Problem: Karl Popper:

Karl Popper's rejection of Marxism during his teenage years left a profound mark on his thought. He had at one point joined a socialist association, and for a few months in 1919 considered himself a communist. During this time he became familiar with the Marxist view of economics, class-war, and history. Although he quickly became disillusioned with the views expounded by Marxism, his flirtation with the ideology led him to distance himself from those who believed that spilling blood for the sake of a revolution was necessary. He came to realise that when it came to sacrificing human lives, one was to think and act with extreme prudence.

For a time during which year did Popper consider himself a communist?
---
A: 1919


Problem: Botany:

In 1998 the Angiosperm Phylogeny Group published a phylogeny for flowering plants based on an analysis of DNA sequences from most families of flowering plants. As a result of this work, many questions, such as which families represent the earliest branches of angiosperms, have now been answered. Investigating how plant species are related to each other allows botanists to better understand the process of evolution in plants. Despite the study of model plants and increasing use of DNA evidence, there is ongoing work and discussion among taxonomists about how best to classify plants into various taxa. Technological developments such as computers and electron microscopes have greatly increased the level of detail studied and speed at which data can be analysed.

What was the first plant grouping based on DNA sequencing?
---
A: flowering plants


Problem: University:

Examining the influence of humanism on scholars in medicine, mathematics, astronomy and physics may suggest that humanism and universities were a strong impetus for the scientific revolution. Although the connection between humanism and the scientific discovery may very well have begun within the confines of the university, the connection has been commonly perceived as having been severed by the changing nature of science during the scientific revolution. Historians such as Richard S. Westfall have argued that the overt traditionalism of universities inhibited attempts to re-conceptualize nature and knowledge and caused an indelible tension between universities and scientists. This resistance to changes in science may have been a significant factor in driving many scientists away from the university and toward private benefactors, usually in princely courts, and associations with newly forming scientific societies.

The study of humanism among those studying history is said to have caused what?
---
A: unanswerable


Problem: Translation:

Mark Twain provided humorously telling evidence for the frequent unreliability of back-translation when he issued his own back-translation of a French translation of his short story, "The Celebrated Jumping Frog of Calaveras County". He published his back-translation in a 1903 volume together with his English-language original, the French translation, and a "Private History of the 'Jumping Frog' Story". The latter included a synopsized adaptation of his story that Twain stated had appeared, unattributed to Twain, in a Professor Sidgwick’s Greek Prose Composition (p. 116) under the title, "The Athenian and the Frog"; the adaptation had for a time been taken for an independent ancient Greek precursor to Twain's "Jumping Frog" story.

What had been thought for a while to be an independent ancient Greek precursor to Twain's story?
---
A:
"The Athenian and the Frog"
