The MPEG-1 standard does not include a precise specification for an MP3 encoder, but does provide example psychoacoustic models, rate loop, and the like in the non-normative part of the original standard. At present, these suggested implementations are quite dated. Implementers of the standard were supposed to devise their own algorithms suitable for removing parts of the information from the audio input. As a result, there are many different MP3 encoders available, each producing files of differing quality. Comparisons are widely available, so it is easy for a prospective user of an encoder to research the best choice. An encoder that is proficient at encoding at higher bit rates (such as LAME) is not necessarily as good at lower bit rates.
Which standard does not include a specification for an MP3 encoder?
MPEG-1

In the dicotyledons, the bundles in the very young stem are arranged in an open ring, separating a central pith from an outer cortex. In each bundle, separating the xylem and phloem, is a layer of meristem or active formative tissue known as cambium. By the formation of a layer of cambium between the bundles (interfascicular cambium), a complete ring is formed, and a regular periodical increase in thickness results from the development of xylem on the inside and phloem on the outside. The soft phloem becomes crushed, but the hard wood persists and forms the bulk of the stem and branches of the woody perennial. Owing to differences in the character of the elements produced at the beginning and end of the season, the wood is marked out in transverse section into concentric rings, one for each season of growth, called annual rings.
What's another name for the concentric rings in trees?
annual rings

Bermuda was discovered in 1503 by Spanish explorer Juan de Bermúdez. It is mentioned in Legatio Babylonica, published in 1511 by historian Pedro Mártir de Anglería, and was also included on Spanish charts of that year. Both Spanish and Portuguese ships used the islands as a replenishment spot to take on fresh meat and water. Legends arose of spirits and devils, now thought to have stemmed from the calls of raucous birds (most likely the Bermuda petrel, or Cahow) and the loud noise heard at night from wild hogs. Combined with the frequent storm-wracked conditions and the dangerous reefs, the archipelago became known as the Isle of Devils. Neither Spain nor Portugal tried to settle it.
Crazy noises from indigenous animals, frequent storms and hazardous reefs earned the islands what name?
Isle of Devils
