input question: Extract the answer to the question from the following context. Question: What was the cornerstone of Dell's business model? Context: Dell had a reputation as a company that relied upon supply chain efficiencies to sell established technologies at low prices, instead of being an innovator. By the mid-2000s many analysts were looking to innovating companies as the next source of growth in the technology sector. Dell's low spending on R&D relative to its revenue (compared to IBM, Hewlett Packard, and Apple Inc.)which worked well in the commoditized PC marketprevented it from making inroads into more lucrative segments, such as MP3 players and later mobile devices. Increasing spending on R&D would have cut into the operating margins that the company emphasized. Dell had done well with a horizontal organization that focused on PCs when the computing industry moved to horizontal mix-and-match layers in the 1980s, but by the mid-2000 the industry shifted to vertically integrated stacks to deliver complete IT solutions and Dell lagged far behind competitors like Hewlett Packard and Oracle.???

Q: Extract the answer to the question from the following context. Question: Obesity is seen as? Context: Obesity can unfavourably alter hormonal and metabolic status via resistance to the hormone leptin, and a vicious cycle may occur in which insulin/leptin resistance and obesity aggravate one another. The vicious cycle is putatively fuelled by continuously high insulin/leptin stimulation and fat storage, as a result of high intake of strongly insulin/leptin stimulating foods and energy. Both insulin and leptin normally function as satiety signals to the hypothalamus in the brain; however, insulin/leptin resistance may reduce this signal and therefore allow continued overfeeding despite large body fat stores. In addition, reduced leptin signalling to the brain may reduce leptin's normal effect to maintain an appropriately high metabolic rate.
A: body fat

Context: When Internet hunting was introduced in 2005, allowing people to hunt over the Internet using remotely controlled guns, the practice was widely criticised by hunters as violating the principles of fair chase. As a representative of the National Rifle Association (NRA) explained, "The NRA has always maintained that fair chase, being in the field with your firearm or bow, is an important element of hunting tradition. Sitting at your desk in front of your computer, clicking at a mouse, has nothing to do with hunting."
