Input: Article: New chemical glass compositions or new treatment techniques can be initially investigated in small-scale laboratory experiments. The raw materials for laboratory-scale glass melts are often different from those used in mass production because the cost factor has a low priority. In the laboratory mostly pure chemicals are used. Care must be taken that the raw materials have not reacted with moisture or other chemicals in the environment (such as alkali or alkaline earth metal oxides and hydroxides, or boron oxide), or that the impurities are quantified (loss on ignition). Evaporation losses during glass melting should be considered during the selection of the raw materials, e.g., sodium selenite may be preferred over easily evaporating SeO2. Also, more readily reacting raw materials may be preferred over relatively inert ones, such as Al(OH)3 over Al2O3. Usually, the melts are carried out in platinum crucibles to reduce contamination from the crucible material. Glass homogeneity is achieved by homogenizing the raw materials mixture (glass batch), by stirring the melt, and by crushing and re-melting the first melt. The obtained glass is usually annealed to prevent breakage during processing.

Now answer this question: What material is useful in glassmaking because of its slow evaporation?

Output: sodium selenite


Article: American sociology in the 1940s and 1950s was dominated largely by Talcott Parsons, who argued that aspects of society that promoted structural integration were therefore "functional". This structural functionalism approach was questioned in the 1960s, when sociologists came to see this approach as merely a justification for inequalities present in the status quo. In reaction, conflict theory was developed, which was based in part on the philosophies of Karl Marx. Conflict theorists saw society as an arena in which different groups compete for control over resources. Symbolic interactionism also came to be regarded as central to sociological thinking. Erving Goffman saw social interactions as a stage performance, with individuals preparing "backstage" and attempting to control their audience through impression management. While these theories are currently prominent in sociological thought, other approaches exist, including feminist theory, post-structuralism, rational choice theory, and postmodernism.

Question: What is the main belief of conflict theory?
Ans: different groups compete for control over resources


Here is a question about this article: The predominant religions in Zhejiang are Chinese folk religions, Taoist traditions and Chinese Buddhism. According to surveys conducted in 2007 and 2009, 23.02% of the population believes and is involved in cults of ancestors, while 2.62% of the population identifies as Christian, decreasing from 3.92% in 2004. The reports didn't give figures for other types of religion; 74.36% of the population may be either irreligious or involved in worship of nature deities, Buddhism, Confucianism, Taoism, folk religious sects, and small minorities of Muslims.
What is the answer to this question: According to surveys in 2007 and 2009, what percent of the population believes in cults of ancestors?
****
So... 23.02%


The problem: Answer a question about this article:
The design architecture of USB is asymmetrical in its topology, consisting of a host, a multitude of downstream USB ports, and multiple peripheral devices connected in a tiered-star topology. Additional USB hubs may be included in the tiers, allowing branching into a tree structure with up to five tier levels. A USB host may implement multiple host controllers and each host controller may provide one or more USB ports. Up to 127 devices, including hub devices if present, may be connected to a single host controller. USB devices are linked in series through hubs. One hub—built into the host controller—is the root hub.
What HUB is built into the host controller?
****
The answer: the root hub


Problem: Please answer a question about the following article about John von Neumann:
Von Neumann introduced the study of rings of operators, through the von Neumann algebras. A von Neumann algebra is a *-algebra of bounded operators on a Hilbert space that is closed in the weak operator topology and contains the identity operator. The von Neumann bicommutant theorem shows that the analytic definition is equivalent to a purely algebraic definition as an algebra of symmetries. The direct integral was introduced in 1949 by John von Neumann. One of von Neumann's analyses was to reduce the classification of von Neumann algebras on separable Hilbert spaces to the classification of factors.
What does the von Neumann bicommutant theorem show?
A: the analytic definition is equivalent to a purely algebraic definition as an algebra of symmetries.

The history of Indian Buddhism may be divided into five periods: Early Buddhism (occasionally called Pre-sectarian Buddhism), Nikaya Buddhism or Sectarian Buddhism: The period of the Early Buddhist schools, Early Mahayana Buddhism, Later Mahayana Buddhism, and Esoteric Buddhism (also called Vajrayana Buddhism).

What is Esoteric Buddhism also called?
Answer:
Vajrayana
