[O] Some scientists predict that computing will eventually be based on light. Computer engineers could create devices that use light beams instead of silicon chips. Light could become the main power source for long-distance space travel. The spaceship would have an ultra-thin sail to catch the "wind" of light beamed from an Earth-based laser. In theory, such a craft could accelerate to a sizable fraction of the speed of light without carrying fuel. In paragraph O, why does the author place quotation marks (" ") around the word wind? Group of answer choices to express the author's surprise that wind could be useful for space travel to indicate that the word wind is directly quoted from another magazine to emphasize that the wind in the article is actually light, not moving air to show that the author is not sure if this method of propulsion will work
