Task: Question Generation
Input (English): The Parliament of Estonia (Estonian: Riigikogu) or the legislative branch is elected by people for a four-year term by proportional representation. The Estonian political system operates under a framework laid out in the 1992 constitutional document. The Estonian parliament has 101 members and influences the governing of the state primarily by determining the income and the expenses of the state (establishing taxes and adopting the budget). At the same time the parliament has the right to present statements, declarations and appeals to the people of Estonia, ratify and denounce international treaties with other states and international organisations and decide on the Government loans.
Output (English): What year did the Estonians create a constitutional document for their modern political system?
