[Q]: Question: "When are discernible states the same thing?"  Context: "Arguing against the absolutist position, Leibniz offers a number of thought experiments with the purpose of showing that there is contradiction in assuming the existence of facts such as absolute location and velocity. These arguments trade heavily on two principles central to his philosophy: the principle of sufficient reason and the identity of indiscernibles. The principle of sufficient reason holds that for every fact, there is a reason that is sufficient to explain what and why it is the way it is and not otherwise. The identity of indiscernibles states that if there is no way of telling two entities apart, then they are one and the same thing."  Answer:
****
[A]: if there is no way of telling two entities apart


[Q]: Question: "What happened during the 37 year of the 1800s?"  Context: "In December 1831, he joined the Beagle expedition as a gentleman naturalist and geologist. He read Charles Lyell's Principles of Geology and from the first stop ashore, at St. Jago, found Lyell's uniformitarianism a key to the geological history of landscapes. Darwin discovered fossils resembling huge armadillos, and noted the geographical distribution of modern species in hope of finding their "centre of creation". The three Fuegian missionaries the expedition returned to Tierra del Fuego were friendly and civilised, yet to Darwin their relatives on the island seemed "miserable, degraded savages", and he no longer saw an unbridgeable gap between humans and animals. As the Beagle neared England in 1836, he noted that species might not be fixed."  Answer:

[Q]: Question: "What occurred in the 64th year of the 20th century?"  Context: "The long-awaited takeover of Universal Pictures by MCA, Inc. happened in mid-1962 as part of the MCA-Decca Records merger. The company reverted in name to Universal Pictures. As a final gesture before leaving the talent agency business, virtually every MCA client was signed to a Universal contract. In 1964 MCA formed Universal City Studios, Inc., merging the motion pictures and television arms of Universal Pictures Company and Revue Productions (officially renamed as Universal Television in 1966). And so, with MCA in charge, Universal became a full-blown, A-film movie studio, with leading actors and directors under contract; offering slick, commercial films; and a studio tour subsidiary launched in 1964. Television production made up much of the studio's output, with Universal heavily committed, in particular, to deals with NBC (which later merged with Universal to form NBC Universal; see below) providing up to half of all prime time shows for several seasons. An innovation during this period championed by Universal was the made-for-television movie."  Answer:
****

MCA formed Universal City Studios
