QUES: 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.
What iPod feature allowed for USB connections with the device?

ANS: 30-pin dock connector

QUES: Until the 20th century, there was no clear record of the number of Venezuelans who emigrated to the United States. Between the 18th and early 19th centuries, there were many European immigrants who went to Venezuela, only to later migrate to the United States along with their children and grandchildren who born and/or grew up in Venezuela speaking Spanish. From 1910 to 1930, it is estimated that over 4,000 South Americans each year emigrated to the United States; however, there are few specific figures indicating these statistics. Many Venezuelans settled in the United States with hopes of receiving a better education, only to remain in there following graduation. They are frequently joined by relatives. However, since the early 1980s, the reasons for Venezuelan emigration have changed to include hopes of earning a higher salary and due to the economic fluctuations in Venezuela which also promoted an important migration of Venezuelan professionals to the US.
Do Venezuelans still come to America for the same reasons as they did before?

ANS: since the early 1980s, the reasons for Venezuelan emigration have changed to include hopes of earning a higher salary

QUES: Von Neumann's ability to instantaneously perform complex operations in his head stunned other mathematicians. Eugene Wigner wrote that, seeing von Neumann's mind at work, "one had the impression of a perfect instrument whose gears were machined to mesh accurately to a thousandth of an inch." Paul Halmos states that "von Neumann's speed was awe-inspiring." Israel Halperin said: "Keeping up with him was ... impossible. The feeling was you were on a tricycle chasing a racing car." Edward Teller wrote that von Neumann effortlessly outdid anybody he ever met, and said "I never could keep up with him". Teller also said "von Neumann would carry on a conversation with my 3-year-old son, and the two of them would talk as equals, and I sometimes wondered if he used the same principle when he talked to the rest of us. Most people avoid thinking if they can, some of us are addicted to thinking, but von Neumann actually enjoyed thinking, maybe even to the exclusion of everything else."
How quickly was von Neumann able to complete math in his head?

ANS: stunned other mathematicians

QUES: In addition to the above, Greece is also to start oil and gas exploration in other locations in the Ionian Sea, as well as the Libyan Sea, within the Greek exclusive economic zone, south of Crete. The Ministry of the Environment, Energy and Climate Change announced that there was interest from various countries (including Norway and the United States) in exploration, and the first results regarding the amount of oil and gas in these locations were expected in the summer of 2012. In November 2012, a report published by Deutsche Bank estimated the value of natural gas reserves south of Crete at 427 billion.
What did the Deutsche Bank estimate the value of the reserves to become in years ahead?
