frlit1-10, Exercise 1: Three moments

Model answer (examples):

Calas affair: Voltaire ran a campaign of pamphlets and wrote a treatise on tolerance, which helped overturn an unjust execution; the risk was the displeasure of the authorities and church.
Coup of 1851: Hugo opposed the new emperor and chose about eighteen years of exile on the Channel Islands rather than keep silent; the cost was his home and country.
Dreyfus affair: Zola published J'accuse in 1898, was convicted of libel and left for England to avoid prison; the cost was his position and safety.

Any three are acceptable. Check the dates against a reference work.
