Problem: Uranium:

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.

What lichen is known to absorb a uranium concentration nearly 300 times higher than the amount in the environment?
---
A: Trapelia involuta

Problem: History of science:

Ibn Sina (Avicenna) is regarded as the most influential philosopher of Islam. He pioneered the science of experimental medicine and was the first physician to conduct clinical trials. His two most notable works in medicine are the Kitab al-shifa ("Book of Healing") and The Canon of Medicine, both of which were used as standard medicinal texts in both the Muslim world and in Europe well into the 17th century. Amongst his many contributions are the discovery of the contagious nature of infectious diseases, and the introduction of clinical pharmacology.

What characteristic did Ibn Sina find out about infectious diseases?
---
A: contagious

Problem: Spectre (2015 film):

The song was released as a digital download on 25 September 2015. It received mixed reviews from critics and fans, particularly in comparison to Adele's "Skyfall". The mixed reception to the song led to Shirley Bassey trending on Twitter on the day it was released. It became the first Bond theme to reach number one in the UK Singles Chart. The English band Radiohead also composed a song for the film, which went unused.

Radiohead composed what which was used in the film?

A: unanswerable

Problem: George VI:

George VI's reign saw the acceleration of the dissolution of the British Empire. The Statute of Westminster 1931 had already acknowledged the evolution of the Dominions into separate sovereign states. The process of transformation from an empire to a voluntary association of independent states, known as the Commonwealth, gathered pace after the Second World War. During the ministry of Clement Attlee, British India became the two independent dominions of India and Pakistan in 1947. George relinquished the title of Emperor of India, and became King of India and King of Pakistan instead. In 1950 he ceased to be King of India when it became a republic within the Commonwealth of Nations, but he remained King of Pakistan until his death and India recognised his new title of Head of the Commonwealth. Other countries left the Commonwealth, such as Burma in January 1948, Palestine (divided between Israel and the Arab states) in May 1948 and the Republic of Ireland in 1949.

In what year did the Second World War end?
---
A:
unanswerable
