It highlighted the need for revision of the Articles of Confederation.

Explanation:

Let's go back in time for this one. Shay's Rebellion happened in our history due to the problem of debts and poor farmers. Just around the same time, the Articles of Confederation was released, giving us our first lawmaking document. However, the Articles of Confederation had some really poor decisions regarding money and how local/state governments would be able to handle it. One of these problems was regarding the forcing of state governments to collect taxes from their citizens, which frustrated a lot of the poorer citizens, most of them being farmers. Shay's rebellion shows us that the Article of Confederation was very weak in managing a big nation and that there was a need for revision, which leads us to our current lawmaking document, the Constitution.
