Answer: 2. They are unrealistic and are therefore unachievable.
Explanation:
Harold Marshall begins this speech by stating that he does have any idealistic promises that will magically fix the city. He states that he is simply a normal citizen and like the rest of the people has heard those promises before from previous mayoral candidates.
Explaining why he does not have such promises for the people, he states that every mayor that has promised them has receded into the annals of history without taking them any closer to the goals they promised. This paints a picture of a man who believes that those goals were unrealistic and by extension unachievable.
Not too sure, but I take it that the book satisfies his need for imagination temporarily, but also awakens a tier of satisfaction to be met, be it for more imagination or not.
