I have one last question on my homework. I will give 15 points to whoever answers it first and correctly.

City planners are breaking ground on a new city that many people are hoping will become an important ocean port for trading. Learning from the example of New Orleans, Louisiana, which geographic factor should the city planners pay the most attention to for the future safety of the city?


the city's proximity to a body of freshwater


the city's access to a nearby major railroad hub


the depth of the city's harbor for large barges


the city's elevation above or below sea level


Please hurry.
