pls help
is appreciated :D

The guillotine was a device used to decapitate people, or cut off their heads. The Jacobins used it to execute people who spoke against them. The unlucky person stuck his or her head underneath the blade, and then the executioner let the blade drop down quickly on the neck. Even though the death machine was terrifying and deadly, the guillotine was actually inspired by the Enlightenment. Compared to older execution techniques, such as hanging, burning or the using the breaking wheel, people in revolutionary France considered the guillotine to be a gentler, more humane way to execute people. Either way, people were still killing other people.
King Louis XVI, his wife, Marie Antoinette, and thousands of others who crossed Robespierre met their fate under the blade of guillotine. And the guillotine wasn't just some old historical horror. The French continued to use the guillotine until 1981, when France outlawed capital punishment.

At the time of the French Revolution, the guillotine was considered:
a)The least cruel form of capital punishment.
b)The most painful way to punish criminals.
d) Outdated and inhumane.

Describe how technological advancements changed how WWI was fought and how those technologies impacted the aftermath of the war.

Answers

Technological advancements that were developed pre-ww1 and perfected after the war highly influenced the modern combat of the 20th century. The use of artillery had been massively used from far distances to bombarded enemy lines. New times of guns were used such as the "Maxim Gun" which was one of the first machine guns that allowed the shooter to mow down lines of enemies. Chemical warfare had been used as well being fired from artillery and burning the lungs of enemy troops using gases such as, "Mustard Gas." What was also used were armored trains with canons and machine guns. Tanks were developed during the war by the British such as the "Mark I." Planes were also being weaponized by dropping bombs on battlefields and cities. "Zeppelins" were these massive blimps that also dropped loads of bombs on enemy territory.

After the war these technologies would slowly be developed and improved, some would be trashed away or converted for public use. Examples, the tank was developed to be more light and agile by the Germans and Russian pre-ww2. Zeppelins on the other had were converted as people movers or "airships" that would transfer people across oceans instead of being used for war.
