TASK DEFINITION: This task is about writing a correct answer for the reading comprehension task. Based on the information provided in a given passage, you should identify the shortest continuous text span from the passage that serves as an answer to the given question. Avoid answers that are incorrect or provides incomplete justification for the question.
PROBLEM: Passage: The softness of copper partly explains its high electrical conductivity (59.6×106 S/m) and thus also high thermal conductivity, which are the second highest (to silver) among pure metals at room temperature. This is because the resistivity to electron transport in metals at room temperature mostly originates from scattering of electrons on thermal vibrations of the lattice, which are relatively weak for a soft metal. The maximum permissible current density of copper in open air is approximately 3.1×106 A/m2 of cross-sectional area, above which it begins to heat excessively. As with other metals, if copper is placed against another metal, galvanic corrosion will occur. Question: What is the explanation for copper's capacity for electrical conductivity?

SOLUTION: The softness

PROBLEM: Passage: Hegel certainly intends to preserve what he takes to be true of German idealism, in particular Kant's insistence that ethical reason can and does go beyond finite inclinations. For Hegel there must be some identity of thought and being for the "subject" (any human observer)) to be able to know any observed "object" (any external entity, possibly even another human) at all. Under Hegel's concept of "subject-object identity," subject and object both have Spirit (Hegel's ersatz, redefined, nonsupernatural "God") as their conceptual (not metaphysical) inner reality—and in that sense are identical. But until Spirit's "self-realization" occurs and Spirit graduates from Spirit to Absolute Spirit status, subject (a human mind) mistakenly thinks every "object" it observes is something "alien," meaning something separate or apart from "subject." In Hegel's words, "The object is revealed to it [to "subject"] by [as] something alien, and it does not recognize itself." Self-realization occurs when Hegel (part of Spirit's nonsupernatural Mind, which is the collective mind of all humans) arrives on the scene and realizes that every "object" is himself, because both subject and object are essentially Spirit. When self-realization occurs and Spirit becomes Absolute Spirit, the "finite" (man, human) becomes the "infinite" ("God," divine), replacing the imaginary or "picture-thinking" supernatural God of theism: man becomes God. Tucker puts it this way: "Hegelianism . . . is a religion of self-worship whose fundamental theme is given in Hegel's image of the man who aspires to be God himself, who demands 'something more, namely infinity.'" The picture Hegel presents is "a picture of a self-glorifying humanity striving compulsively, and at the end successfully, to rise to divinity." Question: What does Hegel mean by "object"?

SOLUTION: any external entity

PROBLEM: Passage: Between 1945 and 1989, the share of ethnic Estonians in the population resident within the currently defined boundaries of Estonia dropped to 61%, caused primarily by the Soviet programme promoting mass immigration of urban industrial workers from Russia, Ukraine, and Belarus, as well as by wartime emigration and Joseph Stalin's mass deportations and executions.[citation needed] By 1989, minorities constituted more than one-third of the population, as the number of non-Estonians had grown almost fivefold. Question: What year did minorities in Estonia make up more than a third of the country?

SOLUTION:
1989
