Read this line from the passage:
that, and thy repentance, may avail to take the scarlet letter of thy breast
which theme of the story does the scarlet letter symbolize?
a. suffering
b. murder
c. shame
d. sacrifice

So this is from previous knowledge of what a scarlet letter is
it is an equivalent to shame
if i said that my guitar playing is a scarlet letter id be saying that i am ashamed of my guitar playing.

hope this helps.

Ifound this on google “use commas to separate two or more coordinate adjectives that describe the same noun. be sure never to add an extra comma between the final adjective and the noun itself or to use commas with non-coordinate adjectives.” i hope this you for what your looking for
