Problem: Please answer a question about the following article about Data compression:
In lossy audio compression, methods of psychoacoustics are used to remove non-audible (or less audible) components of the audio signal. Compression of human speech is often performed with even more specialized techniques; speech coding, or voice coding, is sometimes distinguished as a separate discipline from audio compression. Different audio and speech compression standards are listed under audio coding formats. Voice compression is used in internet telephony, for example, audio compression is used for CD ripping and is decoded by the audio players.
What is used for CD ripping?
A: audio compression
Problem: Please answer a question about the following article about Middle Ages:
The importance of infantry and light cavalry began to decline during the early Carolingian period, with a growing dominance of elite heavy cavalry. The use of militia-type levies of the free population declined over the Carolingian period. Although much of the Carolingian armies were mounted, a large proportion during the early period appear to have been mounted infantry, rather than true cavalry. One exception was Anglo-Saxon England, where the armies were still composed of regional levies, known as the fyrd, which were led by the local elites. In military technology, one of the main changes was the return of the crossbow, which had been known in Roman times and reappeared as a military weapon during the last part of the Early Middle Ages. Another change was the introduction of the stirrup, which increased the effectiveness of cavalry as shock troops. A technological advance that had implications beyond the military was the horseshoe, which allowed horses to be used in rocky terrain.
Along with the horseshoe, what invention important for cavalry emerged in this period?
A: the stirrup
Problem: Please answer a question about the following article about Affirmative action in the United States:
Affirmative action in the United States tends to focus on issues such as education and employment, specifically granting special consideration to racial minorities, Native Americans, and women who have been historically excluded groups in America. Reports have shown that minorities and women have faced discrimination in schools and businesses for many years and this discrimination produced unfair advantages for whites and males in education and employment. The impetus toward affirmative action is redressing the disadvantages associated with past and present discrimination. Further impetus is a desire to ensure public institutions, such as universities, hospitals, and police forces, are more representative of the populations they serve.
Affirmative action does not only attempt to remove disadvantages, but also to ensure what about the number of people in a field?
A: are more representative of the populations they serve
Problem: Please answer a question about the following article about Pub:
The Licensing Act 2003, which came into force on 24 November 2005, consolidated the many laws into a single Act. This allowed pubs in England and Wales to apply to the local council for the opening hours of their choice. It was argued that this would end the concentration of violence around 11.30 pm, when people had to leave the pub, making policing easier. In practice, alcohol-related hospital admissions rose following the change in the law, with alcohol involved in 207,800 admissions in 2006/7. Critics claimed that these laws would lead to "24-hour drinking". By the time the law came into effect, 60,326 establishments had applied for longer hours and 1,121 had applied for a licence to sell alcohol 24 hours a day. However nine months later many pubs had not changed their hours, although some stayed open longer at the weekend, but rarely beyond 1:00 am.
How many pubs applied to be allowed to sell alcohol 24 hours a day?
A:
1,121
