A glacier (US /ˈɡleɪʃər/ or UK /ˈɡlæsiə/) is a persistent body of dense ice that is constantly moving under its own weight; it forms where the accumulation of snow exceeds its ablation (melting and sublimation) over many years, often centuries. Glaciers slowly deform and flow due to stresses induced by their weight, creating crevasses, seracs, and other distinguishing features. They also abrade rock and debris from their substrate to create landforms such as cirques and moraines. Glaciers form only on land and are distinct from the much thinner sea ice and lake ice that form on the surface of bodies of water.
Which types of ice form on a body of water's surface?
sea ice and lake ice


Input: Data compression
To determine what information in an audio signal is perceptually irrelevant, most lossy compression algorithms use transforms such as the modified discrete cosine transform (MDCT) to convert time domain sampled waveforms into a transform domain. Once transformed, typically into the frequency domain, component frequencies can be allocated bits according to how audible they are. Audibility of spectral components calculated using the absolute threshold of hearing and the principles of simultaneous masking—the phenomenon wherein a signal is masked by another signal separated by frequency—and, in some cases, temporal masking—where a signal is masked by another signal separated by time. Equal-loudness contours may also be used to weight the perceptual importance of components. Models of the human ear-brain combination incorporating such effects are often called psychoacoustic models.

What may be used to weight the importance of components?
Output: Equal-loudness contours


Input: Article: Norfolk Island is located in the South Pacific Ocean, east of the Australian mainland. Norfolk Island is the main island of the island group the territory encompasses and is located at 29°02′S 167°57′E﻿ / ﻿29.033°S 167.950°E﻿ / -29.033; 167.950. It has an area of 34.6 square kilometres (13.4 sq mi), with no large-scale internal bodies of water and 32 km (20 mi) of coastline. The island's highest point is Mount Bates (319 metres (1,047 feet) above sea level), located in the northwest quadrant of the island. The majority of the terrain is suitable for farming and other agricultural uses. Phillip Island, the second largest island of the territory, is located at 29°07′S 167°57′E﻿ / ﻿29.117°S 167.950°E﻿ / -29.117; 167.950, seven kilometres (4.3 miles) south of the main island.

Now answer this question: What is the name of the second largest island of the territory of Norfolk Island?

Output: Phillip Island


Article: Seattle is home to the University of Washington, as well as the institution's professional and continuing education unit, the University of Washington Educational Outreach. A study by Newsweek International in 2006 cited the University of Washington as the twenty-second best university in the world. Seattle also has a number of smaller private universities including Seattle University and Seattle Pacific University, the former a Jesuit Catholic institution, the latter Free Methodist; universities aimed at the working adult, like City University and Antioch University; colleges within the Seattle Colleges District system, comprising North, Central, and South; seminaries, including Western Seminary and a number of arts colleges, such as Cornish College of the Arts, Pratt Fine Arts Center, and The Art Institute of Seattle. In 2001, Time magazine selected Seattle Central Community College as community college of the year, stating the school "pushes diverse students to work together in small teams".

Question: Where can a student find to study art in Seattle?
Ans: arts colleges


Here is a question about this article: House also had an influence of relaying political messages to people who were considered to be outcasts of society. The music appealed to those who didn't fit into mainstream American society and was especially celebrated by many black males. Frankie Knuckles once said that the Warehouse club in Chicago was like "church for people who have fallen from grace" The house producer Marshall Jefferson compared it to "old-time religion in the way that people just get happy and screamin'". Deep house was similar to many of the messages of freedom for the black community.
What is the answer to this question: Who was a famous house producer?
****
So... Marshall Jefferson


Article: The most popular contestants are usually not revealed in the results show. Instead, typically the three contestants (two in later rounds) who received the lowest number of votes are called to the center of the stage. One of these three is usually sent to safety; however the two remaining are not necessarily the bottom two. The contestant with the fewest votes is then revealed and eliminated from the competition. A montage of the eliminated contestant's time on the show is played and they give their final performance. However, in season six, during the series' first ever Idol Gives Back episode, no contestant was eliminated, but on the following week, two were sent home. Moreover, starting in season eight, the judges may overturn viewers' decision with a "Judges' Save" if they unanimously agree to. "The save" can only be used once, and only up through the top five. In the eighth, ninth, tenth, and fourteenth seasons, a double elimination then took place in the week following the activation of the save, but in the eleventh and thirteenth seasons, a regular single elimination took place. The save was not activated in the twelfth season and consequently, a non-elimination took place in the week after its expiration with the votes then carrying over into the following week.

Question: How many time can the judges save be used each season?
Ans:
once
