Input: Read this: Bernanke explained that between 1996 and 2004, the U.S. current account deficit increased by $650 billion, from 1.5% to 5.8% of GDP. Financing these deficits required the country to borrow large sums from abroad, much of it from countries running trade surpluses. These were mainly the emerging economies in Asia and oil-exporting nations. The balance of payments identity requires that a country (such as the U.S.) running a current account deficit also have a capital account (investment) surplus of the same amount. Hence large and growing amounts of foreign funds (capital) flowed into the U.S. to finance its imports.
Question: What emerging economies did the U.S. borrow money from between 1996 and 2004 to finance its imports?

Output: Asia and oil-exporting nations


QUES: The Lord Mayor's official residence is 3 Elliot Terrace, located on the Hoe. Once a home of Waldorf and Nancy Astor, it was given by Lady Astor to the City of Plymouth as an official residence for future Lord Mayors and is also used today for civic hospitality, as lodgings for visiting dignitaries and High Court judges and it is also available to hire for private events. The Civic Centre municipal office building in Armada Way became a listed building in June 2007 because of its quality and period features, but has become the centre of a controversy as the council planned for its demolition estimating that it could cost £40m to refurbish it, resulting in possible job losses.

In what month and year did the Civic Centre municipal office building become a listed building?
What is the answer?
ANS: June 2007


QUES: After the Spanish in the 16th century, the first permanent European settlers of North Carolina were English colonists who migrated south from Virginia. The latter had grown rapidly and land was less available. Nathaniel Batts was documented as one of the first of these Virginian migrants. He settled south of the Chowan River and east of the Great Dismal Swamp in 1655. By 1663, this northeastern area of the Province of Carolina, known as the Albemarle Settlements, was undergoing full-scale English settlement. During the same period, the English monarch Charles II gave the province to the Lords Proprietors, a group of noblemen who had helped restore Charles to the throne in 1660. The new province of "Carolina" was named in honor and memory of King Charles I (Latin: Carolus). In 1712, North Carolina became a separate colony. Except for the Earl Granville holdings, it became a royal colony seventeen years later. A large revolt happened in the state in 1711 known as Cary's Rebellion.
After the Spanish, who were the first Europeans to settle North Carolina?

ANS: English colonists


Operating at normal power line frequencies, universal motors are often found in a range less than 1000 watts. Universal motors also formed the basis of the traditional railway traction motor in electric railways. In this application, the use of AC to power a motor originally designed to run on DC would lead to efficiency losses due to eddy current heating of their magnetic components, particularly the motor field pole-pieces that, for DC, would have used solid (un-laminated) iron and they are now rarely used.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What is the result of using AC power on a DC motor?
Ah, so.. efficiency losses


Question: Providing sufficient base drive current is a key problem in the use of bipolar transistors as switches. The transistor provides current gain, allowing a relatively large current in the collector to be switched by a much smaller current into the base terminal. The ratio of these currents varies depending on the type of transistor, and even for a particular type, varies depending on the collector current. In the example light-switch circuit shown, the resistor is chosen to provide enough base current to ensure the transistor will be saturated.
Try to answer this question if possible: What is a major problem with using bipolar transistors as switches?
Answer: Providing sufficient base drive current


Input: Read this: This new-found importance of naval aviation forced nations to create a number of carriers, in efforts to provide air superiority cover for every major fleet in order to ward off enemy aircraft. This extensive usage required the construction of several new 'light' carriers. Escort aircraft carriers, such as USS Bogue, were sometimes purpose-built, but most were converted from merchant ships as a stop-gap measure to provide anti-submarine air support for convoys and amphibious invasions. Following this concept, light aircraft carriers built by the US, such as USS Independence, represented a larger, more "militarized" version of the escort carrier. Although with similar complement to Escort carriers, they had the advantage of speed from their converted cruiser hulls. The UK 1942 Design Light Fleet Carrier was designed for building quickly by civilian shipyards and with an expected service life of about 3 years. They served the Royal Navy during the war and was the hull design chosen for nearly all aircraft carrier equipped navies after the war until the 1980s. Emergencies also spurred the creation or conversion of highly unconventional aircraft carriers. CAM ships, were cargo-carrying merchant ships that could launch (but not retrieve) a single fighter aircraft from a catapult to defend the convoy from long range German aircraft.
Question: What type of aircraft carrier was the USS Bogue?

Output:
Escort
