input question: Write a multi-choice question for the following article: Article: A man steps on what seems like solid ground but discovers with horror that the ground is _ beneath his feet. The man struggles desperately, but he is trapped. He cannot escape. Slowly he sinks deeper and deeper until at last he is gone, buried in the treacherous earth. The solid ground was solid only in appearance. It was actually quicksand, which is a deep mass of fine sand mixed with water. How is quicksand formed? Water pushes up from below the surface and is held by the sand. The grains of sand are forced apart by the water. They cannot hold any weight. The subsurface water may have come from a spring, a river or a stream. Sometimes pools of water near beaches become filled with sand. When the soil under these pools does not allow for good drainage , the sand can become stretches of quicksand. Is it true that a man who steps into quicksand is doomed to die? No, for men have fought their way from quicksand to firm land again. It is panic that creates the condition that can result in death, for the more a person struggles, the worse matters become. Quick movements will make the sand give way temporarily , but then it rushes and settles solidly around the body. A man trapped in quicksand should either lie back, or not move at all, except to stretch out his arms. When the weight of the sand his body has displaced equals his weight, he will stop sinking. With feet held still, and with slow movements of the arms, as in the backstroke in swimming men can manage to roll to safety and reach firm ground.???
output answer: Question: Men can manage to reach firm ground by _ .Options:A holding feet still and moving arms slowlyB lying back calmly and moving arms frequentlyC stretching out arms and swimming quicklyD swimming quickly and moving arms slowlyAnswer:A

input question: Write a multi-choice question for the following article: Article: Bruce Alberts, the former President of the National Academies (USA), has now taken over as Editor-in Chief of Science. Judging by his editorial in this week's issueConsidering Science Education there could be some interesting times ahead inScience offices. Here's part of what Bruce has to say about science education... I consider science education to be critically important to both science and the world, and I shall frequently deal with this topic on this page. Let's start with a big-picture view. Science has greatly advanced our understanding of the natural world and has enabled the creation of countless medicines and useful devices. It has also led to behaviors that have improved lives. The public appreciates these practical benefits of science, and science and scientists are generally respected, even by those who are not familiar with how science works or what exactly it has discovered. But society may less appreciate the advantage of having everyone acquire the ways of thinking and behaving that are central to practice of successful science: scientific habits of mind. These habits include a critical attitude toward established claims and a strong desire for logic and evidence. As famous astronomer Carl Sagan put it, science is our best detector . Individuals and societies clearly need a means to logically test the constant clever attempts to operate our purchasing and political decisions. They also need to challenge what is unreasonable, including the intolerance that led to so many regional and global conflicts. So how does this relate of science education? Might it be possible to encourage, across the world, scientific habits of mind, so as to create more rational societies everywhere? In principle, a strong expansion of science education could provide the world with _ , but only if scientists, educators, and policy-makers redefine the goals of science education, beginning with college-level teaching. Rather than only conveying what science has discovered about the natural world,...???
output answer: Question: Which of the following is NOTincluded in the "scientific habits of mind"?Options:A A critical attitude toward established claims.B A strong desire for logic.C A clever and active mind.D A strong desire for evidence.Answer:C

input question: Write a multi-choice question for the following article: Article: It is common for older people to forget things. Now an American study has found that memory starts to fail when we are young adults. People younger than thirty years of age usually do not know that they are starting to forget information. But scientists from the University of Michigan say the loss of memory has usually already started. Researchers say people do not observe this slow reduction in mental ability until the loss affects their everyday activities. Denise Park led the new study. She directs the Centre for Aging and Cognition at the Institute for Social Research at the University of Michigan. Her team studied more than 350 men and women between the ages of twenty and ninety years. The study identified people in their middle twenties with memory problems. She says young adults do not know they are forgetting things because their brains have more information than they need. But she says that people in their twenties and thirties are losing memory at the same rate as people in their sixties and seventies. Ms. Park says people between the ages of sixty and seventy may note the decrease in their mental abilities. They begin to observe that they are having more trouble remembering and learning new information. The study found that older adults are more likely to remember false information as being true. For example, they remembered false medical claims as being true. Younger people remembered hearing the information. But they were more likely to remember that it was false. Ms. Park is now using modern imaging equipment to study what happens in the brains of people of different ages. She is studying what parts of the brain older adults use for different activities compared to younger adults. Ms. Park says mental performance is a direct result of brain activity and brain structure. She says keeping the brain active is important. She hopes future studies will identify ways to improve the operation of our aging minds.???
