Based on the text provided, the opinions that someone could form about the Brooklyn Bridge are:
- People are likely to start moving to Brooklyn.
- Building the bridge was a good idea.
- Commuting to work will probably become easier for people on both sides.
The other two options can be ruled out:
- The bridge will make it hard for people to communicate with Brooklyn. (This contradicts the text, which suggests that the bridge facilitates rapid communication.)
- The bridge was probably built to get rid of fog and ice. (The text suggests that the bridge allows for uninterrupted travel regardless of fog and ice, but it does not imply that the bridge was built to eliminate them.)
