Read the excerpt from "Opening Ceremonies of the New York and Brooklyn Bridge" by Hon. Seth Low, Mayor of the City of Brooklyn. At either end of the Bridge lies a great city--cities full of vigorous life. The activities and the energies of each flow over into the other. The electric current has conveyed unchecked between the two the interchanging thoughts, but the rapid river has ever bidden halt to the foot of man. It is as though the population of these cities had been brought down to the river-side, year after year, there to be taught patience.

Which of the following best summarizes the excerpt?

Both of the cities that lie at the ends of the bridge are great and full of energy.
The people of Brooklyn and Manhattan have been very patient during the construction.
Finally, the people of Brooklyn and Manhattan will be able to connect with each other.
The connection between the two cities has been hampered by the river that divides them.
