Question: In the late 1960s, the term heavy metal was used interchangeably with hard rock, but gradually began to be used to describe music played with even more volume and intensity. While hard rock maintained a bluesy rock and roll identity, including some swing in the back beat and riffs that tended to outline chord progressions in their hooks, heavy metal's riffs often functioned as stand-alone melodies and had no swing in them. Heavy metal took on "darker" characteristics after Black Sabbath's breakthrough at the beginning of the 1970s. In the 1980s it developed a number of subgenres, often termed extreme metal, some of which were influenced by hardcore punk, and which further differentiated the two styles. Despite this differentiation, hard rock and heavy metal have existed side by side, with bands frequently standing on the boundary of, or crossing between, the genres.
Is there an answer to this question: What band had a 1960s break through with an emphasis on darker themes?

Answer: unanswerable


Question: The clearance of the pathogens, either treatment-induced or spontaneous, it can be influenced by the genetic variants carried by the individual patients. For instance, for genotype 1 hepatitis C treated with Pegylated interferon-alpha-2a or Pegylated interferon-alpha-2b (brand names Pegasys or PEG-Intron) combined with ribavirin, it has been shown that genetic polymorphisms near the human IL28B gene, encoding interferon lambda 3, are associated with significant differences in the treatment-induced clearance of the virus. This finding, originally reported in Nature, showed that genotype 1 hepatitis C patients carrying certain genetic variant alleles near the IL28B gene are more possibly to achieve sustained virological response after the treatment than others. Later report from Nature demonstrated that the same genetic variants are also associated with the natural clearance of the genotype 1 hepatitis C virus.
Is there an answer to this question: What is the brand name Pegasys for?

Answer: Pegylated interferon-alpha-2b


Question: These developments led to the theory of conservation of energy, formalized largely by William Thomson (Lord Kelvin) as the field of thermodynamics. Thermodynamics aided the rapid development of explanations of chemical processes by Rudolf Clausius, Josiah Willard Gibbs, and Walther Nernst. It also led to a mathematical formulation of the concept of entropy by Clausius and to the introduction of laws of radiant energy by Jožef Stefan. According to Noether's theorem, the conservation of energy is a consequence of the fact that the laws of physics do not change over time. Thus, since 1918, theorists have understood that the law of conservation of energy is the direct mathematical consequence of the translational symmetry of the quantity conjugate to energy, namely time.
Is there an answer to this question: Who developed the concept of the introduction of laws of radiant energy?

Answer: Jožef Stefan


Question: Hayek disapproved of the notion of 'social justice'. He compared the market to a game in which 'there is no point in calling the outcome just or unjust' and argued that 'social justice is an empty phrase with no determinable content'; likewise "the results of the individual's efforts are necessarily unpredictable, and the question as to whether the resulting distribution of incomes is just has no meaning". He generally regarded government redistribution of income or capital as an unacceptable intrusion upon individual freedom: "the principle of distributive justice, once introduced, would not be fulfilled until the whole of society was organized in accordance with it. This would produce a kind of society which in all essential respects would be the opposite of a free society."
Is there an answer to this question: What concept did Hayek dislike?

Answer:
social justice
