Problem: Antibiotics:

With advances in medicinal chemistry, most modern antibacterials are semisynthetic modifications of various natural compounds. These include, for example, the beta-lactam antibiotics, which include the penicillins (produced by fungi in the genus Penicillium), the cephalosporins, and the carbapenems. Compounds that are still isolated from living organisms are the aminoglycosides, whereas other antibacterials—for example, the sulfonamides, the quinolones, and the oxazolidinones—are produced solely by chemical synthesis. Many antibacterial compounds are relatively small molecules with a molecular weight of less than 2000 atomic mass units.[citation needed]

What is the molecular weight loss of chemical synthesis?

A: unanswerable


Problem: Originally, the hardware architecture was so closely tied to the Mac OS operating system that it was impossible to boot an alternative operating system. The most common workaround, is to boot into Mac OS and then to hand over control to a Mac OS-based bootloader application. Used even by Apple for A/UX and MkLinux, this technique is no longer necessary since the introduction of Open Firmware-based PCI Macs, though it was formerly used for convenience on many Old World ROM systems due to bugs in the firmware implementation.[citation needed] Now, Mac hardware boots directly from Open Firmware in most PowerPC-based Macs or EFI in all Intel-based Macs.
What was introduced that made using Mac OS alternative operating systems easier?
---
Answer: Open Firmware-based PCI Macs


Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
In the mid-1950s, Frank Burnet, inspired by a suggestion made by Niels Jerne, formulated the clonal selection theory (CST) of immunity. On the basis of CST, Burnet developed a theory of how an immune response is triggered according to the self/nonself distinction: "self" constituents (constituents of the body) do not trigger destructive immune responses, while "nonself" entities (e.g., pathogens, an allograft) trigger a destructive immune response. The theory was later modified to reflect new discoveries regarding histocompatibility or the complex "two-signal" activation of T cells. The self/nonself theory of immunity and the self/nonself vocabulary have been criticized, but remain very influential.
What medical scientist first proposed the clonal selection theory of immunology?
A: Frank Burnet


Context and question: The plains at the foot of the Sierra Madre Occidental is an elongated mesa known as Altiplanicie Mexicana that exhibits a steppe climate and serves as a transition zone from the mountain climate in the western part of the state to the desert climate in the eastern side of the state. The steppe zone accounts for a third of the state's area, and it experiences pronounced dry and wet seasons. The pronounced rainy season in the steppe is usually observed in the months of July, August, and September. The steppe also encounters extreme temperatures that often reach over 100 °F in the summer and drop below 32 °F in the winter. The steppe zone is an important agriculture zone due to an extensive development of canals exploiting several rivers that flow down from the mountains. The steppe zone is the most populated area of the state.
The steppe reaches temperatures above what in the winter?
Answer: 100 °F


Question: The politics of Zhejiang is structured in a dual party-government system like all other governing institutions in Mainland China. The Governor of Zhejiang is the highest-ranking official in the People's Government of Zhejiang. However, in the province's dual party-government governing system, the Governor is subordinate to the Zhejiang Communist Party of China (CPC) Provincial Committee Secretary, colloquially termed the "Zhejiang CPC Party Chief".
Is there an answer to this question:  Who is the Governor not subordinate to?

Answer: unanswerable


In time, some ideas from these experiments and paradigm challenges may be adopted as the norm in education, just as Friedrich Fröbel's approach to early childhood education in 19th-century Germany has been incorporated into contemporary kindergarten classrooms. Other influential writers and thinkers have included the Swiss humanitarian Johann Heinrich Pestalozzi; the American transcendentalists Amos Bronson Alcott, Ralph Waldo Emerson, and Henry David Thoreau; the founders of progressive education, John Dewey and Francis Parker; and educational pioneers such as Maria Montessori and Rudolf Steiner, and more recently John Caldwell Holt, Paul Goodman, Frederick Mayer, George Dennison and Ivan Illich.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): Who from Switzerland was an influential in education?
Ah, so..
Johann Heinrich Pestalozzi
