[Q]: Write a multi-choice question for the following article, with the given choices and answer: Article: If you are looking for an animal to take the title of "most violent fish in the sea", then the tiger puffer fish would have to be a strong contestant. Not only is it deadly poisonous --- though that doesn't stop people trying to eat it --- but it is also able to scare off enemies by inflating itself to become much larger than normal, when it is young it even chews on its own brothers and sisters. Tiger puffer fish attach their eggs to rocks near the bottom of the sea, often at the mouths of bays. Then the larvae move to the entries of rivers and lakes once they have grown a little. Then, having put on a lot of weight, they head out to sea. There's no innocent childhood for the puffer fish, as Shin Oikawa of Kyushu University in Japan and his colleagues found out when they put the larvae of tiger puffer fish in the lab and monitored them for two months. They found that the larvae went through three steps in which their metabolic rates increased dramatically when they reached body weights of 0.002g, 0.01g, and 0.1g. When a larva went through one of these steps, its behavior also changed. For instance, once a larva had passed the first level it would have grown its first tooth and could start attacking larvae that had not yet reached that stage. Similarly, any larva that had reached the 0.01g or 0.1g levels would start attacking lighter larvae. The researchers noted that the baby fish had a "relatively small mouth", so rather than swallowing their brothers and sisters whole, they would bite pieces out of them. Despite this limitation, the fish caused plenty of deaths --- up to 12 per cent of the deaths that happened in the lab each day. Those fish that grew fast enough to be able to chew on their fellows had an advantage. The extra food accelerated their growth and development. Tiger puffer fish are likely to be faster and swifter, so they can deal better with enemies. As the name suggests, puffer fish can inflate to make themselves seem much larger than they really are, thus scaring off enemies. They do... Options: A they are very difficult to catch B they can become larger to threaten enemies away C they kill their younger companions as they grow up D they are deadly poisonous Answer: A they are very difficult to catch Question:

[Q]: Write a multi-choice question for the following article, with the given choices and answer: Article: People with mentally taxing jobs, including lawyers and graphic designers, may end up having better memory in old age, research suggests. A study of more than 1,000 Scottish 70-year-olds found that those who had had complex jobs scored better on memory and thinking tests. One theory is that a more stimulating environment helps build up a "cognitive reserve" to help buffer the brain against age-related decline. The research was reported in Neurology. The team, from Heriot-Watt University, in Edinburgh, is now planning more work to look at how lifestyle and work interact to affect memory loss. Those taking part in the study took tests designed to assess memory, processing speed and general thinking ability, as well as filling in a questionnaire about their working life. The analysis showed that those whose jobs had required complex skills in dealing with data or people, such as management and teaching, had better scores on memory and thinking tests than those who had done less mentally intense jobs such as factory workers, bookbinders, or carpet layers. While the study did not look at biological reasons for the protective effect of certain jobs, potential explanations include that structural changes within the brain mean less damage is accumulated over time. Study leader Dr Alan Gow said: "Our findings have helped to identify the kinds of job demands that preserve memory and thinking later on." "However," He added, "while it is true that people who have higher cognitive abilities are more likely to get more complex jobs, there still seems to be a small advantage gained from these complex jobs for later thinking skills." Dr Simon Ridley, head of research at Alzheimer's Research UK, said the study added to the growing evidence about factors that affected brain health as we aged. "Keeping the brain active throughout life could be helpful and different types of work may play a role. However, it's important to note that this study points to a small and subtle association between occupation and later-life cognition... Options: A different occupations may make a difference in keeping the brain active B people's occupation has a direct influence on later-life cognition C the study added more evidence about the factors affecting aging D the study denied the association between jobs and later-life memory Answer: A different occupations may make a difference in keeping the brain active Question:

[Q]: Write a multi-choice question for the following article, with the given choices and answer: Article: For thousands of years, the most important two buildings in any British village have been the church and the pub.Traditionally, the church and the pub are at the heart of any village or town, where the people gather together to socialize and exchange news. As a result, British pubs are often old and well preserved.Many of them have become historic sites.The most famous example is the pub in the city of Nottingham called " Ye Olde Trip to Jerusalem" , which dates back to the year 1189 AD and is probably the oldest pub in England. However, British pubs are not just for kings and queens; they welcome people from all classes and parts of society.On a cold night, the pub's landlord or landlady can always find a warm place for you by the fire.There is always honest and hearty food and plenty of drinks available at an affordable price. That's how things used to be.Things are beginning to change.It is said that the credit crunch is causing 39 British pubs in a week to go out of business.People do not have enough spare money to spend on beer.Recently, the UK government banned smoking in all pubs, and that may also have affected the number of customers going to pubs. This decline is happening despite the fact that in 2005 the UK government started to allow pubs to stay open after 11 p.m..Previously, with 11 p.m.as closing time, customers would have to drink quite quickly, meaning they sometimes got more drunk than they would if allowed to drink slowly.The British habit of drinking a lot very quickly is known as "binge drinking" , and it causes long-term health problems for people and problems with violent crime for communities. In order to save their businesses, pubs are trying to change with the market.British pubs now offer something for everyone.A lot of pubs used to be "Working Men's Clubs" , meaning that women could not usually enter.Today, however, women can freely enter 99% of pubs without experiencing any problems.Perhaps things are changing for the better after all. Options: A the long history of British pubs B the present situation of British pubs C the reason why British people go to pubs D the disadvantages of running pubs in Britain Answer: B the present situation of British pubs Question:
