Correct answer: A. 5 May 1789
Explanation: The direct answer is option A: the Estates-General began on 5 May 1789. The Estates-General represented the three estates of French society: clergy, nobility, and the Third Estate. Louis XVI called it because the monarchy needed approval for new taxes during a financial crisis. Step by step: the government faced debt and shortage of money; the king summoned representatives; the formal meeting opened on 5 May 1789; disagreements about voting and representation then helped the revolutionary crisis grow. Option A is correct because it gives the date on which the meeting officially began. Option B, 14 July 1789, is wrong for this question; it is the date when the Bastille was stormed. Option C, 4 August 1789, is wrong; it is associated with the abolition of feudal privileges. Option D, 20 June 1789, is wrong as the starting date; it is the date of the Tennis Court Oath, when representatives of the Third Estate pledged not to separate until a constitution had been established. These dates are close together, so confusing them is a common mistake. Memory cue: 5 May meeting, 20 June oath, 14 July Bastille, 4 August feudal privileges.
