Possible answers:
- The Greeks and the Persians
- The Romans and Numidians allied against the Carthaginians and their allies
- The Romans against the Greeks of Macedonia
- The Carthaginians and Egyptians against Rome
Explanation: The Battle of Zama ended the 2nd Punic War. Scipio Africanus, who earned his surname from this victory, had learned tactics from Hannibal himself in order to defeat him. This defeat forced Carthage to accept a humiliating peace and give up its Mediterranean ambitions.
Question 2 : What landmark event in aviation took place on October 19, 1783?
Possible answers:
- The first transatlantic balloon flight
- The first human flight in a hot-air balloon
- The first powered airship flight
- The first parachute jump from a balloon
Explanation: This first human flight in a hot air balloon was carried out by Pilâtre de Rozier and the Marquis d'Arlandes above Paris. The craft had been invented by the Montgolfier brothers, Joseph-Michel and Jacques-Étienne, who had first tested their invention with animals a few weeks earlier.
Question 3 : The Jacobin Club was founded on October 19, 1789. What event in the preceding days led the National Assembly to leave Versailles for Paris?
Possible answers:
- The storming of the Bastille on July 14

- The night of August 4 and the abolition of privileges
- The Declaration of the Rights of Man on August 26
Explanation: On October 5 and 6, 1789, thousands of Parisian women marched on Versailles, forcing Louis XVI and his family to move to Paris. This relocation of the king symbolized a decisive loss of power for the monarchy. The Jacobin Club then became one of the most influential political forces of the Revolution.

Possible answers:
- Lumachrome color photography
- The phonograph
- The cinematograph, co-invented with his brother Louis
- The wireless telegraph
Explanation: Auguste Lumière and his brother Louis patented the cinematograph in 1895 and organized the first paid public screening in Paris on December 28, 1895 at the Grand Café. Auguste also took an interest in biology and medicine, notably developing treatments for scars and cancer.
Question 5 : What stock market crash happened on Wall Street on October 19, 1987?
Possible answers:
- The tech stock crash, known as the dot-com bubble

Question 6 : Subrahmanyan Chandrasekhar, born on October 19, 1910, received the Nobel Prize in Physics in 1983 for his work in what field?
Possible answers:
- Quantum mechanics and particle physics
- The structure and evolution of stars, particularly white dwarfs
- General relativity and the cosmology of the primordial universe
- Nuclear physics applied to reactors
Explanation: Chandrasekhar is famous for calculating the maximum mass a star can have before collapsing into a neutron star or black hole, known as the "Chandrasekhar limit" (about 1.4 times the mass of the Sun). He made this discovery at just 19 years old during a boat crossing to England.
Question 7 : The Polish priest Jerzy Popieluszko was murdered on 19 October 1984. What movement was he closely linked to?
Possible answers:
- The Polish United Workers' Party

- Armed resistance against the Soviet occupation
Explanation: Jerzy Popieluszko was a fervent supporter of the Solidarność (Solidarity) trade union and celebrated widely attended masses for the homeland. He was kidnapped and killed by agents of the Polish communist State Security (SB). His murder sparked international outrage and paradoxically strengthened the opposition movement. He was beatified in 2010.
Question 8 : In 1939, a major French scientific institution was founded on October 19. Which one?
Possible answers:
- The Pasteur Institute in Paris
- The Federal Polytechnic School of Research
- The CNRS, National Centre for Scientific Research
- The CEA, Atomic Energy Commission
Explanation: The CNRS (Centre National de la Recherche Scientifique) was created by decree on October 19, 1939, driven in particular by Jean Perrin, Nobel Prize in Physics. Today it is the largest public fundamental research organization in France, with more than 30,000 people, including 11,000 researchers.
Question 9 : Hannibal Barca, the Carthaginian general defeated at the Battle of Zama, is best known for what other bold military action?
Possible answers:
- The conquest of Egypt and the Nile delta
- Crossing the Alps with elephants to invade Italy
- The founding of the city of Carthage in North Africa
- The circumnavigation of Africa by sea
Explanation: Hannibal crossed the Alps with his army and war elephants in 218 BC, completely surprising the Romans. Before Zama, he had won great victories, notably at the Battle of Cannae in -216, considered one of Rome's greatest military defeats, with around 70,000 Roman soldiers killed.
Question 10 : In 2017, an unprecedented celestial object was discovered and linked to October 19. What was the nature of this discovery?
Possible answers:
- A new dwarf planet discovered at the edge of the solar system
- The first asteroid confirmed as coming from another star system
- A giant comet that grazed Earth by a few million kilometers
- A repeated radio signal picked up from a distant galaxy
Explanation: 1I/ʻOumuamua, whose name means "messenger from afar arriving first" in Hawaiian, crossed our solar system at high speed on a hyperbolic trajectory, confirming its extrasolar origin. Its elongated shape and unexplained acceleration fueled speculation about its nature, with some scientists even suggesting a possible artificial origin, a hypothesis that remains unconfirmed.
