"How the Internet and Other Technologies Came About" is a document written by Michio Kaku as part of his bigger book: "Visions: How Science Will Revolutionize the 21st Century", which was published in 1998. The book in general is an exposition by Kaku on the different technological advances that have happened in recent history and that have changed the way things work in the 20th century. He also reflects on how specific areas of science and technology have particularly affected life, like quantum mechanics, artifical intelligence, and others. In this specific excerpt, present in page 46, Kaku is reflecting and speaking about virtual reality and how this particular technological advancement changed the world. He also explains how virtual reality came about, its origin, the reasons for its discovery and success, and its original purpose. The correct answer here then, the most accurate summary to Kaku´s argument would be: that virtual reality started as a tool that was created by the Pentagon as a means to help prepare pilots for a nuclear war.
