Generations have been attracted by this toy that lets children and adults alike create anything and everything. But with over 200 millions sets being sold a year in over 100 countries, the question remains -- where did Lego actually come from? Lego was born from the creative mind of Danish carpenter , Ole Kirk Christiansen, back in the early 1930s. He established a small business in Denmark. He and his team built a variety of household goods like ironing boards along with wooden toys. The Lego name was adopted in 1934, formed from the Danish words "Leg Godt" or "play well", which means "I study" or "I put together" in Latin. Christiansen's company continued to make wooden toys until 1942 when fire struck -- the entire Lego factory burned to the ground. Unwilling to give in, the factory was rebuilt and the production line restarted soon after. By 1954, Christiansen's son, Godtfred, had become the junior managing director of the Lego Group. It was during his conversation with an overseas buyer that he was struck by the idea of a toy system. For over 30 years, the Lego Company made only toys and related goods. Then, in 1968, the company opened its first Legoland in Denmark. Combining the Lego building bricks with a computer, the Robotics Invention System 1.5 is now the most advanced toy in the Lego Company, which is targeted at users aged twelve and above, and that includes any parents or grandparents that want to join in. Now the Lego Company is expanding its production lines to include lights, cameras and so on. Lego Company has done a lot to entertain many children around the world. Question: Which of the following is NOT true about the Robotics Invention System 1.5? - It is the most advanced toy in the Lego Company. - It combines the Lego building bricks with a computer. - It is intended for users aged twelve and above. - It is the most expensive toy invented since 1968.
It is the most expensive toy invented since 1968.

Read the following article and select the best answer. Article: British paychologists have found evidence of a link between excessive Internet use and depression, a research has shown. Leeds University researchers, writing in the Psychopathology journal, said a small part of Internet users were classed as Internet addicts and that people in this group were more likely to be depressed than non-addicted users. The article on the relationship between excessive Internet use and depression is from a questionnaire-based study of 1,319 young people and adults. The respondents answered questions about how much time they spent on the Internet and what they used it for; they also complete the Beck Depression Inventory---a series of questions designed to measure the seriousness of depression. The six--page report, by the university's Institute of Psychological Science, said 18 of the people who complete the questionnaire were Internet addict."Our research indicates that excessive Internet use is associated with depression, but what we don't know is which comes first--are depressed people drawn to the Internet or does the Internet cause depression?" the article's lead author Dr Catriona Morrison said."What is clear is that, for a small part of people, excessive use of the Internet could be warning signal for depressive tendencies." The age range of all respondents was between 16 and 51 years, with an average age of 21.24. The average age of the 18 Internet addicts was 18.3 years. By comparing the levels of depression within this group to that within a group of 18 non--addicted Internet users, researchers found the Internet addicts had a higher chance of developing depression than non-addicts. They also discovered that addicts spent more time visiting sexually pleasing website, online gaming sites and online communities. "The public speculation was further proved by this study. That's to say, over-engaging in websites which serve to replace normal social function might be linked to psychological disorders like depression and addiction," Morrison said."We now need to consider the... Question: According to Dr Catriona Morrison, the public speculation _ . - lacks scientific evidence - helps clarify their study - finds a theoretical basis - has little scientific value
finds a theoretical basis

Read the following article and select the best answer. Article: When it comes to social behaviour,mammals are in a league of their own.Some birds may form pairs,or even cooperate to hunt,but the complexity of their relationships can hardly compare to those within a school of dolphins,a herd of elephants or a group of humans.What makes mammalian social groups different from a flock of starlings or a shoal of fish,is that in many cases the individuals could recognize each other.Although we may think that all elephants look pretty much the same,we can easily tell individuals of our own species apart and it has become clear through studies that the same is true of other species.Dolphins have their own signature whistles that act like "names",and elephants can recognize and greet other individuals they have known but not seen for many years.This is something that only a few species of birds appear to be able to do. Mammals in complex social groups not only recognize each other as individuals,but also they remember a lot of information about that individual.Social groups often rely on this memory--such as knowing who is dominant to whom,who is related to whom,and who has done what to whom in the past.It's like remembering who you have lent money to or done a favour for,and who hasn't repaid that money or has talked about you behind your back.You have to learn who to trust,who your friends are,and who to watch out for. All this remembering goes on in a particular part of the brain called the neocortex .If you compare the size of a mammal's social group with the size of this part of the brain,you will find they are remarkably closely related.This area seems to take a long time to develop fully and animals in which it is very large take a very long time to grow up to adulthood.During this time,the youngster has to learn all the rules of social behaviour in their group and to piece together all the relationships between the group members:Knowledge that will be needed to avoid getting into trouble. Question: If the neocortex is larger,the animals _ . - can live a longer life - have a smaller social group - have a larger social group - have a greater body size
have a larger social group
