Problem: Han dynasty:

Han-era medical physicians believed that the human body was subject to the same forces of nature that governed the greater universe, namely the cosmological cycles of yin and yang and the five phases. Each organ of the body was associated with a particular phase. Illness was viewed as a sign that qi or "vital energy" channels leading to a certain organ had been disrupted. Thus, Han-era physicians prescribed medicine that was believed to counteract this imbalance. For example, since the wood phase was believed to promote the fire phase, medicinal ingredients associated with the wood phase could be used to heal an organ associated with the fire phase. To this end, the physician Zhang Zhongjing (c. 150c. 219 AD) prescribed regulated diets rich in certain foods that were thought to cure specific illnesses. These are now known to be nutrition disorders caused by the lack of certain vitamins consumed in one's diet. Besides dieting, Han physicians also prescribed moxibustion, acupuncture, and calisthenics as methods of maintaining one's health. When surgery was performed by the physician Hua Tuo (d. 208 AD), he used anesthesia to numb his patients' pain and prescribed a rubbing ointment that allegedly sped the process of healing surgical wounds.

Who believed that the same forces that controlled the universe also controlled the human body?

A: Han-era medical physicians

Problem: A sociological comparative study by the Pew Research Center found that Jehovah's Witnesses in the United States ranked highest in statistics for getting no further than high school graduation, belief in God, importance of religion in one's life, frequency of religious attendance, frequency of prayers, frequency of Bible reading outside of religious services, belief their prayers are answered, belief that their religion can only be interpreted one way, belief that theirs is the only one true faith leading to eternal life, opposition to abortion, and opposition to homosexuality. In the study, Jehovah's Witnesses ranked lowest in statistics for having earned a graduate degree and interest in politics.
What do few Jehovah's Witnesses earn?

Answer: a graduate degree

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
The initial prototype shown in May 2005 featured two HDMI ports, three Ethernet ports and six USB ports; however, when the system was shown again a year later at E3 2006, these were reduced to one HDMI port, one Ethernet port and four USB ports, presumably to cut costs. Two hardware configurations were also announced for the console: a 20 GB model and a 60 GB model, priced at US$499 (499) and US$599 (599), respectively. The 60 GB model was to be the only configuration to feature an HDMI port, Wi-Fi internet, flash card readers and a chrome trim with the logo in silver. Both models were announced for a simultaneous worldwide release: November 11, 2006, for Japan and November 17, 2006, for North America and Europe.
In addition to the 20 GB model, what larger model did Sony offer?
A: 60 GB

Context and question: A servo system differs from some stepper motor applications in that the position feedback is continuous while the motor is running; a stepper system relies on the motor not to "miss steps" for short term accuracy, although a stepper system may include a "home" switch or other element to provide long-term stability of control. For instance, when a typical dot matrix computer printer starts up, its controller makes the print head stepper motor drive to its left-hand limit, where a position sensor defines home position and stops stepping. As long as power is on, a bidirectional counter in the printer's microprocessor keeps track of print-head position.
How are servo motors the same as stepper motors?
Answer: unanswerable

Question: Differences in feasts may also originate from doctrinal issuesthe Feast of the Assumption is such an example. Given that there is no agreement among all Christians on the circumstances of the death, Dormition or Assumption of Mary, the feast of assumption is celebrated among some denominations and not others. While the Catholic Church celebrates the Feast of the Assumption on August 15, some Eastern Catholics celebrate it as Dormition of the Theotokos, and may do so on August 28, if they follow the Julian calendar. The Eastern Orthodox also celebrate it as the Dormition of the Theotokos, one of their 12 Great Feasts. Protestants do not celebrate this, or any other Marian feasts.
Is there an answer to this question: On what date of the Julian calendar do Eastern Catholics celebrate the Domition of the Theotokos?

Answer: August 28

Birds are often important to island ecology. Birds have frequently reached islands that mammals have not; on those islands, birds may fulfill ecological roles typically played by larger animals. For example, in New Zealand the moas were important browsers, as are the kereru and kokako today. Today the plants of New Zealand retain the defensive adaptations evolved to protect them from the extinct moa. Nesting seabirds may also affect the ecology of islands and surrounding seas, principally through the concentration of large quantities of guano, which may enrich the local soil and the surrounding seas.
In New Zealand, what were important browsers, as the kereru and kokako are today?
A:
moas
