Computers have changed quite a bit through the years in early model could at 18 million numbers per hour one person could have needed many years to do the same job a modern computer could add one and a half trillion numbers in less than 3 hours. what is the main idea? a. who uses computers. b. how long one person takes to do a job. c. how computers have gotten faster overtime. d. how fast modern computers can add.

C and D, I f I had to choose one, then I'd go with C because D is redundant. If computer have gotten faster over time, then it's inherent that a modern computer would be faster than a previous one, hence computers have gotten faster over time. C

idk i just need the points

emerson essentially believes that traveling is overrated. he supports this perspective through an initial focus on "the idea" of places like italy, england, and egypt, and the fascination of "educated americans" with them. he argues that those places only took on the grand, majestic ideas that they represent because "they who made england, italy, or greece venerable in the imagination did so by sticking fast where they were, like an axis of the earth." yes, those places are grand, but only because they so clearly represent the places that they are. the art and culture of italy, england, and egypt is authentic, and therefore significant.
