input question: Question: "What is a drawback of fractal compression?" Context: "Today, nearly all commonly used video compression methods (e.g., those in standards approved by the ITU-T or ISO) apply a discrete cosine transform (DCT) for spatial redundancy reduction. The DCT that is widely used in this regard was introduced by N. Ahmed, T. Natarajan and K. R. Rao in 1974. Other methods, such as fractal compression, matching pursuit and the use of a discrete wavelet transform (DWT) have been the subject of some research, but are typically not used in practical products (except for the use of wavelet coding as still-image coders without motion compensation). Interest in fractal compression seems to be waning, due to recent theoretical analysis showing a comparative lack of effectiveness of such methods." Answer:???
output answer: typically not used in practical products

Question: "Are archaea prokaryotes or eukaryotes?" Context: "Once regarded as plants constituting the class Schizomycetes, bacteria are now classified as prokaryotes. Unlike cells of animals and other eukaryotes, bacterial cells do not contain a nucleus and rarely harbour membrane-bound organelles. Although the term bacteria traditionally included all prokaryotes, the scientific classification changed after the discovery in the 1990s that prokaryotes consist of two very different groups of organisms that evolved from an ancient common ancestor. These evolutionary domains are called Bacteria and Archaea." Answer:
----
Answer: prokaryotes

Q: Question: "What shows that Elizabeth is more than she appears to be?" Context: "Elizabeth has held many titles and honorary military positions throughout the Commonwealth, is Sovereign of many orders in her own countries, and has received honours and awards from around the world. In each of her realms she has a distinct title that follows a similar formula: Queen of Jamaica and her other realms and territories in Jamaica, Queen of Australia and her other realms and territories in Australia, etc. In the Channel Islands and Isle of Man, which are Crown dependencies rather than separate realms, she is known as Duke of Normandy and Lord of Mann, respectively. Additional styles include Defender of the Faith and Duke of Lancaster. When in conversation with the Queen, the practice is to initially address her as Your Majesty and thereafter as Ma'am." Answer:
A: military positions

Question: Question: "What did Nasser do when Egypt became burdened by financial problems?" Context: "During the presidential referendum in Egypt, Nasser was re-elected to a second term as UAR president and took his oath on 25 March 1965. He was the only candidate for the position, with virtually all of his political opponents forbidden by law from running for office, and his fellow party members reduced to mere followers. That same year, Nasser had the Muslim Brotherhood chief ideologue Sayyed Qutb imprisoned. Qutb was charged and found guilty by the court of plotting to assassinate Nasser, and was executed in 1966. Beginning in 1966, as Egypt's economy slowed and government debt became increasingly burdensome, Nasser began to ease state control over the private sector, encouraging state-owned bank loans to private business and introducing incentives to increase exports. During the 60's, the Egyptian economy went from sluggishness to the verge of collapse, the society became less free, and Nasser's appeal waned considerably." Answer:
Answer: encouraging state-owned bank loans to private business and introducing incentives to increase exports

Problem: Given the question: Question: "Who used videoconferencing later, internal corporate communication networks or schools?" Context: "While videoconferencing technology was initially used primarily within internal corporate communication networks, one of the first community service usages of the technology started in 1992 through a unique partnership with PictureTel and IBM Corporations which at the time were promoting a jointly developed desktop based videoconferencing product known as the PCS/1. Over the next 15 years, Project DIANE (Diversified Information and Assistance Network) grew to utilize a variety of videoconferencing platforms to create a multi-state cooperative public service and distance education network consisting of several hundred schools, neighborhood centers, libraries, science museums, zoos and parks, public assistance centers, and other community oriented organizations." Answer:
++++++++++++++++++++++++++++++++
The answer is:
schools
