Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions. In this modern world where closed-circuit television (CCTV) cameras are everywhere and smartphones are in every pocket, the routine filming of everyday life is becoming pervasive. A number of countries are rolling out body cams for police officers; other public-facing agencies such as schools, councils and hospitals are also experimenting with cameras for their employees. Private citizens are getting in on the act too: cyclists increasingly wear headcams as a deterrent to aggressive drivers. As camera technology gets smaller and cheaper, it isn’t to envision a future where we’re all filming everything all the time, in every direction. Would that be a good thing? There are some obvious potential upsides. If people know they are on camera, especially when at work or using public services, they are certainly less likely to misbehave. The available evidence suggests that it discourages behaviors such as vandalism. Another upside is that it would be harder to get away with crimes or to evade blame for accidents. But a world on camera could have subtle negative effects. The deluge of data we pour into the hands of Google, Facebook and others has already proved a mixed blessing. Those companies would no doubt be willing to upload and curate our body-cam data for free, but at what cost to privacy and freedom of choice? Body-cam data could also create a legal minefield. Disputes over the veracity and interpretation of police footage have already surfaced. eventually, events not caught on camera could be treated as if they didn’t happen. alternatively, footage could be faked or doctored to dodge blame or incriminate others. Of course, there’s always the argument that if you’re not doing anything wrong, you have nothing to fear. But most people have done something embarrassing, or even illegal, that they regret and would prefer they hadn’t been caught on film. People already censor their social media feeds – or avoid doing anything incriminating in public – for fear of damaging their reputation. Would ubiquitous body cams have a further chilling effect on our freedom? The always-on-camera world could even threaten some of the attributes that make us human. We are natural gossips and backbiters, and while those might not be desirable behaviours, they oil the wheels of our social interactions. Once people assume they are being filmed, they are likely to clam up. The argument in relation to body-cam ownership is a bit like that for guns: once you go past a critical threshold, almost everyone will feel they need one as an insurance policy. We are nowhere near that point yet but we should think hard about whether we really want to say “lights, body cam, action.” What does the passage mainly discuss?

Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions.A large number of inventions require years of arduous research and development before they are perfected. For instance, Thomas Edison had to make more than 1,000 attempts to invent the incandescent light bulb before he finally succeeded. History is replete with numerous other examples of people trying, yet failing to make inventions before they eventually succeeded. Yet some inventions have come about not through hard work but simply by accident.In most cases, when someone unintentionally invented something, the inventor was attempting to create something else. For example, in the 1930s, chemist Roy Plunkett was attempting to make a new substance that could be used to refract items. He mixed some chemicals together. Then, he put them into a pressurized container and cooled the mixture. By the time his experiment was complete, he had a new invention. It was not a new substance that could be used for refrigeration though. Instead, he had invented Teflon, which is today most commonly used to make nonstick pots and pans. similar, decades earlier, John Pemberton was a pharmacist in Atlanta, Georgia. He was attempting to create a tonic that people could use whenever they had headaches. While he was not successful in that endeavor, he managed to invent Coca-Cola, the world – famous carbonated soft drink. Scientists have also made crucial discoveries by accident when they were conducting experiments. In 1928, Alexander Fleming discovered penicillin, an antibiotic, in this manner. He discovered some mold growing in a dish with some bacteria. He noticed that the bacteria seemed to be avoiding the mold. When he evaluated further, he determined some of the many useful properties of penicillin, which has saved millions of lives over the past few decades. Likewise, in 1946, scientist Percy Spencer was conducting an experiment with microwaves. He had a candy bar in his pocket, and he noticed that it suddenly melted. He evaluated and learned the reason why that had happened. Soon, he built a device that could utilize microwaves to heat food. the microwave oven.In paragraph 2, the word endeavors is closest in meaning to _______.
