In the poem "Barbara Frietchie," what happened before Barbara Frietchie "took up" the flag?

I can see that there are no choices.

Before Barbara "took up the flag," she "rose up."

She was pretty old and her age can be describe by mentioning "fourscore years and ten." This means she's about 90 years old and her posture is "bowing" due to her age.

Explanation:

It describes how Barbara took up the Union flag, which insulted the Confederate troops because they actually pulled it down earlier. Barbara was a member of the labor union during the Civil War. She became popular as a heroine in Whittier's poem. Her reputation has been promoted for generations that she's even the reason why tourists visit the city of Frederick, Maryland.

Hope this helpsʕ•ᴥ•ʔ
