Answer:
A text box in Chapter 9. It describes the structure and voting process justices use for rulings.
Explanation:
Chapter 9 is all about the Supreme Court, this means that the option with "Chapter 7" is not very accurate. We can eliminate that option. Then, the opinions saying "illustration of.." are not accurate because illustrations do not help you learn more about the job of a Supreme Court justice. This leaves the answer for Part A as the text box option. Now for Part B, if you look at the text box in Chapter 9, it talks about what the justices do for rulings. Hope this helps!
