Input: Read this: A Federal Trade Commission report issued in 1958 attempted to quantify the effect of antibiotic development on American public health. The report found that over the period 1946-1955, there was a 42% drop in the incidence of diseases for which antibiotics were effective and only a 20% drop in those for which antibiotics were not effective. The report concluded that "it appears that the use of antibiotics, early diagnosis, and other factors have limited the epidemic spread and thus the number of these diseases which have occurred". The study further examined mortality rates for eight common diseases for which antibiotics offered effective therapy (syphilis, tuberculosis, dysentery, scarlet fever, whooping cough, meningococcal infections, and pneumonia), and found a 56% decline over the same period. Notable among these was a 75% decline in deaths due to tuberculosis.
Question: What were nine diseases examined for?

Output: unanswerable


QUES: The earliest recorded account of a circadian process dates from the 4th century B.C.E., when Androsthenes, a ship captain serving under Alexander the Great, described diurnal leaf movements of the tamarind tree. The observation of a circadian or diurnal process in humans is mentioned in Chinese medical texts dated to around the 13th century, including the Noon and Midnight Manual and the Mnemonic Rhyme to Aid in the Selection of Acu-points According to the Diurnal Cycle, the Day of the Month and the Season of the Year.

What is the earliest recorded instance of circadian rhythm?
What is the answer?
ANS: 4th century B.C.E


QUES: There is consensus that the military regime in Myanmar is one of the world's most repressive and abusive regimes. In November 2012, Samantha Power, Barack Obama's Special Assistant to the President on Human Rights, wrote on the White House blog in advance of the president's visit that "Serious human rights abuses against civilians in several regions continue, including against women and children." Members of the United Nations and major international human rights organisations have issued repeated and consistent reports of widespread and systematic human rights violations in Myanmar. The United Nations General Assembly has repeatedly called on the Burmese Military Junta to respect human rights and in November 2009 the General Assembly adopted a resolution "strongly condemning the ongoing systematic violations of human rights and fundamental freedoms" and calling on the Burmese Military Regime "to take urgent measures to put an end to violations of international human rights and humanitarian law."
Who is Samantha Power?

ANS: Barack Obama's Special Assistant to the President on Human Rights


Cardinal bishops (cardinals of the episcopal order) are among the most senior prelates of the Catholic Church. Though in modern times most cardinals are also bishops, the term "cardinal bishop" only refers to the cardinals who are titular bishops of one of the "suburbicarian" sees.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): Who is among the most junior prelates of the Catholic Church?
Ah, so.. unanswerable


Question: Chemical defense is another important defense found amongst species of Coleoptera and Lepidoptera, usually being advertised by bright colors, such as the Monarch butterfly. They obtain their toxicity by sequestering the chemicals from the plants they eat into their own tissues. Some Lepidoptera manufacture their own toxins. Predators that eat poisonous butterflies and moths may become sick and vomit violently, learning not to eat those types of species; this is actually the basis of Müllerian mimicry. A predator who has previously eaten a poisonous lepidopteran may avoid other species with similar markings in the future, thus saving many other species as well. Some ground beetles of the Carabidae family can spray chemicals from their abdomen with great accuracy, to repel predators.
Try to answer this question if possible: Insects become toxic by doing what with the chemicals from plants?
Answer: sequestering


Input: Read this: The first blue-violet LED using magnesium-doped gallium nitride was made at Stanford University in 1972 by Herb Maruska and Wally Rhines, doctoral students in materials science and engineering. At the time Maruska was on leave from RCA Laboratories, where he collaborated with Jacques Pankove on related work. In 1971, the year after Maruska left for Stanford, his RCA colleagues Pankove and Ed Miller demonstrated the first blue electroluminescence from zinc-doped gallium nitride, though the subsequent device Pankove and Miller built, the first actual gallium nitride light-emitting diode, emitted green light. In 1974 the U.S. Patent Office awarded Maruska, Rhines and Stanford professor David Stevenson a patent for their work in 1972 (U.S. Patent US3819974 A) and today magnesium-doping of gallium nitride continues to be the basis for all commercial blue LEDs and laser diodes. These devices built in the early 1970s had too little light output to be of practical use and research into gallium nitride devices slowed. In August 1989, Cree introduced the first commercially available blue LED based on the indirect bandgap semiconductor, silicon carbide (SiC). SiC LEDs had very low efficiency, no more than about 0.03%, but did emit in the blue portion of the visible light spectrum.[citation needed]
Question: What substance helped demonstrate the first blue electroluminescence?

Output:
zinc-doped gallium nitride
