Input: Read this: Given the wide range of styles in classical music, from Medieval plainchant sung by monks to Classical and Romantic symphonies for orchestra from the 1700s and 1800s to avant-garde atonal compositions for solo piano from the 1900s, it is difficult to list characteristics that can be attributed to all works of that type. However, there are characteristics that classical music contains that few or no other genres of music contain, such as the use of a printed score and the performance of very complex instrumental works (e.g., the fugue). As well, although the symphony did not exist through the entire classical music period, from the mid-1700s to the 2000s the symphony ensemble—and the works written for it—have become a defining feature of classical music.
Question: What did not exist through the entire classical music period?

Output: the symphony


QUES: However, the lifecycles of most living polychaetes, which are almost all marine animals, are unknown, and only about 25% of the 300+ species whose lifecycles are known follow this pattern. About 14% use a similar external fertilization but produce yolk-rich eggs, which reduce the time the larva needs to spend among the plankton, or eggs from which miniature adults emerge rather than larvae. The rest care for the fertilized eggs until they hatch – some by producing jelly-covered masses of eggs which they tend, some by attaching the eggs to their bodies and a few species by keeping the eggs within their bodies until they hatch. These species use a variety of methods for sperm transfer; for example, in some the females collect sperm released into the water, while in others the males have a penis that inject sperm into the female. There is no guarantee that this is a representative sample of polychaetes' reproductive patterns, and it simply reflects scientists' current knowledge.

How many species of polychaetes have known lifecycles?
What is the answer?
ANS: about 25%


QUES: Von Neumann entered government service (Manhattan Project) primarily because he felt that, if freedom and civilization were to survive, it would have to be because the US would triumph over totalitarianism from Nazism, Fascism and Soviet Communism. During a Senate committee hearing he described his political ideology as "violently anti-communist, and much more militaristic than the norm". He was quoted in 1950 remarking, "If you say why not bomb [the Soviets] tomorrow, I say, why not today? If you say today at five o'clock, I say why not one o'clock?"
What was the project that von Neumann first participated in government?

ANS: Manhattan Project


The religion's failure to report abuse allegations to authorities has also been criticized. The Watch Tower Society's policy is that elders inform authorities when required by law to do so, but otherwise leave that action up to the victim and his or her family. The Australian Royal Commission into Institutional Responses to Child Sexual Abuse found that of 1006 alleged perpetrators of child sexual abuse identified by the Jehovah's Witnesses within their organization since 1950, "not one was reported by the church to secular authorities." William Bowen, a former Jehovah's Witness elder who established the Silentlambs organization to assist sex abuse victims within the religion, has claimed Witness leaders discourage followers from reporting incidents of sexual misconduct to authorities, and other critics claim the organization is reluctant to alert authorities in order to protect its "crime-free" reputation. In court cases in the United Kingdom and the United States the Watch Tower Society has been found to have been negligent in its failure to protect children from known sex offenders within the congregation and the Society has settled other child abuse lawsuits out of court, reportedly paying as much as $780,000 to one plaintiff without admitting wrongdoing.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): How much does the Watch Tower Society pay to lawyers each year to represent them against child sexual abuse cases?
Ah, so.. unanswerable


Question: Capacitors may catastrophically fail when subjected to voltages or currents beyond their rating, or as they reach their normal end of life. Dielectric or metal interconnection failures may create arcing that vaporizes the dielectric fluid, resulting in case bulging, rupture, or even an explosion. Capacitors used in RF or sustained high-current applications can overheat, especially in the center of the capacitor rolls. Capacitors used within high-energy capacitor banks can violently explode when a short in one capacitor causes sudden dumping of energy stored in the rest of the bank into the failing unit. High voltage vacuum capacitors can generate soft X-rays even during normal operation. Proper containment, fusing, and preventive maintenance can help to minimize these hazards.
Try to answer this question if possible: What can happen to capacitors used in low energy capacitor banks?
Answer: unanswerable


Problem: Social predation offers the possibility of predators to kill creatures larger than those that members of the species could overpower singly. Lions, hyenas, wolves, dholes, African wild dogs, and piranhas can kill large herbivores that single animals of the same species usually don't dispatch. Social predation allows some animals to organize hunts of creatures that would easily escape a single predator; thus chimpanzees can prey upon colobus monkeys, and Harris's hawks can cut off all possible escapes for a doomed rabbit. Extreme specialization of roles is evident in some hunting that requires co-operation between predators of very different species: humans with the aid of falcons or dogs, or fishing with cormorants. Social predation is often very complex behavior, and not all social creatures (for example, domestic cats) perform it. Even without complex intelligence but instinct alone, some ant species can destroy much larger creatures.
What method does a rabbit use to evade a group of predators?
