In the Las Vegas mass shooting, Stephen Paddock used a device called a bump stock, which is designed to

1: muffle the sound of gunfire from an automatic weapon.

2: let a shooter zero in on a target from thousands of yards away.

3:allow a semiautomatic rifle to fire rounds faster.

4: make a rifle lightweight and easier to carry.

can you explain it better

question 1: paragraph 3

question 2: paragraph 2

question 3: paragraph 1

hope this !

can you me on my ss question?

d. i assume the underlined word is "role." reformat if it isn't.

explanation:

role is closest to part because when replacing words, "playing a vital decision," "playing a vital activity," and "playing a vital dollar" don't make logical sense. the only meaningful choice is "playing a vital part."

this fits one of merriam-webster's definitions of role: "a function or part performed especially in a particular operation or process."
