PROBLEM: Sarvastivada teachings—which were criticized by Nāgārjuna—were reformulated by scholars such as Vasubandhu and Asanga and were adapted into the Yogacara school. While the Mādhyamaka school held that asserting the existence or non-existence of any ultimately real thing was inappropriate, some exponents of Yogacara asserted that the mind and only the mind is ultimately real (a doctrine known as cittamatra). Not all Yogacarins asserted that mind was truly existent; Vasubandhu and Asanga in particular did not.[web 11] These two schools of thought, in opposition or synthesis, form the basis of subsequent Mahayana metaphysics in the Indo-Tibetan tradition.

SOLUTION: What teaching were criticized by Nagarjuna?

PROBLEM: Following the end of World War II the educational gap between White and Black Americans was widened by Dwight D. Eisenhower's GI Bill. This piece of legislation paved the way for white GIs to attend college. Despite their veteran status returning black servicemen were not afforded loans at the same rate as whites. Furthermore, at the time of its introduction, segregation was still the law of the land barring blacks from the best institutions. Overall, "Nearly 8 million servicemen and servicewomen were educated under the provisions of the GI Bill after World War II. But for blacks, higher educational opportunities were so few that the promise of the GI Bill went largely unfulfilled."

SOLUTION: What major event preceded the growth of the divide in education between White and Black Americans?
