해석좀 해주실수 있나요 ? 만점마무리 듣기대본인데 ...ㅠ
Today our living conditions are facilitated by this. This is very useful but dangerous at the same time, so only qualified experts can manage this. Thousands of miles of highways, railroads, and waterways are built with the help of this. For example, huge rocks are blasted to make way for highways and railroads. Rocks in the water are removed by this to secure safe waterways for ships. This is also used to mine the many minerals we cannot do without. Even in the city, this is frequently used to dig foundations for buildings. Unfortunately, however, this has also been misused in many wars in the world.
