user: Problem: Write a multi-choice question for the following article, with the given choices and answer: Article: Can people change their skin colour without suffering like pop king Michael Jackson? Perhaps yes. Scientists have found the gene that determines skin colour. The gene comes in two versions, one of which is found in 99 per cent of Europeans. The other is found in 93 to 100 per cent of Africans, researchers at Pennsylvania State University report in the latest issue of Science. Scientists have changed the colour of a dark-striped zebra fish to uniform gold by inserting a version of the pigment   gene into a young fish. As with humans, zebra fish skin colour is determined by pigment cells, which contain melanosomes  . The number, size and darkness of melanosomes per pigment cell determines skin colour. It appears that, like the golden zebra fish, light-skinned Europeans also have a mutation  in the gene for melanosome production. This results in less pigmented skin. However, Keith Cheng, leader of the research team, points out that the mutation is different in human and zebra fish genes. Humans acquired dark skin in Africa about 1.5 million years ago to protect bodies from ultra-violet rays of the sun, which can cause skin cancer. But when modern humans leave Africa to live in northern latitudes, they need more sunlight on their skin to produce vitamin D. So the related gene changes, according to Cheng. Asians have the same version of the gene as Africans, so they probably acquired their light skin through the action of some other gene that affects skin colours, said Cheng. The new discovery could lead to medical treatments for skin cancer. It also could lead to research into ways to change skin colour without damaging it like chemical treatment done on Michael Jackson. Options: A The version of the pigment gene of Asians and that of Africans are the same. B Scientists have succeeded in turning the colour of a dark-striped zebra fish into uniform gold. C Dark skin can protect bodies from utral-violet rays of the sun. D People like pop king Michael Jackson. Answer: D People like pop king Michael Jackson. Question:

Problem: Write a multi-choice question for the following article, with the given choices and answer: Article: Right is right. Right? Of course. But is left wrong? Well, the Romans used to think so. They thought left-handed people were mistakes of nature. Latin, the language of the Romans, had many words that expressed this view. Some words we use today still have this meaning. The Latin word "dexter" means "right". The English word "dexterous" comes from this word. It means "handy" (clever with hands). So, right is handy. But the Latin word for left is "sinister". The English word "sinister" comes from this word. Sinister means "evil" (very bad). Is it fair to call right-handed people handy and left-handed people evil? Well, fair or not, many languages have words that express such beliefs. In old English, the word for left means "weak". That isn't much of an improvement over "evil". Not very long ago, children were often forced to write with their right hands. Doctors have since found that this can be very harmful. You should use the hand you were born to use. People who use their left hands are just starting to get better treatment. But why they get all these bad names in the first place? One reason may be that there are not as many left-handed people as there are right-handed people. There is one left-handed person for every five right-handed ones. People who are different are often thought to be wrong. But attitudes do seem to be changing. Fair-minded right-handed people are finally starting to give left-handed people a hand. Options: A He can only use his right hand. B He can only use his left hand. C He can use either his left hand or his right hand. D He can use both his left hand and his right hand. Answer: C He can use either his left hand or his right hand. Question:

A: What does the passage lead us to believe when one writes?


Problem: Write a multi-choice question for the following article, with the given choices and answer: Article: Unemployment in the United States is still high at 6.7 percent. But for job seekers,especially those with college educations,researchers say finding a job can be as easy as logging on to a computer.It used to be that looking for a job meant hurrying around,knocking on doors and turning to ads.But that's changing,thanks to the Internet.A new report says,for college graduates,looking for a job is getting easier.More than 80 percent of the jobs are available online. At the height of the depression ,when U.S.unemployment peaked at 10 percent,just a little more than two million jobs were being posted each month.But as the recovery takes hold,the job picture looks increasingly bright. That's great news for Hamilton.Only once has he ever applied in person for a job at a shopping mall. He said,"I think my generation--the idea of going door to door, out knocking and saying,hey are you hiring? --like that--doesn't exist anymore...those days are gone, Just go online.'' Kim Dancy recently graduated with a master's degree in Public Policy.She found her dream job as an education policy researcher.But she says finding the perfect job online takes a lot of perseverance.He said,"It can be really frustrating and it takes a long time,but if you applied for enough positions and really do your homework you will get somewhere. The report's findings suggest careers in Science,Technology,Engineering and Math provide the greatest opportunities,with salaries that range between  $30 to  $45 an hour.But for maximum income and satisfaction,workers must be prepared to move and change jobs at least every five years. Options: A By switching jobs regularly. B By sticking to your work. C By surfing the Internet. D By hurrying around. Answer: A By switching jobs regularly. Question:
