Question: How are the rural medical centers using the highly useful technology of videoconferencing?, Context: Videoconferencing is a highly useful technology for real-time telemedicine and telenursing applications, such as diagnosis, consulting, transmission of medical images, etc... With videoconferencing, patients may contact nurses and physicians in emergency or routine situations; physicians and other paramedical professionals can discuss cases across large distances. Rural areas can use this technology for diagnostic purposes, thus saving lives and making more efficient use of health care money. For example, a rural medical center in Ohio, United States, used videoconferencing to successfully cut the number of transfers of sick infants to a hospital 70 miles (110 km) away. This had previously cost nearly $10,000 per transfer.

Answer: cut the number of transfers of sick infants to a hospital


Question: Why did using the method Bach didn't use, gain traction?, Context: The theories surrounding equal temperament began to be put in wider practice, especially as it enabled a wider range of chromatic possibilities in hard-to-tune keyboard instruments. Although Bach did not use equal temperament, as a modern piano is generally tuned, changes in the temperaments from the meantone system, common at the time, to various temperaments that made modulation between all keys musically acceptable, made possible Bach's Well-Tempered Clavier.

Answer: it enabled a wider range of chromatic possibilities in hard-to-tune keyboard instruments


Question: Oracle and Hewlett Packard preformed better than Dell in what areas?, 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 market—prevented 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.

Answer:
vertically integrated stacks
