Input: Read this: Other supportive evidence includes: a 20% difference in peak expiratory flow rate on at least three days in a week for at least two weeks, a 20% improvement of peak flow following treatment with either salbutamol, inhaled corticosteroids or prednisone, or a 20% decrease in peak flow following exposure to a trigger. Testing peak expiratory flow is more variable than spirometry, however, and thus not recommended for routine diagnosis. It may be useful for daily self-monitoring in those with moderate to severe disease and for checking the effectiveness of new medications. It may also be helpful in guiding treatment in those with acute exacerbations.
Question: When may prednisone also be helpful in spirometry?

Output: unanswerable

Input: Read this: The plan stated that the following numbers of species of different groups had been recorded from Egypt: algae (1483 species), animals (about 15,000 species of which more than 10,000 were insects), fungi (more than 627 species), monera (319 species), plants (2426 species), protozoans (371 species). For some major groups, for example lichen-forming fungi and nematode worms, the number was not known. Apart from small and well-studied groups like amphibians, birds, fish, mammals and reptiles, the many of those numbers are likely to increase as further species are recorded from Egypt. For the fungi, including lichen-forming species, for example, subsequent work has shown that over 2200 species have been recorded from Egypt, and the final figure of all fungi actually occurring in the country is expected to be much higher.
Question: How many species of algae were recorded in Egypt?

Output: 1483

Input: Read this: The Hanover Zoo is one of the most spectacular and best zoos in Europe. The zoo received the Park Scout Award for the fourth year running in 2009/10, placing it among the best zoos in Germany. The zoo consists of several theme areas: Sambesi, Meyers Farm, Gorilla-Mountain, Jungle-Palace, and Mullewapp. Some smaller areas are Australia, the wooded area for wolves, and the so-called swimming area with many seabirds. There is also a tropical house, a jungle house, and a show arena. The new Canadian-themed area, Yukon Bay, opened in 2010. In 2010 the Hanover Zoo had over 1.6 million visitors.
Question: What area of the zoo does not host seabirds?

Output: unanswerable

Input: Read this: The Negritos are believed to be the first inhabitants of Southeast Asia. Once inhabiting Taiwan, Vietnam, and various other parts of Asia, they are now confined primarily to Thailand, the Malay Archipelago, and the Andaman and Nicobar Islands. Negrito means "little black people" in Spanish (negrito is the Spanish diminutive of negro, i.e., "little black person"); it is what the Spaniards called the short-statured, hunter-gatherer autochthones that they encountered in the Philippines. Despite this, Negritos are never referred to as black today, and doing so would cause offense. The term Negrito itself has come under criticism in countries like Malaysia, where it is now interchangeable with the more acceptable Semang, although this term actually refers to a specific group. The common Thai word for Negritos literally means "frizzy hair".
Question: Where do the Negritos reside currently?

Output:
Thailand, the Malay Archipelago, and the Andaman and Nicobar Islands.
