Problem: A team led by Enrico Fermi in 1934 observed that bombarding uranium with neutrons produces the emission of beta rays (electrons or positrons from the elements produced; see beta particle). The fission products were at first mistaken for new elements of atomic numbers 93 and 94, which the Dean of the Faculty of Rome, Orso Mario Corbino, christened ausonium and hesperium, respectively. The experiments leading to the discovery of uranium's ability to fission (break apart) into lighter elements and release binding energy were conducted by Otto Hahn and Fritz Strassmann in Hahn's laboratory in Berlin. Lise Meitner and her nephew, the physicist Otto Robert Frisch, published the physical explanation in February 1939 and named the process "nuclear fission". Soon after, Fermi hypothesized that the fission of uranium might release enough neutrons to sustain a fission reaction. Confirmation of this hypothesis came in 1939, and later work found that on average about 2.5 neutrons are released by each fission of the rare uranium isotope uranium-235. Further work found that the far more common uranium-238 isotope can be transmuted into plutonium, which, like uranium-235, is also fissile by thermal neutrons. These discoveries led numerous countries to begin working on the development of nuclear weapons and nuclear power.
When was it observed that bombarding uranium with neutrons results in beta ray emission?
The answer is the following: 1934

Problem: In December 2015, West released a song titled "Facts". He announced in January 2016 on Twitter that SWISH would be released on February 11, after releasing new song "Real Friends" and a snippet of "No More Parties in L.A." with Kendrick Lamar. This also revived the GOOD Fridays initiative in which Kanye releases new singles every Friday. On January 26, 2016, West revealed he had renamed the album from SWISH to Waves, and also announced the premier of his Yeezy Season 3 clothing line at Madison Square Garden. In early 2016, several weeks prior to the release of his new album, West became embroiled in a short-lived social media altercation with rapper Wiz Khalifa on Twitter that eventually involved their mutual ex-partner, Amber Rose, who protested to West's mention of her and Khalifa's child. The feud involved allegations by Rose concerning her sexual relationship with West, and received significant media attention. As of February 2, 2016, West and Khalifa had reconciled. Several days ahead of the album's release, West again changed the title, this time to The Life of Pablo. On February 11, West premiered the album at Madison Square Garden as part of the presentation of his Yeezy Season 3 clothing line. Following the preview, West announced that he would be modifying the track list once more before its release to the public, and further delayed its release to finalize the recording of the track "Waves" at the behest of co-writer Chance the Rapper. He released the album exclusively on Tidal on 14 February 2016 following a performance on SNL.
What song by West was debuted in December 2015?
The answer is the following: "Facts"

Problem: After two forays into more serious dramatic films, Spielberg then directed the third Indiana Jones film, 1989's Indiana Jones and the Last Crusade. Once again teaming up with Lucas and Ford, Spielberg also cast actor Sean Connery in a supporting role as Indy's father. The film earned generally positive reviews and was another box office success, becoming the highest grossing film worldwide that year; its total box office receipts even topped those of Tim Burton's much-anticipated film Batman, which had been the bigger hit domestically. Also in 1989, he re-united with actor Richard Dreyfuss for the romantic comedy-drama Always, about a daredevil pilot who extinguishes forest fires. Spielberg's first romantic film, Always was only a moderate success and had mixed reviews.
Who played Indiana Jones's father?
The answer is the following: Sean Connery

Problem: Article 10 of the Berne Convention mandates that national laws provide for limitations to copyright, so that copyright protection does not extend to certain kinds of uses that fall under what the treaty calls "fair practice," including but not limited to minimal quotations used in journalism and education. The laws implementing these limitations and exceptions for uses that would otherwise be infringing broadly fall into the categories of either fair use or fair dealing. In common law systems, these fair practice statutes typically enshrine principles underlying many earlier judicial precedents, and are considered essential to freedom of speech.
What do these statutes represent?
The answer is the following:
principles underlying many earlier judicial precedents
