Problem: MP3:

An MP3 file is made up of MP3 frames, which consist of a header and a data block. This sequence of frames is called an elementary stream. Due to the "byte reservoir", frames are not independent items and cannot usually be extracted on arbitrary frame boundaries. The MP3 Data blocks contain the (compressed) audio information in terms of frequencies and amplitudes. The diagram shows that the MP3 Header consists of a sync word, which is used to identify the beginning of a valid frame. This is followed by a bit indicating that this is the MPEG standard and two bits that indicate that layer 3 is used; hence MPEG-1 Audio Layer 3 or MP3. After this, the values will differ, depending on the MP3 file. ISO/IEC 11172-3 defines the range of values for each section of the header along with the specification of the header. Most MP3 files today contain ID3 metadata, which precedes or follows the MP3 frames, as noted in the diagram.

What is a sequence of MP3 frames called?

A: elementary stream

Problem: House music:

Influential gospel/R&B-influenced Aly-us released "Time Passes On" in 1993 (Strictly Rhythm), then later, "Follow Me" which received radio airplay as well as being played in clubs. Another U.S. hit which received radio play was the single "Time for the Perculator" by Cajmere, which became the prototype of ghetto house subgenre. Cajmere started the Cajual and Relief labels (amongst others). By the early 1990s artists such as Cajmere himself (under that name as well as Green Velvet and as producer for Dajae), DJ Sneak, Glenn Underground and others did many recordings. The 1990s saw new Chicago house artists emerge such as DJ Funk, who operates a Chicago house record label called Dance Mania. Ghetto house and acid house were other house music styles that were also started in Chicago.

Problem: Pesticide:

Though pesticide regulations differ from country to country, pesticides, and products on which they were used are traded across international borders. To deal with inconsistencies in regulations among countries, delegates to a conference of the United Nations Food and Agriculture Organization adopted an International Code of Conduct on the Distribution and Use of Pesticides in 1985 to create voluntary standards of pesticide regulation for different countries. The Code was updated in 1998 and 2002. The FAO claims that the code has raised awareness about pesticide hazards and decreased the number of countries without restrictions on pesticide use.

When were pesticides first able to be traded across international borders?

A: unanswerable

Problem: American Idol:

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.

In what season was the "Judges Save" introduced to give contestants a second chance?

A:
eight
