Read the passage.With my backpack full of notes about my essay and borrowed books, I trudged through the slush to the library. After months of note-taking, I was eager to compose my thesis.The library’s fourth floor housed a computer lab, and I could hear the hum of fifty computers as I exited the elevator. Unfortunately, there were no available computers, and among the political posters on the wall, a makeshift list had been added for people awaiting a turn at a computer. I added my name to the list and considered returning to the typewriter in my dorm room.
