Input: Read this: The free trade spirit of the time received a strong augmentation through the development of a modern, effective stock market in the Low Countries. The Netherlands has the oldest stock exchange in the world, founded in 1602 by the Dutch East India Company. While Rotterdam has the oldest bourse in the Netherlands, the world's first stock exchange – that of the Dutch East-India Company – went public in six different cities. Later, a court ruled that the company had to reside legally in a single city, so Amsterdam is recognized as the oldest such institution based on modern trading principles. While the banking system evolved in the Low Countries, it was quickly incorporated by the well-connected English, stimulating English economic output.
Question: When was the oldest stock exchange founded in England?

Output: unanswerable


QUES: Sociologist Rodney Stark states that Jehovah's Witness leaders are "not always very democratic" and that members "are expected to conform to rather strict standards," but adds that "enforcement tends to be very informal, sustained by the close bonds of friendship within the group", and that Jehovah's Witnesses see themselves as "part of the power structure rather than subject to it." Sociologist Andrew Holden states that most members who join millenarian movements such as Jehovah's Witnesses have made an informed choice. However, he also states that defectors "are seldom allowed a dignified exit", and describes the administration as autocratic.

What statement does Stark make about the leaders of the Jehovah's Witnesses?
What is the answer?
ANS: "not always very democratic"


QUES: For many centuries, wealthy and powerful members of the szlachta sought to gain legal privileges over their peers. Few szlachta were wealthy enough to be known as magnates (karmazyni—the "Crimsons", from the crimson colour of their boots).

Question: Evidence suggests that blast furnaces, that convert raw iron ore into pig iron, which can be remelted in a cupola furnace to produce cast iron by means of a cold blast and hot blast, were operational in China by the late Spring and Autumn period (722–481 BC). The bloomery was nonexistent in ancient China; however, the Han-era Chinese produced wrought iron by injecting excess oxygen into a furnace and causing decarburization. Cast iron and pig iron could be converted into wrought iron and steel using a fining process.
Try to answer this question if possible: What element was used in the production of wrought iron?
Answer: oxygen


Input: Read this: Prokaryotes (bacteria and archaea) typically store their genomes on a single large, circular chromosome. Similarly, some eukaryotic organelles contain a remnant circular chromosome with a small number of genes.:14.4 Prokaryotes sometimes supplement their chromosome with additional small circles of DNA called plasmids, which usually encode only a few genes and are transferable between individuals. For example, the genes for antibiotic resistance are usually encoded on bacterial plasmids and can be passed between individual cells, even those of different species, via horizontal gene transfer.
Question: What type of chromosome do some eukaryotic organelles contain?

Output:
a remnant circular chromosome with a small number of genes
