Closed circuit television (cctv) surveillance cameras and improved street lighting are mechanical forms of a. crime discouragers b. crime inhibitors c. crime monitors d. crime obstructors

The correct answer is A, crime discourages.

Explanation:

A place surrounded by surveillance cameras is less likely to be the target of a crime, for they record all activity in that area, facilitating the identification of criminals. When streets have better lighting they become safer, because they provide visibility, which makes the happening of crime without witnesses more difficult. Both these measures are taken to discourage crime, but they don't necessarily prevent it.

fir trees are found in areas with cooler climates. fir trees have needles for leaves and remain green year-round.

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."
