hey :) I was wondering... because I have this question which says, ". According to the text, the world’s first important railroad, completed in 1830, ran between what two cities?" And I originally thought it was London and Manchester but we already turned in our books and online it says "manchester and Liverpool" so which is it? If either at all.. ? thanks so much :)
