Problem: Tennessee:

Stretching west from the Blue Ridge for approximately 55 miles (89 km) is the Ridge and Valley region, in which numerous tributaries join to form the Tennessee River in the Tennessee Valley. This area of Tennessee is covered by fertile valleys separated by wooded ridges, such as Bays Mountain and Clinch Mountain. The western section of the Tennessee Valley, where the depressions become broader and the ridges become lower, is called the Great Valley. In this valley are numerous towns and two of the region's three urban areas, Knoxville, the 3rd largest city in the state, and Chattanooga, the 4th largest city in the state. The third urban area, the Tri-Cities, comprising Bristol, Johnson City, and Kingsport and their environs, is located to the northeast of Knoxville.

Which city is Tennessee's fourth largest?

Problem: Victoria was physically unprepossessingshe was stout, dowdy and no more than five feet tallbut she succeeded in projecting a grand image. She experienced unpopularity during the first years of her widowhood, but was well liked during the 1880s and 1890s, when she embodied the empire as a benevolent matriarchal figure. Only after the release of her diary and letters did the extent of her political influence become known to the wider public. Biographies of Victoria written before much of the primary material became available, such as Lytton Strachey's Queen Victoria of 1921, are now considered out of date. The biographies written by Elizabeth Longford and Cecil Woodham-Smith, in 1964 and 1972 respectively, are still widely admired. They, and others, conclude that as a person Victoria was emotional, obstinate, honest, and straight-talking.
When were the best biographies of Queen Victoria written?

Answer: 1964 and 1972

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
Many environmental factors have been associated with asthma's development and exacerbation including allergens, air pollution, and other environmental chemicals. Smoking during pregnancy and after delivery is associated with a greater risk of asthma-like symptoms. Low air quality from factors such as traffic pollution or high ozone levels, has been associated with both asthma development and increased asthma severity. Exposure to indoor volatile organic compounds may be a trigger for asthma; formaldehyde exposure, for example, has a positive association. Also, phthalates in certain types of PVC are associated with asthma in children and adults.
What two things are associated with a greater risk of symtoms from phtalates?
A: unanswerable

Context and question: The religious art of Nepal and Kathmandu in particular consists of an iconic symbolism of the Mother Goddesses such as: Bhavani, Durga, Gaja-Lakshmi, Hariti-Sitala, Mahsishamardini, Saptamatrika (seven mother goddesses), and Sri-Lakshmi(wealth-goddess). From the 3rd century BC, apart from the Hindu gods and goddesses, Buddhist monuments from the Ashokan period (it is said that Ashoka visited Nepal in 250 BC) have embellished Nepal in general and the valley in particular. These art and architectural edifices encompass three major periods of evolution: the Licchavi or classical period (500 to 900 AD), the post-classical period (1000 to 1400 AD), with strong influence of the Palla art form; the Malla period (1400 onwards) that exhibited explicitly tantric influences coupled with the art of Tibetan Demonology.
What is another name for the Licchavi period?
Answer: classical

Question: The complete technical disclosure of the Columbia LP by Peter C. Goldmark, Rene' Snepvangers and William S. Bachman in 1949 made it possible for a great variety of record companies to get into the business of making long playing records. The business grew quickly and interest spread in high fidelity sound and the do-it-yourself market for pickups, turntables, amplifier kits, loudspeaker enclosure plans, and AM/FM radio tuners. The LP record for longer works, 45 rpm for pop music, and FM radio became high fidelity program sources in demand. Radio listeners heard recordings broadcast and this in turn generated more record sales. The industry flourished.
Is there an answer to this question: What aided in records sales in the 1950s?

Answer: Radio listeners heard recordings broadcast

Question: TB infection begins when the mycobacteria reach the pulmonary alveoli, where they invade and replicate within endosomes of alveolar macrophages. Macrophages identify the bacterium as foreign and attempt to eliminate it by phagocytosis. During this process, the bacterium is enveloped by the macrophage and stored temporarily in a membrane-bound vesicle called a phagosome. The phagosome then combines with a lysosome to create a phagolysosome. In the phagolysosome, the cell attempts to use reactive oxygen species and acid to kill the bacterium. However, M. tuberculosis has a thick, waxy mycolic acid capsule that protects it from these toxic substances. M. tuberculosis is able to reproduce inside the macrophage and will eventually kill the immune cell.
Is there an answer to this question: What replicates inside the pulmonary alveoli?

Answer:
unanswerable
