Here is a question about this article: Poultry is the second most widely eaten type of meat in the world, accounting for about 30% of total meat production worldwide compared to pork at 38%. Sixteen billion birds are raised annually for consumption, more than half of these in industrialised, factory-like production units. Global broiler meat production rose to 84.6 million tonnes in 2013. The largest producers were the United States (20%), China (16.6%), Brazil (15.1%) and the European Union (11.3%). There are two distinct models of production; the European Union supply chain model seeks to supply products which can be traced back to the farm of origin. This model faces the increasing costs of implementing additional food safety requirements, welfare issues and environmental regulations. In contrast, the United States model turns the product into a commodity.
What is the answer to this question: How many industry models are followed for the production process of poultry?
****
So... There are two distinct models of production;


Here is a question about this article: Von Neumann worked on lattice theory between 1937 and 1939. Von Neumann provided an abstract exploration of dimension in completed complemented modular topological lattices: "Dimension is determined, up to a positive linear transformation, by the following two properties. It is conserved by perspective mappings ("perspectivities") and ordered by inclusion. The deepest part of the proof concerns the equivalence of perspectivity with "projectivity by decomposition"—of which a corollary is the transitivity of perspectivity." Garrett Birkhoff writes: "John von Neumann's brilliant mind blazed over lattice theory like a meteor".
What is the answer to this question: What did von Neumann work on in 1937 - 39?
****
So... lattice theory


Here is a question about this article: In 1393 King Richard II compelled landlords to erect signs outside their premises. The legislation stated "Whosoever shall brew ale in the town with intention of selling it must hang out a sign, otherwise he shall forfeit his ale." This was to make alehouses easily visible to passing inspectors, borough ale tasters, who would decide the quality of the ale they provided. William Shakespeare's father, John Shakespeare, was one such inspector.
What is the answer to this question: If an ale-seller refused to post a sign, what punishment would he receive?
****
So...
forfeit his ale
