Problem: In 1966, Yale began discussions with its sister school Vassar College about merging to foster coeducation at the undergraduate level. Vassar, then all-female and part of the Seven Sisterselite higher education schools that historically served as sister institutions to the Ivy League when the Ivy League still only admitted mententatively accepted, but then declined the invitation. Both schools introduced coeducation independently in 1969. Amy Solomon was the first woman to register as a Yale undergraduate; she was also the first woman at Yale to join an undergraduate society, St. Anthony Hall. The undergraduate class of 1973 was the first class to have women starting from freshman year; at the time, all undergraduate women were housed in Vanderbilt Hall at the south end of Old Campus.[citation needed]

Problem: Immunology is strongly experimental in everyday practice but is also characterized by an ongoing theoretical attitude. Many theories have been suggested in immunology from the end of the nineteenth century up to the present time. The end of the 19th century and the beginning of the 20th century saw a battle between "cellular" and "humoral" theories of immunity. According to the cellular theory of immunity, represented in particular by Elie Metchnikoff, it was cells more precisely, phagocytes that were responsible for immune responses. In contrast, the humoral theory of immunity, held by Robert Koch and Emil von Behring, among others, stated that the active immune agents were soluble components (molecules) found in the organism's "humors" rather than its cells.
What are two opposing theories of early 20th century immunology?

Answer: "cellular" and "humoral"

Problem: As part of its education-related initiatives, the foundation has funded journalists, think tanks, lobbying organizations and governments. Millions of dollars of grants to news organizations have funded reporting on education and higher education, including more than $1.4 million to the Education Writers Association to fund training for journalists who cover education. While some critics have feared the foundation for directing the conversation on education or pushing its point of view through news coverage, the foundation has said it lists all its grants publicly and does not enforce any rules for content among its grantees, who have editorial independence. Union activists in Chicago have accused Gates Foundation grantee Teach Plus, which was founded by new teachers and advocates against seniority-based layoffs, of "astroturfing".
