Problem: Some insects use parthenogenesis, a process in which the female can reproduce and give birth without having the eggs fertilized by a male. Many aphids undergo a form of parthenogenesis, called cyclical parthenogenesis, in which they alternate between one or many generations of asexual and sexual reproduction. In summer, aphids are generally female and parthenogenetic; in the autumn, males may be produced for sexual reproduction. Other insects produced by parthenogenesis are bees, wasps and ants, in which they spawn males. However, overall, most individuals are female, which are produced by fertilization. The males are haploid and the females are diploid. More rarely, some insects display hermaphroditism, in which a given individual has both male and female reproductive organs.
How many insects use parthenogenesis?

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
The structure of Bern's city centre is largely medieval and has been recognised by UNESCO as a Cultural World Heritage Site. Perhaps its most famous sight is the Zytglogge (Bernese German for "Time Bell"), an elaborate medieval clock tower with moving puppets. It also has an impressive 15th century Gothic cathedral, the Munster, and a 15th-century town hall. Thanks to 6 kilometres (4 miles) of arcades, the old town boasts one of the longest covered shopping promenades in Europe.
What type of cathedral is Muster?
A: Gothic

Context and question: Napoleon's noble, moderately affluent background afforded him greater opportunities to study than were available to a typical Corsican of the time. In January 1779, he was enrolled at a religious school in Autun. In May, he was admitted to a military academy at Brienne-le-Chateau. His first language was Corsican, and he always spoke French with a marked Corsican accent and never learned to spell French properly. He was teased by other students for his accent and applied himself to reading. An examiner observed that Napoleon "has always been distinguished for his application in mathematics. He is fairly well acquainted with history and geography... This boy would make an excellent sailor."[note 3]
When did Napoleon begin religious schooling in Autun?
Answer: January 1779

Question: Christian Marian perspectives include a great deal of diversity. While some Christians such as Roman Catholics and Eastern Orthodox have well established Marian traditions, Protestants at large pay scant attention to Mariological themes. Roman Catholic, Eastern Orthodox, Oriental Orthodox, Anglican, and Lutherans venerate the Virgin Mary. This veneration especially takes the form of prayer for intercession with her Son, Jesus Christ. Additionally it includes composing poems and songs in Mary's honor, painting icons or carving statues of her, and conferring titles on Mary that reflect her position among the saints.
Is there an answer to this question: Who do the saints compose poems and songs about?

Answer: unanswerable

QUES: Due to the top secret nature of the work, Los Alamos was isolated. In Feynman's own words, "There wasn't anything to do there." Bored, he indulged his curiosity by learning to pick the combination locks on cabinets and desks used to secure papers. Feynman played many jokes on colleagues. In one case he found the combination to a locked filing cabinet by trying the numbers he thought a physicist would use (it proved to be 271828 after the base of natural logarithms, e = 2.71828...), and found that the three filing cabinets where a colleague kept a set of atomic bomb research notes all had the same combination. He left a series of notes in the cabinets as a prank, which initially spooked his colleague, Frederic de Hoffmann, into thinking a spy or saboteur had gained access to atomic bomb secrets. On several occasions, Feynman drove to Albuquerque to see his ailing wife in a car borrowed from Klaus Fuchs, who was later discovered to be a real spy for the Soviets, transporting nuclear secrets in his car to Santa Fe.
