In this task, you are given a question and a context passage. You have to answer the question based on the given passage.

Einstein created a way of thinking called a?, Context: It was only the orbit of the planet Mercury that Newton's Law of Gravitation seemed not to fully explain. Some astrophysicists predicted the existence of another planet (Vulcan) that would explain the discrepancies; however, despite some early indications, no such planet could be found. When Albert Einstein formulated his theory of general relativity (GR) he turned his attention to the problem of Mercury's orbit and found that his theory added a correction, which could account for the discrepancy. This was the first time that Newton's Theory of Gravity had been shown to be less correct than an alternative.

What creature could be found besides two sea lions?, Context: "Azure, three ships with three masts, rigged and under full sail, the sails, pennants and ensigns Argent, each charged with a cross Gules; on a chief of the second a pale quarterly Azure and Gules, on the 1st and 4th a fleur-de-lis or, on the 2nd and 3rd a leopard or, between two roses Gules seeded Or barbed Vert." The shield had as a crest: "A sphere without a frame, bounded with the Zodiac in bend Or, between two pennants flottant Argent, each charged with a cross Gules, over the sphere the words DEUS INDICAT" (Latin: God Indicates). The supporters were two sea lions (lions with fishes' tails) and the motto was DEO DUCENTE NIL NOCET (Latin: Where God Leads, Nothing Hurts).

Which major isotope of uranium is the most common?, 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.
