Question

what happened on july 28, 1795, during the french revolution?
robespierre was arrested.
the bastille was stormed.
the directory was adopted as a new constitution.
king louis xvi was executed.

Explanation:

On July 28, 1794 (not 1795), Robespierre was arrested and executed. The storming of the Bastille occurred on July 14, 1789. King Louis XVI was executed on January 21, 1793. The Directory was indeed adopted as a new form of government (not exactly a "constitution" in the modern sense but a governing body) in 1795, which aligns with the date in the question.

Answer:

The Directory was adopted as a new form of government (the orange - colored option).
