Suppose you are using the second map in Figure, which shows main highways only. You’ve reached a conclusion about the fastest way to drive from the Boston city center to an area south of the city. State whether each of the following assumptions of the map would be a simplifying or critical assumption for your conclusion, and explain briefly. (Don’t worry about whether the assumption is true or not.)

a. The thicker, numbered lines are major highways without traffic lights.

b. The earth is two-dimensional.

c. When two highways cross, you can get from one to the other without going through city traffic.

d. Distances on the map are proportional to distances in the realworld.
