Input: Consider Input: Passage: Evolution of the adaptive immune system occurred in an ancestor of the jawed vertebrates. Many of the classical molecules of the adaptive immune system (e.g., immunoglobulins and T cell receptors) exist only in jawed vertebrates. However, a distinct lymphocyte-derived molecule has been discovered in primitive jawless vertebrates, such as the lamprey and hagfish. These animals possess a large array of molecules called Variable lymphocyte receptors (VLRs) that, like the antigen receptors of jawed vertebrates, are produced from only a small number (one or two) of genes. These molecules are believed to bind pathogenic antigens in a similar way to antibodies, and with the same degree of specificity. Question: What molecules of the adaptive immune system only exist in jawed vertebrates?

Output: immunoglobulins and T cell receptors

Input: Consider Input: Passage: In many parts of the United States, after the 1954 decision in the landmark court case Brown v. Board of Education of Topeka that demanded United States schools desegregate 'with all deliberate speed', local families organized a wave of private 'Christian academies'. In much of the U.S. South, many white students migrated to the academies, while public schools became in turn more heavily concentrated with African-American students (see List of private schools in Mississippi). The academic content of the academies was usually College Preparatory. Since the 1970s, many of these 'segregation academies' have shut down, although some continue to operate.[citation needed] Question: What was the primary race of students attending Christian academies after the Brown decision?
Output: white
