Here is a question about this article: The Rev. John J. Cavanaugh, C.S.C. served as president from 1946 to 1952. Cavanaugh's legacy at Notre Dame in the post-war years was devoted to raising academic standards and reshaping the university administration to suit it to an enlarged educational mission and an expanded student body and stressing advanced studies and research at a time when Notre Dame quadrupled in student census, undergraduate enrollment increased by more than half, and graduate student enrollment grew fivefold. Cavanaugh also established the Lobund Institute for Animal Studies and Notre Dame's Medieval Institute. Cavanaugh also presided over the construction of the Nieuwland Science Hall, Fisher Hall, and the Morris Inn, as well as the Hall of Liberal Arts (now O'Shaughnessy Hall), made possible by a donation from I.A. O'Shaughnessy, at the time the largest ever made to an American Catholic university. Cavanaugh also established a system of advisory councils at the university, which continue today and are vital to the university's governance and development
What is the answer to this question: What is O'Shaughnessy Hall of Notre Dame formerly known as?
****
So... Hall of Liberal Arts


Here is a question about this article: Salts of many oxidation states of uranium are water-soluble and may be studied in aqueous solutions. The most common ionic forms are U3+ (brown-red), U4+ (green), UO+
2 (unstable), and UO2+
2 (yellow), for U(III), U(IV), U(V), and U(VI), respectively. A few solid and semi-metallic compounds such as UO and US exist for the formal oxidation state uranium(II), but no simple ions are known to exist in solution for that state. Ions of U3+ liberate hydrogen from water and are therefore considered to be highly unstable. The UO2+
2 ion represents the uranium(VI) state and is known to form compounds such as uranyl carbonate, uranyl chloride and uranyl sulfate. UO2+
2 also forms complexes with various organic chelating agents, the most commonly encountered of which is uranyl acetate.
What is the answer to this question: What is the color of U4+?
****
So... green


Here is a question about this article: Residents of Oklahoma City suffered substantial losses on April 19, 1995 when Timothy McVeigh detonated a bomb in front of the Murrah building. The building was destroyed (the remnants of which had to be imploded in a controlled demolition later that year), more than 100 nearby buildings suffered severe damage, and 168 people were killed. The site has been commemorated as the Oklahoma City National Memorial and Museum. Since its opening in 2000, over three million people have visited. Every year on April 19, survivors, families and friends return to the memorial to read the names of each person lost.
What is the answer to this question: What year did the memorial first opened?

So...
2000
