Q: Write a multi-choice question for the following article: Article: Farmers can produce more by planting several different crops in the same field.But their success depends on which crops they plant together and how they mix   them in the filed.In the past, the only way the farmers could learn which crops grow best together is to plant them and wait for the results.Now, however, a computer can give them answers.A new computer program written by Dr John Vanderwell of Michigan University can tell a farmer which plants grow well together and which do not.It can tell him how to plant the different crops; if he should plant each in a separate row, or mix the crops in the same row.It can tell the farmer how changes in planting each of the crops will affect the production of all of them.And it can tell him which plants can help reduce losses   from diseases.
A: Question: Which of the following is NOT true?Options:A Computers can tell farmers how many plants can grow together.B With the help of computers farmers don't have to do a lot of work.C With the help of computers farmers can get better results.D The change of one plant may cause a change in production.Answer:B

Q: Write a multi-choice question for the following article: Article: Though "nanometer" is now a fashionable term all over the world,few people know exactly what it is.It has become a new favorite of manufacturers and sellers in recent years.Many "high-tech" products bearing the name "nano" have entered the market,bringing more mysterious feeling to surprised consumers. Nanometer is a very small length unit of measure,and is very small.One millimeter is 1000 micrometers,and one micrometer is 1000 nanometers.That is,one nanometer is one billionth of a meter.Nano materials are solid materials composed of particles or crystallites of less than 100 nanometer in size.Then,is a cup made of nano material really any different from an ordinary cup in function as far as how it works? Are nano cups really so wonderful?A reporter went to the Institute of Nanomedicine,which is the first such institute of such a sort in the world and the only one in China,specializing in researching the investigation  of the application of nano technology into medicine. Ji(director Institute of Nanomedicine): A water molecule is composed of 2 hydrogen atoms and 1 oxygen atom.It can be alterchanged only by special manipulation of the atoms.The material constituting the cup can have a nanometer particles size of the nano level.But it cannot change the chemical and physical properties of the water contained in it.The water in the cup is still water.When people drink it,it will produce no special effect on human body. Prof.Ji told the reporter,so far,the investigation of nano materials is still confined in the laboratory.No commercial micro products can be produced yet.With the present level of science and technology,the time of everyday goods age of daily use articles made of nanometer materials is still years away. The commodities labeled with nano marks in the market now are only traditional products coated with a thin layer of nanometer material,which makes them _ . Prof.Ji explained that nano cup is a real cup.It can also be included in the list of nano products in a certain sense.But the nano cup has not...

Q: Write a multi-choice question for the following article: Article: Bullied  kids face a high risk of mental health problems as teens and as young adults. Indeed, kids troubled by bullying may be worse off than those who had suffered physical abuse  or neglect, as the study found. Until recently, most studies of child victims focused not on bullying but on maltreatment , Dieter Wolke says. Maltreatment includes physical or emotional abuse, neglect or other behaviors that can harm a child. Wolke's team wanted to better understand bullying's long-term effects compared to those due to maltreatment. They focused on 4,026 children in the United Kingdom and 1,420 more in the United States. Information about bullying and maltreatment was collected for American children to age 13. They collected the same information for British youth up to age 16. The researchers also gathered data on each individiial's mental health as a young adult. Among the Americans, 36 percent of bullied kids had mental problems later. Those problems included anxiety, which is a state of excessive worry. They also included depression. That is a feeling of hopelessness that can last a long time. Among kids who had been maltreated by adults, 17 percent later suffered mental health problems. That was less than half the rate seen in people who had been bullied as school kids. In the U.K. group, the difference was less dramatic. Roughly 25 percent of the bullied kids reported mental health problems later, compared with about 17 percent who had been maltreated. But however you look at it, the findings are disturbing. And that's why Wolke says schools,health services and other agencies must work together to end bullying. Studies like this are important, says C.orinna Jenkins Tucker. They bring attention to the lasting impacts of bullying. Tucker does, however, question the value of comparing bullying to other types of abuse. Such an approach can make it seem like one type of bad experience is worse than the other, she says. In fact, both types have short-term and long-term effects on health. She'd like to see...
