In this task, you are given a question and a context passage. You have to answer the question based on the given passage.

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.

What is reduced by playback equipment?, Context: Due to recording mastering and manufacturing limitations, both high and low frequencies were removed from the first recorded signals by various formulae. With low frequencies, the stylus must swing a long way from side to side, requiring the groove to be wide, taking up more space and limiting the playing time of the record. At high frequencies, hiss, pops, and ticks are significant. These problems can be reduced by using equalization to an agreed standard. During recording the amplitude of low frequencies is reduced, thus reducing the groove width required, and the amplitude at high frequencies is increased. The playback equipment boosts bass and cuts treble so as to restore the tonal balance in the original signal; this also reduces the high frequency noise. Thus more music will fit on the record, and noise is reduced.

Accessories and games comes with?, Context: The NES Test Station's front features a Game Pak slot and connectors for testing various components (AC adapter, RF switch, Audio/Video cable, NES Control Deck, accessories and games), with a centrally-located selector knob to chose which component to test. The unit itself weighs approximately 11.7 pounds without a TV. It connects to a television via a combined A/V and RF Switch cable. By actuating the green button, a user can toggle between an A/V Cable or RF Switch connection. The television it is connected to (typically 11" to 14") is meant to be placed atop it.
