[4] Read the instructions and write a well-organized answer in English. (50 points) Virtual reality (VR)* refers to a high-quality simulation of reality created by a computer. Probably the most famous use for VR so far is gaming. But VR has also been used to improve society in various fields such as education, medicine, and engineering. Describe a single specific way that virtual reality can be used to improve society. Explain your idea in detail in about 100 English words. Notes: Virtual reality (VR)*: VR systems use special glasses that completely cover the user's eyes. These glasses show a very realistic picture of a world created by the computer.

If they do this, Students who want be surgeon in the future will reduce about operation's anxiety. In this way, VR have a lot of possibilities that useful of medical field. For these reasons, I suggest VR simulations.
