Read the following passage and choose the correct answer to each of the questions from 34 to 40.

1. Since the birth of the car in 1886, transport in big cities has changed a lot. It is no wonder many experts think that there will be extraordinary changes in the next few decades.

2. As technology develops, highways, skylines, subways will be all transformed. Smarter roadways and highways in cities outfitted with IoT sensors will process all kinds of data in real time and inform users of the best transport options. Weather, crashes, traffic conditions will be communicated to users and smart stops will be found everywhere providing renewable energy, green hydrogen or even greener energy, ensuring efficiency and safety on every highway. Tunnels will also be a smart choice because of the reduction of traffic congestion. Underground roads will be built in 3D with a lift system which will take vehicles deep underground and will allow traffic to attain the greatest speed without intersections.

3. There will also be innovations in the sky. Air taxis are not a new idea, but in the future they will be completely environment-friendly. Aviation gasoline will be no longer used. Green energy will be in place and cost-effective air taxis will enable people to travel from one busy urban city to another in record time.

4. New technologies such as AI and the rollout of 5G will pave the way for fully autonomous innovation. Cars will not be the only thing to go autonomous. Freight trucks, cargo vehicles, air taxis will all benefit from this technology and that is why the term 'driver' will become extinct.

5. Transport will go green. Electric or hydrogen power will be mainstream. There will still be issues to solve such as safety, speed and cost, and of course governments will need to make new traffic laws.

 

The word they in paragraph 3 refers to __________.

A large number of inventions require years of arduous research and development before they are perfected. For instance, Thomas Edison made more than 1,000 attempts before successfully inventing the incandescent light bulb. (I) History is replete with examples of inventors failing repeatedly before eventually succeeding. (II) However, not all inventions are the result of relentless effort. (III) Indeed, some inventions come about entirely by accident, often when inventors are attempting to create something else. (IV) These accidental discoveries have profoundly impacted the world, proving that innovation sometimes relies as much on luck as on determination.

In the 1930s, chemist Roy Plunkett was trying to create a new substance for refrigeration. He mixed chemicals, placed them in a pressurized container, and cooled the mixture. The result was not a refrigeration material but Teflon, a substance now widely used to make nonstick cookware. Decades earlier, John Pemberton, a pharmacist in Atlanta, sought to create a tonic to relieve headaches. Though unsuccessful in his original goal, he inadvertently invented Coca-Cola, which became one of the most popular beverages in the world. Both Plunkett and Pemberton demonstrate how unintended outcomes can lead to groundbreaking products.

Accidental discoveries have also played a critical role in scientific advancements. In 1928, Alexander Fleming discovered penicillin, the first antibiotic, when he noticed that mold in a petri dish killed surrounding bacteria. This groundbreaking discovery has saved millions of lives and revolutionized medicine. Similarly, in 1946, Percy Spencer was experimenting with microwaves when he realized that a candy bar in his pocket had melted. Investigating further, he developed the microwave oven, a device that forever changed the way people prepare food.

These stories highlight the unpredictable nature of innovation. While persistence and hard work are often necessary, chance can also play an important role in shaping the modern world. Whether through deliberate effort or serendipity, accidental inventions have transformed industries, improved daily life, and opened new possibilities for the future.
