The problem: Answer a question about this article:
Other widely used alloys that contain zinc include nickel silver, typewriter metal, soft and aluminium solder, and commercial bronze. Zinc is also used in contemporary pipe organs as a substitute for the traditional lead/tin alloy in pipes. Alloys of 85–88% zinc, 4–10% copper, and 2–8% aluminium find limited use in certain types of machine bearings. Zinc is the primary metal used in making American one cent coins since 1982. The zinc core is coated with a thin layer of copper to give the impression of a copper coin. In 1994, 33,200 tonnes (36,600 short tons) of zinc were used to produce 13.6 billion pennies in the United States.
What has zinc replaced in pipe organs?
****
The answer: lead/tin alloy


Problem: Please answer a question about the following article about Samurai:
Despite the rampant romanticism of the 20th century, samurai could be disloyal and treacherous (e.g., Akechi Mitsuhide), cowardly, brave, or overly loyal (e.g., Kusunoki Masashige). Samurai were usually loyal to their immediate superiors, who in turn allied themselves with higher lords. These loyalties to the higher lords often shifted; for example, the high lords allied under Toyotomi Hideyoshi (豊臣秀吉) were served by loyal samurai, but the feudal lords under them could shift their support to Tokugawa, taking their samurai with them. There were, however, also notable instances where samurai would be disloyal to their lord or daimyo, when loyalty to the Emperor was seen to have supremacy.
What sometimes overrode samurais' loyalty to the daimyo?
A: loyalty to the Emperor was seen to have supremacy

The first union was built on campus in 1926 as a campus community center. The unions are still the "living rooms" of campus today and include three locations – the Kansas Union and Burge Union at the Lawrence Campus and Jayhawk Central at the Edwards Campus. The KU Memorial Unions Corporation manages the KU Bookstore (with seven locations). The KU Bookstore is the official bookstore of KU. The Corporation also includes KU Dining Services, with more than 20 campus locations, including The Market (inside the Kansas Union) and The Underground (located in Wescoe Hall). The KU Bookstore and KU Dining Services are not-for-profit, with proceeds going back to support student programs, such as Student Union Activities.

What is the name of the student union on the Edwards Campus of KU?
Answer: Jayhawk Central


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?
The answer is the following: 1949

Here is a question about this article: Rajasthani cooking was influenced by both the war-like lifestyles of its inhabitants and the availability of ingredients in this arid region. Food that could last for several days and could be eaten without heating was preferred. The scarcity of water and fresh green vegetables have all had their effect on the cooking. It is known for its snacks like Bikaneri Bhujia. Other famous dishes include bajre ki roti (millet bread) and lashun ki chutney (hot garlic paste), mawa kachori Mirchi Bada, Pyaaj Kachori and ghevar from Jodhpur, Alwar ka Mawa(Milk Cake), malpauas from Pushkar and rassgollas from Bikaner. Originating from the Marwar region of the state is the concept Marwari Bhojnalaya, or vegetarian restaurants, today found in many parts of India, which offer vegetarian food of the Marwari people. 4 Dal-Bati-Churma is very popular in Rajasthan. The traditional way to serve it is to first coarsely mash the Baati then pour pure Ghee on top of it. It is served with the daal (lentils) and spicy garlic chutney. Also served with Besan (gram flour) ki kadi. It is commonly served at all festivities, including religious occasions, wedding ceremonies, and birthday parties in Rajasthan. "Dal-Baati-Churma", is a combination of three different food items — Daal (lentils), Baati and Churma (Sweet). It is a typical Rajasthani dish.
What is the answer to this question: Along with scarce green vegetables, what had an impact on Rajasthani cooking?
****
So...
scarcity of water
