Help! Several words were lost while moving sentences from Wikipedia's article on the United States to this quiz. Fill in the blanks to restore these sentences.
Great quiz! As a suggestion though, could you accept railroads for railways? I know it's not the exact word, but it's similar enough. It also might prevent the score for that clue from being so low (after trying railroads, I assumed it was something entirely different and didn't get it in the end).
