By 2050 the world’s population is expected to reach 10 billion, and nearly 70 per cent of these people will live in cities. The cities of the future wili be ‘smarter’ and more sustainable to cope with a growing population and improve people’s lives.

A smart city is amodern urban area that uses a range of technologies to provide services, solve problems, and support people better. The new technologies can help save time by predicting changes in the traffic and warning people of possible traffic jams. They will also help cities operate more efficiently. For example, street lights can turn off when the streets are empty, and sensors can inform waste collection teams when the bins are full. These smart technologies will help save energy, reduce air pollution, and fight climate change.

Cities in the future will also be sustainable. They will include a lot of green space and become home to more plants and animals. Making room for biodiversity and nature can be done in various ways including underground and rooftop farming, green roofs, and roof gardens. As people will care more about the environment, most cities will use renewable and clean energy. Modern infrastructure will also be more eco-friendly. Computer-controlled transport systems like electric buses and trains will produce less greenhouse gas emissions. In addition, more pedestrian zones for walking and cycle paths will be made available for people in all neighbourhoods.

These features will make future cities more liveable and will provide a high quality of life to city dwellers.

1. operate more efficiently

A. to work better without wasting time, money, or energy

B. instruments that can be played by people

3. pedestrian zones

Read the following passage and mark the letter A, B, C, or D to indicate the correct answer to each of the question.

The world needs to do more to prepare for the impact of a rapidly ageing population, the UN has warned - particularly in developing countries. Within 10 years the number of people aged over 60 will pass one billion, a report by the UN Population Fund said. The demographic shift will present huge challenges to countries’ welfare, pension and healthcare systems. The UN agency also said more had to be done to tackle "abuse, neglect and violence against older persons".

The number of older people worldwide is growing faster than any other age group. The report, Ageing in the let Century: A Celebration and a Challenge, estimates that one in nine people around the world are older than 60. The elderly population is expected to swell by 200 million in the next decade to surpass one billion, and reach two billion by 2050. This rising proportion of older people is a consequence of success - improved nutrition, sanitation, healthcare, education and economic well-being are contributing factors, the report says.

But the UN and a charity that also contributed to the report, Help Age International, say the ageing population is being widely mismanaged. "In many developing countries with large populations of young people, the challenge is that governments have not put policies and practices in place to support their current older populations or made enough preparations for 2050," the agencies said in a joint statement.

The word "abuse" in the first paragraph could be best replaced by ________.

A. care       

B. protection         

C. insult      

D. prais
