Input: Read this: Rapid environmental changes typically cause mass extinctions. More than 99 percent of all species, amounting to over five billion species, that ever lived on Earth are estimated to be extinct. Estimates on the number of Earth's current species range from 10 million to 14 million, of which about 1.2 million have been documented and over 86 percent have not yet been described. The total amount of related DNA base pairs on Earth is estimated at 5.0 x 1037, and weighs 50 billion tonnes. In comparison, the total mass of the biosphere has been estimated to be as much as 4 TtC (trillion tons of carbon).
Question: How many species currently live on earth?

Output: Earth's current species range from 10 million to 14 million,

QUES: Norwegian researchers at the University of Troms have shown that some Arctic animals (ptarmigan, reindeer) show circadian rhythms only in the parts of the year that have daily sunrises and sunsets. In one study of reindeer, animals at 70 degrees North showed circadian rhythms in the autumn, winter and spring, but not in the summer. Reindeer on Svalbard at 78 degrees North showed such rhythms only in autumn and spring. The researchers suspect that other Arctic animals as well may not show circadian rhythms in the constant light of summer and the constant dark of winter.

What animals show circadian rythems during the costant light of summer?
What is the answer?
ANS: unanswerable

QUES: Ultimately, the New Orthophonic curve was disclosed in a publication by R.C. Moyer of RCA Victor in 1953. He traced RCA Victor characteristics back to the Western Electric "rubber line" recorder in 1925 up to the early 1950s laying claim to long-held recording practices and reasons for major changes in the intervening years. The RCA Victor New Orthophonic curve was within the tolerances for the NAB/NARTB, Columbia LP, and AES curves. It eventually became the technical predecessor to the RIAA curve.
Who developed the New Orthophonic curve?

ANS: RCA Victor

Tibetan music often involves chanting in Tibetan or Sanskrit, as an integral part of the religion. These chants are complex, often recitations of sacred texts or in celebration of various festivals. Yang chanting, performed without metrical timing, is accompanied by resonant drums and low, sustained syllables. Other styles include those unique to the various schools of Tibetan Buddhism, such as the classical music of the popular Gelugpa school, and the romantic music of the Nyingmapa, Sakyapa and Kagyupa schools.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What does Sanskrit music often involve?
Ah, so.. unanswerable

Question: In 1955, with both the United States and the Soviet Union building ballistic missiles that could be utilized to launch objects into space, the "starting line" was drawn for the Space Race. In separate announcements, just four days apart, both nations publicly announced that they would launch artificial Earth satellites by 1957 or 1958. On July 29, 1955, James C. Hagerty, president Dwight D. Eisenhower's press secretary, announced that the United States intended to launch "small Earth circling satellites" between July 1, 1957, and December 31, 1958, as part of their contribution to the International Geophysical Year (IGY). Four days later, at the Sixth Congress of International Astronautical Federation in Copenhagen, scientist Leonid I. Sedov spoke to international reporters at the Soviet embassy, and announced his country's intention to launch a satellite as well, in the "near future". On August 30, 1955, Korolev managed to get the Soviet Academy of Sciences to create a commission whose purpose was to beat the Americans into Earth orbit: this was the de facto start date for the Space Race. The Council of Ministers of the Soviet Union began a policy of treating development of its space program as a classified state secret.
Try to answer this question if possible: Who was president Dwight D. Eisenhower's press secretary?
Answer: James C. Hagerty

Context and question: Beer contains ethyl alcohol, the same chemical that is present in wine and distilled spirits and as such, beer consumption has short-term psychological and physiological effects on the user. Different concentrations of alcohol in the human body have different effects on a person. The effects of alcohol depend on the amount an individual has drunk, the percentage of alcohol in the beer and the timespan that the consumption took place, the amount of food eaten and whether an individual has taken other prescription, over-the-counter or street drugs, among other factors. Drinking enough to cause a blood alcohol concentration (BAC) of 0.03%-0.12% typically causes an overall improvement in mood and possible euphoria, increased self-confidence and sociability, decreased anxiety, a flushed, red appearance in the face and impaired judgment and fine muscle coordination. A BAC of 0.09% to 0.25% causes lethargy, sedation, balance problems and blurred vision. A BAC from 0.18% to 0.30% causes profound confusion, impaired speech (e.g., slurred speech), staggering, dizziness and vomiting. A BAC from 0.25% to 0.40% causes stupor, unconsciousness, anterograde amnesia, vomiting (death may occur due to inhalation of vomit (pulmonary aspiration) while unconscious and respiratory depression (potentially life-threatening). A BAC from 0.35% to 0.80% causes a coma (unconsciousness), life-threatening respiratory depression and possibly fatal alcohol poisoning. As with all alcoholic drinks, drinking while driving, operating an aircraft or heavy machinery increases the risk of an accident; many countries have penalties against drunk driving.
What type of alcohol is found in wine and distilled spirits?
Answer:
ethyl alcohol
