Question: Being Sicily's administrative capital, Palermo is a centre for much of the region's finance, tourism and commerce. The city currently hosts an international airport, and Palermo's economic growth over the years has brought the opening of many new businesses. The economy mainly relies on tourism and services, but also has commerce, shipbuilding and agriculture. The city, however, still has high unemployment levels, high corruption and a significant black market empire (Palermo being the home of the Sicilian Mafia). Even though the city still suffers from widespread corruption, inefficient bureaucracy and organized crime, the level of crime in Palermo's has gone down dramatically, unemployment has been decreasing and many new, profitable opportunities for growth (especially regarding tourism) have been introduced, making the city safer and better to live in.

Question: The third generation began including a 30-pin dock connector, allowing for FireWire or USB connectivity. This provided better compatibility with non-Apple machines, as most of them did not have FireWire ports at the time. Eventually Apple began shipping iPods with USB cables instead of FireWire, although the latter was available separately. As of the first-generation iPod Nano and the fifth-generation iPod Classic, Apple discontinued using FireWire for data transfer (while still allowing for use of FireWire to charge the device) in an attempt to reduce cost and form factor. As of the second-generation iPod Touch and the fourth-generation iPod Nano, FireWire charging ability has been removed. The second-, third-, and fourth-generation iPod Shuffle uses a single 3.5 mm minijack phone connector which acts as both a headphone jack and a data port for the dock.
Is there an answer to this question: What iPod feature allowed for USB connections with the device?

Answer: 30-pin dock connector

Question: Temporal measurement, chronometry, takes two distinct period forms: the calendar, a mathematical tool for organizing intervals of time, and the clock, a physical mechanism that counts the passage of time. In day-to-day life, the clock is consulted for periods less than a day whereas the calendar is consulted for periods longer than a day. Increasingly, personal electronic devices display both calendars and clocks simultaneously. The number (as on a clock dial or calendar) that marks the occurrence of a specified event as to hour or date is obtained by counting from a fiducial epocha central reference point.
Is there an answer to this question: What physical mechanism is used to count periods longer than a day?

Answer:
unanswerable
