Anew and/or improved weapon used in world war i.

question 9 options:

airplanes

gun powder

atomic weapons

explosives

I believe the correct answer is A. or the first option Airplanes.

Explanation:

The first airplane was launched from a moving ship in May of 1912. The planes weren't as technologically advanced and needed to land on the water then be retrieved. So, the technological advancements weren't very well back then at all and Airplanes were one of the first new improved weapons during WW I to be used.

the most famous of all the units fighting in cuba, the "rough riders" was the name given to the first u.s. volunteer cavalry under the leadership of theodore roosevelt. roosevelt resigned his position as assistant secretary of the navy in may 1898 to join the volunteer cavalry. the original plan for this unit called for filling it with men from the indian territory, new mexico, arizona, and oklahoma. however, once roosevelt joined the group, it quickly became the place for a mix of troops ranging from ivy league athletes to glee-club singers to texas rangers and indians.
