Thurgood Marshall's litigation of Brown v. Board of Education in 1952—the landmark case, decided in 1954, that made segregation illegal in United States public schools—was not his first case before the U.S. Supreme Court. ████ █████ ████████ █████ ████ ███ █████ ██ █████████ ██ ███ █████ ██ ███ ███████ █████ ██████ ███ ██████████ ████████ ███ █████████████ ██ ██████ ███████ ████ █████████ ███████████ ██ ████ █████ ███████████ █████ ██ █████ ██████████ ███ █████ ████████ ██ ███ ███████████ ██ ██████████████ ███████ ███████ █████████ ████ █████ ███ ███ ███ ███████ ██ ██████

sharpen the distinction ████ ██ ███ ██████ █████████
The purpose of P3 isn’t to clarify or sharpen the distinction between the less theoretical and more theoretical approaches described in P2. Although P3 does involve a discussion of cases involving both approaches, the reason the author discusses these cases is to show how Marshall’s strategy actually worked out in practice. P2 discusses his strategy, and P3 discusses the resutls. The author isn’t trying to help us understand the difference between the less/more theoretical approaches in P3.
question the claim ████ ██ ███ █████ █████████
P3 doesn’t question any claim in P1. Rather, it supports the scholars claim in P1.
summarize the argument ████ ██ ███ █████ ███ ██████████
P3 discusses new material — how Marshall’s strategy worked out in practice. It doesn’t merely recap what’s said in P1 and P2.
counter the criticism ██ █████████ ███ ██████ ████ ██ ███ ██████ █████████
P3 doesn’t counter criticism of “separate but equal.” It tells us the cases Marshall worked on that led up to his successful overturning of “separate but equal.”
