In what way did industrialization affect the fighting in World War I? A) Trains were used for the first time in modern warfare. B) Mass-produced weapons caused a larger number of deaths than in previous conflicts. C) An economic depression caused a shortage of weapons along the Western Front in France. D) Aircraft carriers allowed planes to strike deep within enemy territory in areas far from land bases.

The correct answer is:

A) and B).

Mass production allowed weapons to be made faster than ever before, including new ones such as moveable machine guns, choline gas, flamethrowers, zeppelins, and torpedoes. At the same time, vehicles such as tanks, planes, and cars were also mass produced, and trench railways were a military adaptation of the railway technology to the problem of keeping soldiers supplied during the static trench warfare phase of World War I.

B) Mass-produced weapons caused a larger number of deaths than in previous conflicts.

Explanation:

Industrialization caused the development of the war industry. Mass production of weaponry gave the country's armies more options for lethal attacks. As a result, the number of deaths was much higher than in previous wars. It is noteworthy that the war industry developed mainly in the US, which became the largest supplier of weapons to European countries.
