Trenches were built during world war 1 for what reason?

A. To protect soldiers from machine gun fire is your best answer

While the Gatling gun had been around since the American civil war, machine guns had involved into more lethal weapons, as they were able to fire thousands of rounds at once, became lighter to carry, and were water-cooled. Trenches essentially was built to protect the soldiers from being massed-murdered by the machine gun. However, this isn't the only reason trenches were built, but one of them.

on 6 november american voters will elect members of the house of representatives and the senate, which together are called congress.

both houses of congress are currently controlled by the republican party, which backs president donald trump.

the democrats think they can win control of the house of representatives this year by winning a majority of seats.

doing so would let them block or delay the president’s plans by refusing to enact them.

all 435 seats in the house of representatives are up for election.

if the democrats want to take control of the house by having the most seats, they’re going to have to claim at least 23 from the republicans.
