How is the use of symbols related to culture?

Symbols mean something and show what you stand for and against so different cultures can show what their for and against by using symbols related to what ever they stand for or don't.

Explanation:

The use of symbols is the very basis of human culture. It is through symbols that we create our culture and communicate it to group members and future generations. Although specific examples vary from culture to culture, all cultures communicate symbolically.

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."
