Problem: Wayback Machine:

There are technical limitations to archiving a web site, and as a consequence, it is possible for opposing parties in litigation to misuse the results provided by web site archives. This problem can be exacerbated by the practice of submitting screen shots of web pages in complaints, answers, or expert witness reports, when the underlying links are not exposed and therefore, can contain errors. For example, archives such as the Wayback Machine do not fill out forms and therefore, do not include the contents of non-RESTful e-commerce databases in their archives.

What kind of limitations exist in keeping copies of a website?

A: technical

Problem: In 1795, the Prussian linguist and philosopher Wilhelm von Humboldt (17671835) called for an anthropology that would synthesize Kant's and Herder's interests. During the Romantic era, scholars in Germany, especially those concerned with nationalist movementssuch as the nationalist struggle to create a "Germany" out of diverse principalities, and the nationalist struggles by ethnic minorities against the Austro-Hungarian Empiredeveloped a more inclusive notion of culture as "worldview" (Weltanschauung). According to this school of thought, each ethnic group has a distinct worldview that is incommensurable with the worldviews of other groups. Although more inclusive than earlier views, this approach to culture still allowed for distinctions between "civilized" and "primitive" or "tribal" cultures.
Which era did scholars of Germany develop a less inclusive culture?

Context and question: In his work "On the Jews and Their Lies" (1543), German Reformation leader Martin Luther claims that Jewish history was "assailed by much heresy", and that Christ the logos swept away the Jewish heresy and goes on to do so, "as it still does daily before our eyes." He stigmatizes Jewish Prayer as being "blasphemous" (sic) and a lie, and vilifies Jews in general as being spiritually "blind" and "surely possessed by all devils." Luther calls the members of the Orthodox Catholic Church "papists" and heretics, and has a special spiritual problem with Jewish circumcision.
What is said to be a special spiritual problem?
Answer: Jewish circumcision

Question: An advantage of the universal motor is that AC supplies may be used on motors which have some characteristics more common in DC motors, specifically high starting torque and very compact design if high running speeds are used. The negative aspect is the maintenance and short life problems caused by the commutator. Such motors are used in devices such as food mixers and power tools which are used only intermittently, and often have high starting-torque demands. Multiple taps on the field coil provide (imprecise) stepped speed control. Household blenders that advertise many speeds frequently combine a field coil with several taps and a diode that can be inserted in series with the motor (causing the motor to run on half-wave rectified AC). Universal motors also lend themselves to electronic speed control and, as such, are an ideal choice for devices like domestic washing machines. The motor can be used to agitate the drum (both forwards and in reverse) by switching the field winding with respect to the armature.
Is there an answer to this question: How is stepped speed control achieved?

Answer: Multiple taps on the field coil provide

Question: The modern Standard Chinese exonym for the ethnic Tibetan region is Zangqu (Chinese: ; pinyin: Zangqu), which derives by metonymy from the Tsang region around Shigatse plus the addition of a Chinese suffix, qu, which means "area, district, region, ward". Tibetan people, language, and culture, regardless of where they are from, are referred to as Zang (Chinese: ; pinyin: Zang) although the geographical term Xizang is often limited to the Tibet Autonomous Region. The term Xizang was coined during the Qing dynasty in the reign of the Jiaqing Emperor (17961820) through the addition of a prefix meaning "west" ( xi) to Zang.
Is there an answer to this question: What is the Tsang exonym for the ethnic Tibetan region?

Answer:
unanswerable
