input: Please answer the following: Write a multi-choice question for the following article: Article: As a young girl, Margaret "Mattie" Knight never played with dolls, preferring to make toys for her brothers instead. In 1849, Knight went to work in a cotton factory where she witnessed a "shuttle," a device that carries thread back and forth across a textile loom , fly off the machine when the thread broke, striking and killing a young boy about her own age. The 12-year-old Knight developed a safety mechanism that made it impossible for a shuttle to leave the loom. The design was so effective, soon virtually every new power loom carried her invention, saving countless workers from injury or death. Being so young, she didn't bother to patent the device, so she never received payment. Knight wouldn't make the same mistake later in life when she invented a machine that could produce flat-bottomed paper bags. Knight had built a small wooden model in her home, but she needed a metal version to show it could hold up to the stress of mass production. So she hired Charles Annan to make the full-sized machine for her, only to have him try to claim the patent for himself. When Knight sued , Annan's argument was that the design had to be his, because no woman could possibly understand the complex mechanics. Knight proved him wrong when she brought back her wooden prototype and explained how every part worked. She won the case in 1871, making her the second woman to hold an American patent. Over a hundred years later, her design is still used as the basis for many modern flat-bottom bag machines. But that wasn't the last the world heard of Mattie Knight. During her lifetime, she made about 90 inventions and received 26 patents, becoming one of the most productive female inventors of the 19th century.

Please answer this: Write a multi-choice question for the following article: Article: Global emissions of carbon dioxide from fossil fuel burning jumped by the largest amount on record in 2010. Emissions rose 5.9 percent in 2010, according to an analysis released on Sunday by the Global Carbon Project. Scientists said the increase was almost certainly the largest absolute jump in any year since the Industrial Revolution. The increase solidified a trend of ever-rising emissions that will make it difficult, if not impossible, to stop severe climate change in coming decades. The burning of coal represented more than half of the growth in emissions, the analysis found. In the United States, emissions dropped by a remarkable 7 percent in the year of 2009, but rose by over 4 percent in 2010, the new analysis shows. "Each year, emissions go up, and there's another year of negotiations, another year of indecision," said Glen P. Peters, a researcher at the Center for International Climate and Environmental Research. "There's no evidence that this path we've been following in the last 10 years is going to change." Scientists say the rapid growth of emissions is warming the Earth and putting human welfare at long-term risk. But their increasingly urgent pleas that society find a way to limit emissions have met sharp political resistance in many countries because doing so would involve higher energy costs. The new figures show a continuation of a trend in which developing countries have surpassed the wealthy countries in their overall greenhouse emissions. In 2010, the burning of fossil fuels and the production of cement sent more than nine billion tons of carbon into the atmosphere, the new analysis found, with 57 percent of that coming from developing countries. On the surface, the figures of recent years suggest that wealthy countries have made headway in stabilizing their emissions. But Dr. Peters pointed out that, in a sense, the rich countries have simply exported some of them. The fast rise in developing countries has been caused to a large extent by the growth of energy-intensive manufacturing...

Problem: Write a multi-choice question for the following article: Article: The Student symphonic orchestra of Fairfax,Virginia recently celebrated its first anniversary.A young man named Matthew Martz(Matt) started the group in his last year of high school with twelve friends from the school orchestra.Michelle Bui was one of them. She said."Matt is one of my very good friends,so I did it as a friend,but also because I love playing the violin." Michelle,who is now in college.says she likes the idea that the students run the orchestra themselves. Orchestra member Lizzie Culbertson plays the French horn.She said,"It has a versatile sound,first of all.I can do so just strings . We don't have a complete orchestra or anything." Thirteen-year-old oboe player Kanika Sahi is the youngest member. He said, "They just show me how to be better. I am learning different techniques of playing." Matt Martz leads the orchestra as the conductor. Matt is now in college, studying music education. The orchestra's rehearsals bring him back to his hometown every weekend. The orchestra gives him the chance to improve his teaching skills. The orchestra performs for free but receives donations that help pay for necessities like sheet music.Matt Martz said."In our first concert.we made l,100 dollars,which helped pay for a lot of music that we had bought."Then this last concert in January,we made over l,500 dollars which is just incredible.

A: Question: What does Matt Martz think of the January concert?Options:A He is very satisfied.B He is disappointed.C He is a little regretfulD He is very sorry.Answer:A

input question: Write a multi-choice question for the following article: Article: Like distance runners on a measured course,all of us will move through time in a roughly predictable pattern. In the first stage of our lives,we develop and grow, reaching toward the top of physical vitality . After we grow up,however, the body begins a process of gradually wearing out. A new awareness of physical fitness may help lengthen our years of health and vitality,yet nothing we do will work to stop the unavoidable force of aging. Most of the changes of aging take place deep inside the body.The lungs become less able to take in oxygen.Powerful muscles gradually lose their strength.The heart loses power and pumps less blood.Bones grow easier to break. Finally, we meet a stress,a stress that is greater than our physical resistance.Often,it is only a minor accident or chance infection(a disease caused by virus),but this time, _ brings life to an end. In 1932,a classic experiment nearly doubled the lifetime of rats,simply by cutting back the calories in their diet The reason for the effect was then unknown. Today, at the University of California at Berkley, Dr.Paul Seagle has also greatly lengthened the normal lifetime of rats.The result was achieved through a special protein limited diet,which had a great effect on the chemistry of the brain.Seagle showed that within the brain,specific chemicals control many of the signals that influence aging.By changing that chemical balance,the clock of aging can be reset. For the first time, the mystery of why we age is being seriously challenged.Scientists in many fields are now making striking and far-reaching discoveries. An average lifetime lasts 75 years,yet in each of us lies a potential for a longer life.If we could keep the vitality and resistance to disease that we have at age twenty, we would live for 800 years.???
