Problem: Alaska:

The Alaska Native Language Center at the University of Alaska Fairbanks claims that at least 20 Alaskan native languages exist and there are also some languages with different dialects. Most of Alaska's native languages belong to either the Eskimo–Aleut or Na-Dene language families however some languages are thought to be isolates (e.g. Haida) or have not yet been classified (e.g. Tsimshianic). As of 2014[update] nearly all of Alaska's native languages were classified as either threatened, shifting, moribund, nearly extinct, or dormant languages.

At least how many native Alaskan languages exist, according to the Alaska Native Language Center?

A: at least 20


Problem: Somerset has a high indigenous British population, with 98.8% registering as white British and 92.4% of these as born in the United Kingdom. Chinese is the largest ethnic group, while the black minority ethnic proportion of the total population is 2.9%. Over 25% of Somerset's population is concentrated in Taunton, Bridgwater and Yeovil. The rest of the county is rural and sparsely populated. Over 9 million tourist nights are spent in Somerset each year, which significantly increases the population at peak times.
What percentage of the population is native

Context and question: Indigenous genetic studies suggest that the first inhabitants of the Americas share a single ancestral population, one that developed in isolation, conjectured to be Beringia. The isolation of these peoples in Beringia might have lasted 10–20,000 years. Around 16,500 years ago, the glaciers began melting, allowing people to move south and east into Canada and beyond. These people are believed to have followed herds of now-extinct Pleistocene megafauna along ice-free corridors that stretched between the Laurentide and Cordilleran Ice Sheets.
What did the people follow in the corridors between the ice sheets?
Answer: Pleistocene megafauna


Question: Tuberculosis is classified as one of the granulomatous inflammatory diseases. Macrophages, T lymphocytes, B lymphocytes, and fibroblasts aggregate to form granulomas, with lymphocytes surrounding the infected macrophages. When other macrophages attack the infected macrophage, they fuse together to form a giant multinucleated cell in the alveolar lumen. The granuloma may prevent dissemination of the mycobacteria and provide a local environment for interaction of cells of the immune system. However, more recent evidence suggests that the bacteria use the granulomas to avoid destruction by the host's immune system. Macrophages and dendritic cells in the granulomas are unable to present antigen to lymphocytes; thus the immune response is suppressed. Bacteria inside the granuloma can become dormant, resulting in latent infection. Another feature of the granulomas is the development of abnormal cell death (necrosis) in the center of tubercles. To the naked eye, this has the texture of soft, white cheese and is termed caseous necrosis.
Is there an answer to this question: What is used by bacteria to destroy the host's immune system?

Answer: unanswerable


Problem: Republic of the Congo:

Transport in the Republic of the Congo includes land, air and water transportation. The country's rail system was built by forced laborers during the 1930s and largely remains in operation. There are also over 1000 km of paved roads and two major international airports (Maya-Maya Airport and Pointe Noire Airport) which have flights to Paris and many African cities. The country also has a large port on the Atlantic Ocean at Pointe-Noire and others along the Congo River at Brazzaville and Impfondo.
