a prosthesis created with a 3Dprinter. He downloaded the free instructions and called Robohand's creators for advice. They told him all he needed was a 3D printerwhich costs around $2,000- and some materials. Luckily, Leon's school had recently purchased a 3D printer and it offered to help Paul build the hand for Leon."We used a soccer shin guard ,cardboard, and tape. They cost about$10," says Paul. With his new hand, Leon can do things better. "I can help my mom more, because now I can carry two grocery bags,"he says. Leon's father has already built .several hands for Leon. Leon helps design each one. He says there's one thing in particular that he wants to do with a future prosthesis."The goal," he tells the reporter from the local evening paper,"is to be able to tie my shoelaces:' Options: A An advertisement B A newspaper C A poster D A travel guide Answer: B A newspaper Question:
