Problem: Please answer a question about the following article about Gramophone record:
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.
What is done during recordings to help reduce unwanted sounds?
A: amplitude of low frequencies is reduced
Problem: Please answer a question about the following article about Norfolk Island:
As early as 1794, Lieutenant-Governor of New South Wales Francis Grose suggested its closure as a penal settlement, as it was too remote and difficult for shipping and too costly to maintain. The first group of people left in February 1805, and by 1808 only about 200 remained, forming a small settlement until the remnants were removed in 1813. A small party remained to slaughter stock and destroy all buildings, so that there would be no inducement for anyone, especially from other European powers, to visit and lay claim to the place. From 15 February 1814 to 6 June 1825 the island was abandoned.
When did Lieutenant-Governor of New South Wales Francis Grose start suggesting Norfolk Island be closed as a penal settlement?
A: 1794
Problem: Please answer a question about the following article about Cork (city):
The city is also home to the Heineken Brewery that brews Murphy's Irish Stout and the nearby Beamish and Crawford brewery (taken over by Heineken in 2008) which have been in the city for generations. 45% of the world's Tic Tac sweets are manufactured at the city's Ferrero factory. For many years, Cork was the home to Ford Motor Company, which manufactured cars in the docklands area before the plant was closed in 1984. Henry Ford's grandfather was from West Cork, which was one of the main reasons for opening up the manufacturing facility in Cork. But technology has replaced the old manufacturing businesses of the 1970s and 1980s, with people now working in the many I.T. centres of the city such as Amazon.com, the online retailer, which has set up in Cork Airport Business Park.
Cork is home to which internationally famous brewery?
A: Heineken
Problem: Please answer a question about the following article about Hyderabad:
The Kakatiya dynasty was reduced to a vassal of the Khilji dynasty in 1310 after its defeat by Sultan Alauddin Khilji of the Delhi Sultanate. This lasted until 1321, when the Kakatiya dynasty was annexed by Malik Kafur, Allaudin Khilji's general. During this period, Alauddin Khilji took the Koh-i-Noor diamond, which is said to have been mined from the Kollur Mines of Golkonda, to Delhi. Muhammad bin Tughluq succeeded to the Delhi sultanate in 1325, bringing Warangal under the rule of the Tughlaq dynasty until 1347 when Ala-ud-Din Bahman Shah, a governor under bin Tughluq, rebelled against Delhi and established the Bahmani Sultanate in the Deccan Plateau, with Gulbarga, 200 km (124 mi) west of Hyderabad, as its capital. The Bahmani kings ruled the region until 1518 and were the first independent Muslim rulers of the Deccan.
In what year did Muhammad bin Tughluq succeed the Delhi sultanate?
A:
1325
