Problem: Most hunter-gatherers are nomadic or semi-nomadic and live in temporary settlements. Mobile communities typically construct shelters using impermanent building materials, or they may use natural rock shelters, where they are available.
What kind of natural structure do hunter-gatherers use?

Answer: rock shelters


Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
The Scheinergrade (Sch.) system was devised by the German astronomer Julius Scheiner (1858–1913) in 1894 originally as a method of comparing the speeds of plates used for astronomical photography. Scheiner's system rated the speed of a plate by the least exposure to produce a visible darkening upon development. Speed was expressed in degrees Scheiner, originally ranging from 1° Sch. to 20° Sch., where an increment of 19° Sch. corresponded to a hundredfold increase in sensitivity, which meant that an increment of 3° Sch. came close to a doubling of sensitivity.
What measured the visible darkening of a developing photograph?
A: unanswerable


Context and question: When an inductive circuit is opened, the current through the inductance collapses quickly, creating a large voltage across the open circuit of the switch or relay. If the inductance is large enough, the energy will generate a spark, causing the contact points to oxidize, deteriorate, or sometimes weld together, or destroying a solid-state switch. A snubber capacitor across the newly opened circuit creates a path for this impulse to bypass the contact points, thereby preserving their life; these were commonly found in contact breaker ignition systems, for instance. Similarly, in smaller scale circuits, the spark may not be enough to damage the switch but will still radiate undesirable radio frequency interference (RFI), which a filter capacitor absorbs. Snubber capacitors are usually employed with a low-value resistor in series, to dissipate energy and minimize RFI. Such resistor-capacitor combinations are available in a single package.
What type of capacitor is used to make a path to bypass the contact points?
Answer: A snubber capacitor


Question: Jehovah's Witnesses believe their religion is a restoration of first-century Christianity. Doctrines of Jehovah's Witnesses are established by the Governing Body, which assumes responsibility for interpreting and applying scripture. The Governing Body does not issue any single, comprehensive "statement of faith", but prefers to express its doctrinal position in a variety of ways through publications published by the Watch Tower Society. Their publications teach that doctrinal changes and refinements result from a process of progressive revelation, in which God gradually reveals his will and purpose, and that such enlightenment or "new light" results from the application of reason and study, the guidance of the holy spirit, and direction from Jesus Christ and angels. The Society also teaches that members of the Governing Body are helped by the holy spirit to discern "deep truths", which are then considered by the entire Governing Body before it makes doctrinal decisions. The religion's leadership, while disclaiming divine inspiration and infallibility, is said to provide "divine guidance" through its teachings described as "based on God's Word thus ... not from men, but from Jehovah."
Is there an answer to this question: What did first-century Christians call themselves?

Answer: unanswerable


Question: The word Ottoman is a historical anglicisation of the name of Osman I, the founder of the Empire and of the ruling House of Osman (also known as the Ottoman dynasty). Osman's name in turn was derived from the Persian form of the name ʿUthmān عثمان of ultimately Arabic origin. In Ottoman Turkish, the empire was referred to as Devlet-i ʿAliyye-yi ʿOsmâniyye (دَوْلَتِ عَلِيّهٔ عُثمَانِیّه), (literally "The Supreme State of the Ottomans") or alternatively Osmanlı Devleti (عثمانلى دولتى).[dn 5] In Modern Turkish, it is known as Osmanlı İmparatorluğu ("Ottoman Empire") or Osmanlı Devleti ("The Ottoman State").
Is there an answer to this question: What was another name for the Ottoman Dynasty? 

Answer:
House of Osman
