Problem: Catalan language:

Catalan shares many traits with the other neighboring Romance languages (Italian, Sardinian, Occitan, and Spanish). However, despite being mostly situated in the Iberian Peninsula, Catalan has marked differences with the Ibero-Romance group (Spanish and Portuguese) in terms of pronunciation, grammar, and especially vocabulary; showing instead its closest affinity with Occitan and to a lesser extent Gallo-Romance (French, Franco-Provencal, Gallo-Italian).

To what group is Catalan most closely related?

A: Occitan

Problem: Stochastic computing was first introduced in a pioneering paper by von Neumann in 1953. However, the theory could not be implemented until advances in computing of the 1960s. He also created the field of cellular automata without the aid of computers, constructing the first self-replicating automata with pencil and graph paper. The concept of a universal constructor was fleshed out in his posthumous work Theory of Self Reproducing Automata. Von Neumann proved that the most effective way of performing large-scale mining operations such as mining an entire moon or asteroid belt would be by using self-replicating spacecraft, taking advantage of their exponential growth. His rigorous mathematical analysis of the structure of self-replication (of the semiotic relationship between constructor, description and that which is constructed), preceded the discovery of the structure of DNA. Beginning in 1949, von Neumann's design for a self-reproducing computer program is considered the world's first computer virus, and he is considered to be the theoretical father of computer virology.
When did von NEumann develop first self reproducing computer program?

Answer: 1949

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
There are many different patterns of gas exchange demonstrated by different groups of insects. Gas exchange patterns in insects can range from continuous and diffusive ventilation, to discontinuous gas exchange.:6568 During continuous gas exchange, oxygen is taken in and carbon dioxide is released in a continuous cycle. In discontinuous gas exchange, however, the insect takes in oxygen while it is active and small amounts of carbon dioxide are released when the insect is at rest. Diffusive ventilation is simply a form of continuous gas exchange that occurs by diffusion rather than physically taking in the oxygen. Some species of insect that are submerged also have adaptations to aid in respiration. As larvae, many insects have gills that can extract oxygen dissolved in water, while others need to rise to the water surface to replenish air supplies which may be held or trapped in special structures.
What kind of exchange is demonstrated by different insects?
A: gas exchange

Context and question: Emotions are thought to be related to certain activities in brain areas that direct our attention, motivate our behavior, and determine the significance of what is going on around us. Pioneering work by Broca (1878), Papez (1937), and MacLean (1952) suggested that emotion is related to a group of structures in the center of the brain called the limbic system, which includes the hypothalamus, cingulate cortex, hippocampi, and other structures. More recent research has shown that some of these limbic structures are not as directly related to emotion as others are while some non-limbic structures have been found to be of greater emotional relevance.
Along with the cingulate cortex and hippocampi, what structure is a notable part of the limbic system?
Answer: hypothalamus

Question: In Germany, groups such as Einsturzende Neubauten developed a unique style of industrial music, utilizing avant-garde noise, homemade instruments and found objects. Members of that group would later go on to collaborate with members of the Birthday Party. In Brazil, the post-punk scene grew after the generation of Brasilia rock with bands such as Legiao Urbana, Capital Inicial and Plebe Rude and then the opening of the music club Madame Sata in Sao Paulo, with acts like Cabine C, Titas, Patife Band, Fellini and Mercenarias, as documented on compilations like The Sexual Life of the Savages and the Nao Wave/Nao Sao Paulo series, released in the UK, Germany and Brazil, respectively.[citation needed]
Is there an answer to this question: What country had a post-punk scene after a generation of rock?

Answer: Brazil

Montana contains thousands of named rivers and creeks, 450 miles (720 km) of which are known for "blue-ribbon" trout fishing. Montana's water resources provide for recreation, hydropower, crop and forage irrigation, mining, and water for human consumption. Montana is one of few geographic areas in the world whose rivers form parts of three major watersheds (i.e. where two continental divides intersect). Its rivers feed the Pacific Ocean, the Gulf of Mexico, and Hudson Bay. The watersheds divide at Triple Divide Peak in Glacier National Park.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What ocean do rivers flow into from Montana?
Ah, so..
Pacific Ocean
