This question is typical of a Part B on the U.S. Government and Politics FRQ #3 — Supreme Court Comparison question. On the AP exam, students often fail to receive a point for this question because they have not referenced the facts of the required case (the one in the curriculum that you are to have knowledge of, in this case Shaw v Reno) in comparison with the summary of the case that is provided in the question.
To assure that you receive the point, I recommend this format:
Sentence # 1: Fact in the required case (Shaw v. Reno) that relates to the given case.
Sentence #2: Explain how the facts of the given case are similar to the required case (this information comes from the summary of the case provided in the question.)
Sentence # 3: How the court followed precedent and a similar interpretation of the 14th amendment equal protection clause in Shaw v Reno to reach a similar decision in Bush v. Vera.
