Where once children used to play sports and games together in the street, they now sit alone in their rooms on the computer playing games on the Internet. Where in the past young children learned human interaction from active games with their friends this is no longer the case. How then, when these children are grown up, will they be able to socially interact with their colleagues?Which one of the following is the conclusion of the above statement?Deselect Answer Children who play computer games now interact less outside of them. The Internet can be a tool for teaching social skills. Computer games are for social development. Children should be made to play outside with their friends to develop their social skills for later in life. Adults will in the future play computer games as a means of interaction. Soru 58Between 2006 and 2013 the British government spent 473 million on Tamiflu antiviral drugs in preparation for a flu pandemic, despite there being little evidence to support the effectiveness of the drug. The antivirals were stockpiled for a flu pandemic that never fully materialised. Only 150,000 packs were used during the swine flu episode in 2009, and it is unclear if this improved outcomes. Therefore, this money could have been much better spent on drugs that would actually benefit patients.Which option best summarises the author's view in the passage?Deselect Answer Drugs should never be stockpiled, as they may not be used. Spending millions of pounds on drugs should be justified by strong evidence showing positive effects. We should not prepare for flu pandemics in the future. The recipients of Tamiflu in the swine flu pandemic had no difference in symptoms or outcomes to patients who did not receive the antivirals. We should not use drugs which don't have a good body of evidence to back them up. Soru 59The speed limit on motorways and dual carriageways has been 70mph since 1965, but this is an outdated policy and needs to change. Since 1965, car brakes have become much more effective, and many safety features have been introduced into cars, such as seatbelts (which are now compulsory to wear), crumple zones and airbags. Therefore, it is clear that cars no longer need to be restricted to 70mph, and the speed limit can be safely increased to 80mph without causing more road fatalities.Which of the following best illustrates an assumption in this passage?Deselect Answer The government should increase the speed limit to 80mph. If the speed limit were increased to 80mph, drivers would not begin to drive at 90mph. The safety systems introduced reduce the chances of fatal road accidents for cars travelling at higher speeds. The roads have not become busier since the 70mph speed limit was introduced. The public want the speed limit to increase. Soru 60Children are being encouraged to take up gardening through special events at shows and activities in schools. It is hoped that an interest in gardening, and particularly growing one's own food, will make children more interested in learning about their food and they will therefore be deterred from eating junk food. The initiative should be supported and spread to more schools as quickly as possible. Which one of the following, if true, would most weaken the above argument?Deselect Answer The practical experience of gardening is not a traditional academic subject. The events to encourage children to garden also included stands where junk food was for sale. Some schools do not have a garden. It tends to be older people who are interested in gardening and growing their own food. Most children have enjoyed the events provided, but have not gained an interest in gardening itself.
