Unlike the Baltimore dialect, however, the Philadelphia accent also shares many similarities with the New York accent. Thanks to over a century of linguistics data collected by researchers at the University of Pennsylvania, the Philadelphia dialect under sociolinguist William Labov has been one of the best-studied forms of American English.[f]

Problem: Given the question: Extract the answer to the question from the following context. Question: Which of the following does not require large amounts of power: motors, USB cables or lamps? Context: Some USB devices require more power than is permitted by the specifications for a single port. This is common for external hard and optical disc drives, and generally for devices with motors or lamps. Such devices can use an external power supply, which is allowed by the standard, or use a dual-input USB cable, one input of which is used for power and data transfer, the other solely for power, which makes the device a non-standard USB device. Some USB ports and external hubs can, in practice, supply more power to USB devices than required by the specification but a standard-compliant device may not depend on this.

USB cable

Problem: Given the question: Extract the answer to the question from the following context. Question: Which school was founded thirty-seven years after RPI? Context: Polytechnic Institutes are technological universities, many dating back to the mid-19th century. A handful of world-renowned Elite American universities include the phrases "Institute of Technology", "Polytechnic Institute", "Polytechnic University", or similar phrasing in their names; these are generally research-intensive universities with a focus on engineering, science and technology. The earliest and most famous of these institutions are, respectively, Rensselaer Polytechnic Institute (RPI, 1824), New York University Tandon School of Engineering (1854) and the Massachusetts Institute of Technology (MIT, 1861). Conversely, schools dubbed "technical colleges" or "technical institutes" generally provide post-secondary training in technical and mechanical fields, focusing on training vocational skills primarily at a community college levelparallel and sometimes equivalent to the first two years at a bachelor's degree-granting institution.
