([2020 Prentice Hall Brief Review] United States History and Government) 1. What words are evidence that the northwest ordinance is a turning point in history?
2. Why are the years 1781-1789 under the Articles of Confederation called the "Critical Period"?

my good sir, your answer here is "jvhrwekjhvbebebjb"

your welcome.

a factory opens that mass-produces light bulbs.

explanation:

not sure if that's an answer to your questions but this is an example! : )

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."
