Input: Read this: Earthworms are Oligochaetes that support terrestrial food chains both as prey and in some regions are important in aeration and enriching of soil. The burrowing of marine polychaetes, which may constitute up to a third of all species in near-shore environments, encourages the development of ecosystems by enabling water and oxygen to penetrate the sea floor. In addition to improving soil fertility, annelids serve humans as food and as bait. Scientists observe annelids to monitor the quality of marine and fresh water. Although blood-letting is no longer in favor with doctors, some leech species are regarded as endangered species because they have been over-harvested for this purpose in the last few centuries. Ragworms' jaws are now being studied by engineers as they offer an exceptional combination of lightness and strength.
Question: How do burrowing marine annelids remove ocean ecosystems?

Output: unanswerable


QUES: As of 2011, 235–330 million people worldwide are affected by asthma, and approximately 250,000–345,000 people die per year from the disease. Rates vary between countries with prevalences between 1 and 18%. It is more common in developed than developing countries. One thus sees lower rates in Asia, Eastern Europe and Africa. Within developed countries it is more common in those who are economically disadvantaged while in contrast in developing countries it is more common in the affluent. The reason for these differences is not well known. Low and middle income countries make up more than 80% of the mortality.

By 2011, how many people were affected by asthma?
What is the answer?
ANS: 235–330 million people worldwide are affected by asthma


QUES: During the 19th century, Paris was the home and subject for some of France's greatest writers, including Charles Baudelaire, Stéphane Mallarmé, Mérimée, Alfred de Musset, Marcel Proust, Émile Zola, Alexandre Dumas, Gustave Flaubert, Guy de Maupassant and Honoré de Balzac. Victor Hugo's The Hunchback of Notre Dame inspired the renovation of its setting, the Notre-Dame de Paris. Another of Victor Hugo's works, Les Misérables, written while he was in exile outside France during the Second Empire, described the social change and political turmoil in Paris in the early 1830s. One of the most popular of all French writers, Jules Verne, worked at the Theatre Lyrique and the Paris stock exchange, while he did research for his stories at the National Library.
During what period of time was Victor Hugo exiled from France?

ANS: Second Empire


Hydrogen's rarer isotopes also each have specific applications. Deuterium (hydrogen-2) is used in nuclear fission applications as a moderator to slow neutrons, and in nuclear fusion reactions. Deuterium compounds have applications in chemistry and biology in studies of reaction isotope effects. Tritium (hydrogen-3), produced in nuclear reactors, is used in the production of hydrogen bombs, as an isotopic label in the biosciences, and as a radiation source in luminous paints.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What is tritium used for?
Ah, so.. production of hydrogen bombs, as an isotopic label in the biosciences, and as a radiation source in luminous paints


Question: Later Indian materialist Jayaraashi Bhatta (6th century) in his work Tattvopaplavasimha ("The upsetting of all principles") refuted the Nyaya Sutra epistemology. The materialistic Cārvāka philosophy appears to have died out some time after 1400. When Madhavacharya compiled Sarva-darśana-samgraha (a digest of all philosophies) in the 14th century, he had no Cārvāka/Lokāyata text to quote from, or even refer to.
Try to answer this question if possible: When was Jayaraashi Bhatta born?
Answer: unanswerable
