Input: Read this: Some organisms, such as the lichen Trapelia involuta or microorganisms such as the bacterium Citrobacter, can absorb concentrations of uranium that are up to 300 times the level of their environment. Citrobacter species absorb uranyl ions when given glycerol phosphate (or other similar organic phosphates). After one day, one gram of bacteria can encrust themselves with nine grams of uranyl phosphate crystals; this creates the possibility that these organisms could be used in bioremediation to decontaminate uranium-polluted water. The proteobacterium Geobacter has also been shown to bioremediate uranium in ground water. The mycorrhizal fungus Glomus intraradices increases uranium content in the roots of its symbiotic plant.
Question: What fungus is known to cause uranium content in its symbiotic plant roots to increase?

Output: Glomus intraradices


QUES: The kingdom is mentioned in the Periplus of the Erythraean Sea as an important market place for ivory, which was exported throughout the ancient world. Aksum was at the time ruled by Zoskales, who also governed the port of Adulis. The Aksumite rulers facilitated trade by minting their own Aksumite currency. The state also established its hegemony over the declining Kingdom of Kush and regularly entered the politics of the kingdoms on the Arabian peninsula, eventually extending its rule over the region with the conquest of the Himyarite Kingdom.

What product did the Kingdom of Kush export?
What is the answer?
ANS: unanswerable


QUES: On Saturday September 6, 1997 the formal, though not "state" Funeral of Diana, Princess of Wales, was held. It was a royal ceremonial funeral including royal pageantry and Anglican funeral liturgy. A Second Public service was held on Sunday at the demand of the people. The burial occurred privately later the same day. Diana's former husband, sons, mother, siblings, a close friend, and a clergyman were present. Diana's body was clothed in a black long-sleeved dress designed by Catherine Walker, which she had chosen some weeks before. A set of rosary beads was placed in her hands, a gift she had received from Mother Teresa. Her grave is on the grounds of her family estate, Althorp, on a private island.[citation needed]
When was the formal funeral of Diana, Prince of Wales?

ANS: unanswerable


On the shores of the strait, in 1701, the French officer Antoine de la Mothe Cadillac, along with fifty-one French people and French Canadians, founded a settlement called Fort Pontchartrain du Détroit, naming it after Louis Phélypeaux, comte de Pontchartrain, Minister of Marine under Louis XIV. France offered free land to colonists to attract families to Detroit; when it reached a total population of 800 in 1765, it was the largest city between Montreal and New Orleans, both also French settlements. By 1773, the population of Detroit was 1,400. By 1778, its population was up to 2,144 and it was the third-largest city in the Province of Quebec.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What was Detroit's population in 1773?
Ah, so.. 1,400


Question: Among the challenges being faced to improve the efficiency of LED-based white light sources is the development of more efficient phosphors. As of 2010, the most efficient yellow phosphor is still the YAG phosphor, with less than 10% Stoke shift loss. Losses attributable to internal optical losses due to re-absorption in the LED chip and in the LED packaging itself account typically for another 10% to 30% of efficiency loss. Currently, in the area of phosphor LED development, much effort is being spent on optimizing these devices to higher light output and higher operation temperatures. For instance, the efficiency can be raised by adapting better package design or by using a more suitable type of phosphor. Conformal coating process is frequently used to address the issue of varying phosphor thickness.
Try to answer this question if possible: What is the percentage of stoke shift loss in YAG phosphor?
Answer: less than 10%


Context and question: Higher education, also called tertiary, third stage, or postsecondary education, is the non-compulsory educational level that follows the completion of a school such as a high school or secondary school. Tertiary education is normally taken to include undergraduate and postgraduate education, as well as vocational education and training. Colleges and universities mainly provide tertiary education. Collectively, these are sometimes known as tertiary institutions. Individuals who complete tertiary education generally receive certificates, diplomas, or academic degrees.
People do not receive certificates from what level of education?
Answer:
unanswerable
