Final answer:
A flow chart is the best tool to understand the sequential process of electing a president, which includes primaries, the general election, and the Electoral College.
Step-by-step explanation:
A flow chart will help you to understand how a president gets elected through the general election process. The election of a president in the United States is a detailed process that includes several stages such as the primaries and caucuses, party conventions, the general election, and, finally, the Electoral College. A flow chart is most useful in illustrating this process because it can show the sequence of steps and decisions that lead to the final outcome, making it an excellent tool for visualizing complex processes.
