What role do the states play in the united states amendments process?

The constitution provides that an amendment may be proposed either by the Congress with the two-thirds majority vote in both the House of Representatives and the senate or by the constitutional convention called by the two-thirds of the state legislators.

Do you have more info about it ? i doubt this is the answer because i don't have all the information but if trouble was brewing in a clinic maybe it was an argument as to which clinic was better or smth of that nature
