[19 ～ 20] 밑줄 친 부분에 들어갈 말로 가장 적절한 것을 고르시오. From AI crafting emails, to AI systems recommending TV shows and even helping diagnose disease, the presence of machine intelligence in everyday life is no longer science fiction. And yet, for all the promises of speed, accuracy and optimization, there’s a lingering discomfort. Some people love using AI tools. Others feel anxious, suspicious, even betrayed by them. Why? The answer isn’t just about how AI works. It’s about how we work. We don’t understand it, so we don’t trust it. Human beings are more likely to trust systems they understand. Traditional tools feel familiar: you turn a key, and a car starts. You press a button, and a lift arrives. But many AI systems operate as black boxes: you type something in, and a decision appears. The logic in between is __________. Psychologically, this is unnerving. We like to see cause and effect, and we like being able to interrogate decisions. When we can’t, we feel disempowered.
