Input: Read this: Studies of nutritional status must take into account the state of the body before and after experiments, as well as the chemical composition of the whole diet and of all material excreted and eliminated from the body (in urine and feces). Comparing the food to the waste can help determine the specific compounds and elements absorbed and metabolized in the body. The effects of nutrients may only be discernible over an extended period, during which all food and waste must be analyzed. The number of variables involved in such experiments is high, making nutritional studies time-consuming and expensive, which explains why the science of animal nutrition is still slowly evolving.
Question: What needs to be compared to the waste products from humans to determine what is absorbed in the body?

Output: food


QUES: Stephen Hawking in particular has addressed a connection between time and the Big Bang. In A Brief History of Time and elsewhere, Hawking says that even if time did not begin with the Big Bang and there were another time frame before the Big Bang, no information from events then would be accessible to us, and nothing that happened then would have any effect upon the present time-frame. Upon occasion, Hawking has stated that time actually began with the Big Bang, and that questions about what happened before the Big Bang are meaningless. This less-nuanced, but commonly repeated formulation has received criticisms from philosophers such as Aristotelian philosopher Mortimer J. Adler.

What does Adler believe that questions about what happened before the Big Bang are?
What is the answer?
ANS: unanswerable

Meanwhile, U.S. garrisons in Japan continually dispatched soldiers and matériel to reinforce defenders in the Pusan Perimeter. Tank battalions deployed to Korea directly from the U.S. mainland from the port of San Francisco to the port of Pusan, the largest Korean port. By late August, the Pusan Perimeter had some 500 medium tanks battle-ready. In early September 1950, ROK Army and UN Command forces outnumbered the KPA 180,000 to 100,000 soldiers. The UN forces, once prepared, counterattacked and broke out of the Pusan Perimeter.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): Where in the United States was the tank battalion located?
Ah, so.. San Francisco


Question: In the 19th century, musical institutions emerged from the control of wealthy patrons, as composers and musicians could construct lives independent of the nobility. Increasing interest in music by the growing middle classes throughout western Europe spurred the creation of organizations for the teaching, performance, and preservation of music. The piano, which achieved its modern construction in this era (in part due to industrial advances in metallurgy) became widely popular with the middle class, whose demands for the instrument spurred a large number of piano builders. Many symphony orchestras date their founding to this era. Some musicians and composers were the stars of the day; some, like Franz Liszt and Niccolò Paganini, fulfilled both roles.
Try to answer this question if possible: What class increased it's interest in music during the 19th century?
Answer: middle classes
