Q: Write a multi-choice question for the following article: Article: When we talk about superstitious beliefs , the beliefs associated with Friday the 13th , no doubt , deserve a special mention . In fact , such is the fear associated with this date that people just can't seem to stick to their daily routine on this day . The data from Stress Management Center and Phobia Institute suggests that somewhere around 17 to 21 million Americans are affected by the fear associated with this day , i.e. the combination of Friday and 13 . Even worse , the financial losses caused on this day amounts to as much as US$800 million every year . As we flipped through the pages of history , we realized that Friday the 13th bears the brunt of bad luck associated with number 13 , the unluckiest number , and Friday , the unluckiest day of the week . Number 13 has always been considered unlucky , mainly as a result of it being associated with various occurrences in mythology . While some associate it with the instance of Norse mythology , in which the god of joy and gladness - Balter , was killed in a dishonest manner by Loki - the god of discord and mischief , who was the 13th guest , others associate it with the Last Supper , in which the 13th guest was Judas , who betrayed Jesus to his enemies for 30 pieces of silver . Similarly , Friday has also been a sign of bad luck to many people , with incidents like Jesus being crucified on this unfaithful day , contributing to this belief . It is also widely believed that Cain killed Able on this very day of the week . The fear of Friday the 13th is known as friggatriskaidekaphobia and paraskevidekatriaphobia , the former combining the words frigga , meaning Friday , and triskaidekaphobia , meaning the phobia of number 13 . Over the period , the belief that Friday the 13th is an unlucky day has just become one of the most widely accepted superstitions , which consequently causes much blind panic and unreasonable fear in the world .
A: Question: What is the passage mainly about?Options:A The psychology of superstitionB The history of a common superstitionC The origins of Friday the 13thD Influences of Friday the 13thAnswer:C

Q: Write a multi-choice question for the following article: Article: Can you believe your eyes? A recent experiment suggests that the answer to that question may depend on your age. Martin Doherty, a psychologist at the University of Stirling in Scotland, led the team of scientists. In this experiment, Doherty and his team tested the perception of some people, using pictures of some orange circles. The researchers showed the same pictures to two groups of people. The first group included 151 children aged 4 to 10, and the second group included 24 adults aged 18 to 25. The first group of pictures showed two circles alone on a white background. One of the circles was larger than the other, and these people were asked to identify the larger one. Four-year-olds identified the correct circle 79 percent of the time. Adults identified the correct circle 95 percent of the time. Next, both groups were shown a picture where the orange circles, again of different sizes, were surrounded by gray circles. Here's where the trick lies in. In some of the pictures, the smaller orange circle was surrounded by even smaller gray circles -- making the orange circle appear larger than the other orange circle, which was the real larger one. And the larger orange circle was surrounded by even bigger gray circles -- so it appeared to be smaller than the real smaller orange circle. When young children aged 4 to 6 looked at these tricky pictures, they weren't fooled -- they were still able to find the bigger circle with roughly the same accuracy as before. Older children and adults, on the other hand, did not do as well. Older children often identified the smaller circle as the larger one, and adults got it wrong most of the time. As children get older, Doherty said, their brains may develop the ability to identify visual context. In other words, they will begin to process the whole picture at once: the tricky gray circles, as well as the orange circle in the middle. As a result, they're more likely to fall for this kind of visual trick.
A: Question: According to the passage, we can know that _ .Options:A a smaller orange circle appears bigger on a white backgroundB an orange circle appears bigger than a gray one of the same sizeC a circle surrounded by other circles looks bigger than its real sizeD a circle surrounded by bigger ones looks smaller than its real sizeAnswer:D

Q: Write a multi-choice question for the following article: Article: It seems like every year brings a new outbreak of sickness.Recent research tells us how diseases spread, from person to person.And it also gives us an idea how we can spread something better than diseases. An author called Malcom Gladwell recently published a book explaining how the process works.We usually think of an epidemic as a force of nature that rolls over anyone in its way.In fact, it starts with a single person or very few people.These people travel around and infect small groups in different places.When enough of these groups are infected, then the disease suddenly seems to be everywhere.Gladwell also found that the process of infection was not just limited to disease? It also affects the world of ideas. The process can be seen in books and fashion.So called _ are not pushed towards the public.They spread through hundreds of small reading groups until the day when everybody you know seems to have a copy.A group of young people may decide to wear an item of clothing simply because no one else is wearing it.Designers who monitor street fashion then pick up the idea and spread it.Finally everyone is wearing it. New York is often described as an unfriendly place.People are too busy looking after business to look after each other.In the early 1990s, one unknown person decided to perform at least one kind act a day.This caught on with his or her friends.The newspapers noticed the trend .New York became full of people smiling and carrying each other's bags. The success of trends like this fits in with other social phenomena .One is the 80/20 rule.This was invented by economists who noticed that in any situation 20 percent of the people did 80 percent of the work.Another is the "bystander problem".Psychologists noticed that in accidents where a large number of people were around, no one stepped forward to help.Each person supposed that someone else would do something.When there were less people present, more of them decided to offer help. What all this proves is...
