If a Memory Is Like a City You Want to Travel

If a memory is like a city you want to travel to and the retrieval paths you use to find the memory are like highways that lead to that city, which is the best strategy for memorizing?

A) build one really big highway, so you are more likely to find the answer later
B) build many highways that travel in many directions, so you have multiple ways to remember it later
C) build toll roads (premium highways) so you can get to the memories as fast as possible with little traffic
D) invest very little in building highways because you never know which highway will be the best road in the future
