Problem: The most reliable method for assessing pain in most humans is by asking a question: a person may report pain that cannot be detected by any known physiological measure. However, like infants (Latin infans meaning "unable to speak"), animals cannot answer questions about whether they feel pain; thus the defining criterion for pain in humans cannot be applied to them. Philosophers and scientists have responded to this difficulty in a variety of ways. Rene Descartes for example argued that animals lack consciousness and therefore do not experience pain and suffering in the way that humans do. Bernard Rollin of Colorado State University, the principal author of two U.S. federal laws regulating pain relief for animals, writes that researchers remained unsure into the 1980s as to whether animals experience pain, and that veterinarians trained in the U.S. before 1989 were simply taught to ignore animal pain. In his interactions with scientists and other veterinarians, he was regularly asked to "prove" that animals are conscious, and to provide "scientifically acceptable" grounds for claiming that they feel pain. Carbone writes that the view that animals feel pain differently is now a minority view. Academic reviews of the topic are more equivocal, noting that although the argument that animals have at least simple conscious thoughts and feelings has strong support, some critics continue to question how reliably animal mental states can be determined. The ability of invertebrate species of animals, such as insects, to feel pain and suffering is also unclear.

Problem: Silicon Alley, centered in Manhattan, has evolved into a metonym for the sphere encompassing the New York City metropolitan region's high technology industries involving the Internet, new media, telecommunications, digital media, software development, biotechnology, game design, financial technology ("fintech"), and other fields within information technology that are supported by its entrepreneurship ecosystem and venture capital investments. In the first half of 2015, Silicon Alley generated over US$3.7 billion in venture capital investment across a broad spectrum of high technology enterprises, most based in Manhattan, with others in Brooklyn, Queens, and elsewhere in the region. High technology startup companies and employment are growing in New York City and the region, bolstered by the city's position in North America as the leading Internet hub and telecommunications center, including its vicinity to several transatlantic fiber optic trunk lines, New York's intellectual capital, and its extensive outdoor wireless connectivity. Verizon Communications, headquartered at 140 West Street in Lower Manhattan, was at the final stages in 2014 of completing a US$3 billion fiberoptic telecommunications upgrade throughout New York City. As of 2014, New York City hosted 300,000 employees in the tech sector.

Problem: The original model Famicom featured two game controllers, both of which were hardwired to the back of the console. The second controller lacked the START and SELECT buttons, but featured a small microphone. Relatively few games made use of this feature. The earliest produced Famicom units initially had square A and B buttons. This was changed to the circular designs because of the square buttons being caught in the controller casing when pressed down and glitches within the hardware causing the system to freeze occasionally while playing a game.
What did the third Famicom controller have as a unique feature?
