Answer:
Creation of political factions
Step-by-step explanation:
In these lines, Washington talks about the "spirit of party." This refers to the feelings that are developed among people when they are divided into groups (factions or political parties). Washington argues that when this happens, negative feelings arise among the population, including feelings of jealousy, false alarm, animosity, riots and insurrection. Therefore, Washington wants to warn the public about this, and ask them to be careful of this risk.
