A human-like robot that can drive a car could one day be used as a chauffeur, though its creator admits that this may take at least 50 years.

Most driverless cars work very differently to a human driver, using artificial intelligence and custom mechanical systems to directly move the steering wheel and pedals. This approach is much more efficient and simpler than using a robot to drive, but it is also specially made for each particular car.

Kento Kawaharazuka at the University of Tokyo and his colleagues have developed a human-like robot, called Musashi, that can drive a car in the same way as a human. It has a human-like “skeleton” and “musculature”, as well as cameras in each of its eyes and force sensors in its hands and feet. Artificial intelligence systems work out what actions are needed to drive the car and react to events that often happen on roads such as traffic lights changing colour or a person stepping in front of the car. The robot can only perform a limited range of driving tasks at present, such as going forward in a straight line, taking a right- hand turn, and moving at speeds of around five kilometres per hour on non-public roads. “The speed of the pedal or the velocity of the car is not high. Also, the handling of the car is not fast compared to human beings,” says Kawaharazuka.

It seems that a robot at the controls of a car, operating in real traffic conditions and in total safety, is not something we are likely to see soon. As mentioned earlier, it could be decades before a robot could really step into the driver’s seat.

Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct word or phrase that best fits each of the numbered blanks.

I was an MBA student in the USA and I lived in the university’s coed dormitory. In my culture, usually, if a woman talks to a man, it is a sign of romantic interest. (34)_____, in the first few days of school, I found it strange that so many women were talking to me and I was under the impression that some women on my dormitory floor were interested in me. To (35)__________ their politeness, I would buy   them flowers or offer small gifts, as is done in my country. However, I was quite surprised to see that these same women now  seemed (36)______around me. One was even quite offended and told me to leave her alone. Eventually I talked to the residence adviser on my floor to see what I was doing wrong, and he explained to me the way men and women usually interact in the USA. I was quite relieved to hear that (37)____ was wrong with me, but rather with the way I was interpreting my conversations with    women. Even though I did not find the love of my life while I was in the USA, I still made many good female friends afterwards (38)______I still maintain contact.

Read the following passage about Life in The Future and mark the letter A, B, C or D on your answer sheet to indicate the best answer to each of the following questions from 23 to 30.

In the near future, technology is expected to bring about significant changes to how we lead our lives. One of the most notable shifts will be the way we keep up with the rapid pace of technological advancements. With smart homes and autonomous vehicles, our daily routines will increasingly depend on sophisticated systems designed to make our lives easier. For example, smart assistants will look out for our needs, such as ordering groceries, adjusting room temperatures, or even scheduling doctor’s appointments.

Another major development will be in communication. Today, we already use video calls to stay in touch with friends and family across the globe, but the future promises even more immersive experiences. Virtual reality could allow us to hang out with people in virtual spaces, regardless of where they physically are. As a result, geographical barriers will become less relevant, creating a more connected and global society.

Healthcare is also likely to transform. Advances in artificial intelligence will enable doctors to look after patients more efficiently, diagnosing diseases earlier and prescribing personalized treatments. These changes may extend our lifespan and improve our quality of life. Additionally, breakthroughs in renewable energy will play a key role in sustaining our future. With green energy sources, such as solar and wind power, we can cut down on harmful emissions and move toward a more sustainable planet.

While these advancements sound exciting, they also bring challenges. As technology becomes more integrated into our lives, we must be careful to ensure privacy and security. We need to watch out for potential risks, like data breaches and the misuse of personal information. With thoughtful planning, however, the future holds great promise for improving the way we live, work, and interact with the world.
