Bro, if you were a source of light, would you be able to see shadows?

I think so.

Explanation:

Here's two examples which lead me to believe yes. One, when miners wear headgear with flashlights on it, they still see shadows like any other person. The only difference is that they can choose where the shadow is percieved to be by simply adjusting the light or the way they are standing. Similarly, I believe animals like fireflies would be able to as well. I am unsure of this, but based on logic, I would have to assume the answer is yes.

the answer is yes and no im sure you could see em from a distance but you would not be able to see your own shadow

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."

a is your answer hope this ! : )
