Problem: Question: "Which isotope appears first in the decay sequence, uranium-237 or uranium-233?" Context: "Natural uranium consists of three major isotopes: uranium-238 (99.28% natural abundance), uranium-235 (0.71%), and uranium-234 (0.0054%). All three are radioactive, emitting alpha particles, with the exception that all three of these isotopes have small probabilities of undergoing spontaneous fission, rather than alpha emission. There are also five other trace isotopes: uranium-239, which is formed when 238U undergoes spontaneous fission, releasing neutrons that are captured by another 238U atom; uranium-237, which is formed when 238U captures a neutron but emits two more, which then decays to neptunium-237; uranium-233, which is formed in the decay chain of that neptunium-237; and finally, uranium-236 and -240, which appear in the decay chain of primordial plutonium-244. It is also expected that thorium-232 should be able to undergo double beta decay, which would produce uranium-232, but this has not yet been observed experimentally." Answer:

A: uranium-237

Problem: Question: "What kind of rule is there to keep from child working?" Context: "Some scholars[who?] suggest any labour by children aged 18 years or less is wrong since this encourages illiteracy, inhumane work and lower investment in human capital. Child labour, claim these activists, also leads to poor labour standards for adults, depresses the wages of adults in developing countries as well as the developed countries, and dooms the third world economies to low-skill jobs only capable of producing poor quality cheap exports. More children that work in poor countries, the fewer and worse-paid are the jobs for adults in these countries. In other words, there are moral and economic reasons that justify a blanket ban on labour from children aged 18 years or less, everywhere in the world." Answer:

A: a blanket ban on labour from children aged 18 years or less

Problem: Question: "Universal Television did not exist in what year?" 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:

A:
1962
