How old are the two sisters?Deselect Answer 15 and 9 years old 16 and 8 years old they are twins 14 and 10 years old 13 and 11 years old Q. 17 A new study conducted for the World Bank by Murdoch University's Institute for Science and Technology Policy (ISTP) has demonstrated that public transport is more efficient than cars. The study compared the proportion of money poured into transport by thirty-seven cities around the world. This included both the public and private costs of building, maintaining and using a transport system.The study found that the Western Australian city of Perth is a good example of a city with minimal public transport. As a result, 17% of its wealth went into transport costs. Some European and Asian cities, on the other hand, spent as little as 5%. As a consequence, these more efficient cities were able to put the money saved into attracting industry and jobs or creating a better place to live.Professor Newman, ISTP Director describes Melbourne as two cities: "A European city surrounded by a car-dependent one''. Melbourne's large tram network has greatly reduced car use in the inner city, but the outer suburbs have the same car-based structure as most other Australian cities. The increasing demand for accommodation in the inner suburbs of Melbourne suggests that people now prefer to live there.Newman believes there is a new, more general way of considering public transport issues. In the past, environmental and social justice were considered before economics. Newman, however, thinks the study demonstrates that "the auto-dependent city model is inefficient and very inadequate in both economic and environmental terms''.Supporters of the road networks often reject the models of cities with good public transport by saying that these systems would not work in their particular city. One objection is climate. Some people say their city could not make more use of public transport because it is either too hot or too cold. Newman rejects this, pointing out that public transport has been successful in both Toronto and Singapore and, in fact, checks have demonstrated no correlation between the use of cars and the climate.When it comes to other physical characteristics, road lobbies are in a stronger position. For example, Newman accepts it would be hard for a city with a lot of hills like Auckland to develop a really good rail network. However, he points out that both Hong Kong and Zurich have managed to make a success of their rail systems, even if they have more hills than most cities in the world.In fact, Newman believes the main reason for choosing one sort of transport instead of another is politics: "the more democratic the process, the more public transport is favored". He considers Portland, Oregon, a perfect example of this. Some years ago, the central government decided to finance the construction of a new road. However, local pressure groups called for a referendum and the money was spent on a railway instead, which worked extremely well. In the years that have followed, more and more rail systems have been put in, dramatically changing the nature of the city.In the UK, travel times to work had been stable for at least six centuries, and people generally avoided spending more than half an hour travelling to work. Trains and cars initially allowed people to live at greater distances without taking longer to reach their destination. However, public infrastructure did not grow with the increase in urban areas, and this caused enormous congestion problems and much longer commuting times.Many think that if people have more money they want to live further from the city centre where cars are the only practical means of transport. The example of European cities contradicts that. People are often wealthier than their American counterparts but do not use their cars as much. In Stockholm, car use has actually fallen in recent years as the city has become larger and wealthier. New studies show that developing cities in Asia, such as Jakarta and Bangkok, make more use of the car than wealthy Asian cities such as Tokyo and Singapore. In cities that developed later, the World bank and Asian Development Bank discouraged the building of public transport and people have been forced to depend on cars -- creating the massive traffic jams that characterize those cities.An alternative proposal is to convert cities that have been built for cars to rail use, by creating urban villages at hundreds of sites, mostly around railway stations. In the study Melbourne emerges as Deselect Answer a European city a place where people prefer to live a city with a growing demand for car parks a city with an efficient outer suburban tram system a city where people use two opposing modes of transport Q. 18 The use of private transportDeselect Answer has caused enormous traffic problems in Singapore has created hundreds of urban villages is more common among rich Europeans was supported in some Asian cities by banks has increased recently in Stockholm Q. 19 The ISTP report showed that cities with well-developed public transportDeselect Answer spent less money on transport spent more money on transport offered people better jobs were a good example to other cities were less well-organized Q. 20 Some people who prefer travelling by car do not agree with an increase in public transport becauseDeselect Answer it is bad for the environment it didn't work in Hong Kong and Zurich it didn't work in Toronto and Singapore there aren't enough hills in their cities it is not compatible with typical weather conditions Q. 21 In the case of Portland, the most significant aspect governing the choice of trains wasDeselect Answer the building of more roads government decisions financial issues the demands of the inhabitants dramatic changes in the city Q. 22 Which of these diagrams illustrates the correct relationship between: EVEN NUMBERS - MULTIPLES OF 12 - MULTIPLES OF 6?Deselect Answer Figure 5 Figure 3 Figure 4 Figure 1 Figure 2 Q. 23 The product of 40 integer numbers is positive.

If you reopen it after 1 hour, what do you find?Deselect Answer some mass of ice has melted so there is more than 1 kg of water and less than 1 kg of ice that the ice has completely melted and therefore there are 2 kg of water a 0⁰c that the water has solidified and therefore there are 2 kg of ice cannot be answered, because the answer depends on the outside temperature which is not known that nothing has changed: there is always 1 kg of water and 1 kg of ice Q. 33 During a succession of thermodynamic transformations a gas absorbs from the outside a quantity of heat Q _{1} = 10000 J, it gives off a quantity of heat |Q _{2} | = 3000 J and does work L = 2000 J.
