When people are asked about the most important discoveries or inventions made in the last two hundred years, they usually mention something very obvious, like the computer or the cell phone. But there are thousands of other discoveries or inventions that have had a huge impact on how we live today. What scientific discovery or technological invention from the last 200 years-other than computers and cell phones-would you choose as being important? Why?
Student A
I mean, we're so used to science and technology that we are not even aware of all the things we use in our daily lives. I would probably choose space satellites. This technology happened in the last hundred years, and it has become important for so many things. Just think about navigation, or telecommunications, or even the military.
Student B
I am thinking about medical progress. Like, for example,when scientists discovered things about healthy nutrition. I am thinking of identifying all the vitamins we need to stay healthy. l am not sure exactly when the vitamin discoveries happened, but I know they are very important. Our health is much better than it was 200 years ago.
User Samples & Evaluation Results

When talk about inventions that have greatly impact our lives, what first come to my mind is the modern transportation. In the past it takes months and even years for people to travel to another country. And it will take a lot of money for people to do so, thus not everyone could afford it. But nowadays you just need to buy a plane ticket which most people can afford and you can arrive at any destination within a day. It is the fact that many industries are benefited from the well developed transportation system. For instance, tourism industry without planes and vehicles wouldn’t be as prosperous as today’s tourism industry because people can’t travel a place to another easily. Additionally, mainly as a result of the well developed transportation system, retailers save a lot of time and money spend on transportation, as the modern transportation is cheaper and faster. Transportation has substantially boosts social productivity by making it convenient for people and goods to transport to a place. Without transportation global economics wouldn’t develop so fast.
