What was George Washington's fears about political parties and how did his selection of Alexander Hamilton and Thomas Jefferson to his Cabinet address those fears?

He feared polarization and conflict

Explanation:

His thought was that political parties would obstruct the daily duties of the government or the representative's jobs. This could be reflected now and an example would be the government's gridlock and sometimes their decision to put their party over the country's priorities. Hamilton and Jefferson reflected this fear because of their arguments when they served as Washington's cabinet. Their constant conflict resulted in inability to decide in national priorities.
