Host: Interesting! Will the internet help improve the environment
Dr Li: Yes! As more things become connected to the internet, our cities will
become smart cities. Smart cities will be more eco-friendly than cities
today. One of the most important changes will come in energy use.
Different devices will communicate and share data with each other.
This will help them save energy. For example, smart rubbish bins will
automatically tell the smart city network when they are full. This data
will allow the rubbish collection company to plan better collection routes.
According to Dr. Li, compared to cities today, smart cities will be ______:
A) more crowded. B) less connected.
C) more eco-friendly. D) less safe.

Host: Will smart cities improve our lives in other ways
Dr Li: I think the biggest change will be in transport. Our roads will be much
safer in the future, and traffic will flow more smoothly. There will be
fewer accidents because cars will drive themselves, and they will
share data with the smart city network. With this data, traffic lights
can change the timing according to the number of cars on the road.
Host: That’s amazing. And will this really be possible
Dr Li: Yes, it will. We’ve already started doing some of these-things!
What is presented as the "biggest change" that smart cities will bring to our lives in other ways, besides the environment
A) Improved education.
B) More job opportunities.
C) Changes in transport.
