Question

which action could accomplish all of the goals of the french revolution?
eliminating absolute authority
writing a constitution
ending the class system
passing a fairer tax system

Explanation:

The French Revolution aimed to overthrow the absolute monarchy (eliminating absolute authority), establish a more just social order (ending the class system was part of this, but a constitution would enshrine these changes more comprehensively), and have fair governance. A constitution would set the framework for a new government structure, limit authority (addressing absolute authority), and could potentially outline a more equitable social and tax system. While ending the class system or passing a fairer tax system are aspects, a constitution is a more overarching document. Writing a constitution could encapsulate multiple goals of the French Revolution like liberty, equality, and fraternity by providing a legal and structural basis for the new order.

Answer:

writing a constitution
