Problem: Heian period:

Following Kammu's death in 806 and a succession struggle among his sons, two new offices were established in an effort to adjust the Taika-Taihō administrative structure. Through the new Emperor's Private Office, the emperor could issue administrative edicts more directly and with more self-assurance than before. The new Metropolitan Police Board replaced the largely ceremonial imperial guard units. While these two offices strengthened the emperor's position temporarily, soon they and other Chinese-style structures were bypassed in the developing state. In 838 the end of the imperial-sanctioned missions to Tang China, which had begun in 630, marked the effective end of Chinese influence. Tang China was in a state of decline, and Chinese Buddhists were severely persecuted, undermining Japanese respect for Chinese institutions. Japan began to turn inward.

Who's influence began to increase in 630?

A: unanswerable


Problem: The popularization of the Jewish chant may be found in the writings of the Jewish philosopher Philo, born 20 BCE. Weaving together Jewish and Greek thought, Philo promoted praise without instruments, and taught that "silent singing" (without even vocal chords) was better still. This view parted with the Jewish scriptures, where Israel offered praise with instruments by God's own command (2 Chronicles 29:25). The shofar is the only temple instrument still being used today in the synagogue, and it is only used from Rosh Chodesh Elul through the end of Yom Kippur. The shofar is used by itself, without any vocal accompaniment, and is limited to a very strictly defined set of sounds and specific places in the synagogue service.
What is the one instrument still in use today by the synagogue?

Answer: shofar


Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
Lawrence Houston, head counsel of the SSU, CIG, and, later CIA, was a principle draftsman of the National Security Act of 1947 which dissolved the NIA and the CIG, and established both the National Security Council and the Central Intelligence Agency. In 1949, Houston would help draft the Central Intelligence Agency Act, (Public law 81-110) which authorized the agency to use confidential fiscal and administrative procedures, and exempted it from most limitations on the use of Federal funds. It also exempted the CIA from having to disclose its "organization, functions, officials, titles, salaries, or numbers of personnel employed." It created the program "PL-110", to handle defectors and other "essential aliens" who fell outside normal immigration procedures.
What program handled "essential aliens" that did not fall under normal immigration policies?
A: PL-110


Context and question: Chickens raised intensively for their meat are known as "broilers". Breeds have been developed that can grow to an acceptable carcass size (2 kg (4.4 lb)) in six weeks or less. Broilers grow so fast, their legs cannot always support their weight and their hearts and respiratory systems may not be able to supply enough oxygen to their developing muscles. Mortality rates at 1% are much higher than for less-intensively reared laying birds which take 18 weeks to reach similar weights. Processing the birds is done automatically with conveyor-belt efficiency. They are hung by their feet, stunned, killed, bled, scalded, plucked, have their heads and feet removed, eviscerated, washed, chilled, drained, weighed, and packed, all within the course of little over two hours.
How do chickens like to spend their vacations?
Answer: unanswerable


Question: Many of the instruments used to perform medieval music still exist, but in different forms. Medieval instruments included the wood flute (which in the 21st century is made of metal), the recorder and plucked string instruments like the lute. As well, early versions of the organ, fiddle (or vielle), and trombone (called the sackbut) existed. Medieval instruments in Europe had most commonly been used singly, often self accompanied with a drone note, or occasionally in parts. From at least as early as the 13th century through the 15th century there was a division of instruments into haut (loud, shrill, outdoor instruments) and bas (quieter, more intimate instruments).
Is there an answer to this question: What was an early version of the trombone called? 

Answer: sackbut


Question: The Constitution does not explicitly indicate the pre-eminence of any particular branch of government. However, James Madison wrote in Federalist 51, regarding the ability of each branch to defend itself from actions by the others, that "it is not possible to give to each department an equal power of self-defense. In republican government, the legislative authority necessarily predominates."
Is there an answer to this question: Who wrote in the Constitution that legislative authority is predominate?

Answer:
unanswerable
