Problem: Background: The Naga people (pronounced [na:ga:]) are an ethnic group conglomerating of several tribes native to the North Eastern part of India and north-western Myanmar (Burma). The tribes have similar cultures and traditions, and form the majority ethnic group in the Indian state of Nagaland, with significant population in Manipur, Arunachal Pradesh and in Assam. The Naga speak various distinct Tibeto-Burman languages, including Anal, Angami, Ao, Chakhesang, Chang, Lotha, Mao (Emela), Maram, Phom, Pochuri, Poumai (Poula), Phom, Rengma, Rongmei (Ruangmei), Sangtam, Sumi, Tangkhul, Thangal and Zeme. In addition, the Naga have developed Nagamese Creole, which they use between various indigenous communities and villages, which each have their own dialect of language.
Context: Nagas have more language diversity than any other ethnic group or states in India. Naga people speak over 89 different languages and dialects, mostly unintelligible with each other. However, there are many similarities in between different languages spoken by them. Per Grierson's classification system, Naga languages can be grouped into Western, Central and Eastern Naga groups. The Western group includes among others Angami, Chokri, Khezha and Rengma. The Central Naga group includes Ao, and Lotha ; while Eastern group includes Konyak, Phom, Sangtam, Khiamniungan, Yimchunger and Chang tribes. The Sumi group originating in both central and western parts. In addition, there are Naga-Bodo group illustrated by Mikir language, and Kuki group of languages illustrated by Sopvama (also called Mao Naga) and Luppa languages. These mostly belong to the Tibeto-Burman language group of the Sino-Tibetan family of languages. Shafer came up with his own classification system for languages found in and around Nagaland.  The diversity of languages and traditions of the Nagas results most likely from the multiple cultural absorptions that occurred during their successive migrations. According to legend, before settling in the region, these groups moved over vast zones, and in the process, some clans were absorbed into one or more other tribes. Therefore, until recent times, absorptions were a source of many interclan conflicts.  In 1967, the Nagaland Assembly proclaimed English as the official language of Nagaland and it is the medium for education in Nagaland. Other than English, Nagamese, a creole language form of the Assamese language, is a widely spoken language. Every tribe has its own mother tongue but communicates with other tribes in Nagamese or English. However, English is the predominant spoken and written language in Nagaland.
Question: But does that mean English is the only official language?
Answer: Every tribe has its own mother tongue but communicates with other tribes in Nagamese or English. However, English is the predominant spoken and written language in Nagaland.

Background: Avenged Sevenfold (sometimes abbreviated as A7X) is an American heavy metal band from Huntington Beach, California, formed in 1999. The band's current lineup consists of lead vocalist M. Shadows, rhythm guitarist and backing vocalist Zacky Vengeance, lead guitarist and backing vocalist Synyster Gates, bassist and backing vocalist Johnny Christ, and drummer Brooks Wackerman. Avenged Sevenfold is known for its diverse rock sound and dramatic imagery in album covers and merchandise. Avenged Sevenfold emerged with a metalcore sound on the band's debut Sounding the Seventh Trumpet and continued this sound through their second album Waking the Fallen.
Context: The band's influences include Guns N' Roses, Iron Maiden, Megadeth, Pantera, Bad Religion, Dream Theater, Motorhead, Metallica, Black Sabbath, Led Zeppelin, The Rolling Stones, In Flames, At the Gates, Helloween, Queensryche, System of a Down, AC/DC, NOFX, Alice in Chains, Black Flag, Corrosion of Conformity, Suicidal Tendencies, Misfits, Slayer, The Vandals, Soundgarden, Rage Against the Machine, Korn, Slipknot, Deftones, Beastie Boys, Biohazard, Type O Negative, Anthrax and AFI.  The band has been categorized under many genres of heavy music. Mainly categorized as heavy metal, hard rock, progressive metal and metalcore, Avenged Sevenfold's music has evolved over most of the band's career. At first, the band's debut album Sounding the Seventh Trumpet consisted almost entirely of a metalcore sound; however, there were several deviations from this genre, most notably in "Streets", which shows a punk rock style, and "Warmness on the Soul", which is a piano ballad. On Waking the Fallen, the band displayed a metalcore style once more, but added more clean singing and leaned a bit more towards metal and bit less close to hardcore. In the band's DVD All Excess, producer Andrew Murdock explained this transition: "When I met the band after Sounding the Seventh Trumpet had come out before they had recorded Waking the Fallen, M. Shadows said to me 'This record is screaming. The record we want to make is going to be half-screaming half-singing. I don't want to scream anymore. And the record after that is going to be all singing'."  On City of Evil, Avenged Sevenfold's third album, the band chose to abandon the metalcore genre, using a more hard rock and heavy metal style. Avenged Sevenfold's self-titled album, however, has some experiments with other music genres than that from City of Evil, most notably in "Dear God", which shows a country style and "A Little Piece of Heaven", which is circled within the influence of Broadway show tunes, using primarily brass instruments and stringed orchestra to take over most of the role of the lead and rhythm guitar. Nightmare contains further deviations, including a piano ballad called "Fiction", progressive metal-oriented track "Save Me" and a heavy metal sound with extreme vocals and heavier instrumentation on "God Hates Us". The band's sixth studio album Hail to the King shows more of a classic metal sound and a riff-oriented approach. On their newest album The Stage, the band explores further into progressive metal, blending it with elements of thrash metal. In the past, Avenged Sevenfold has also been described as alternative metal, screamo, and pop punk metal.  The band has been criticized for "not being metal enough". Vocalist M. Shadows responded to this with, "we play music for the sake of music, not so that we can be labeled a metal band. That's like telling us we aren't punk enough. Who cares?" Avenged Sevenfold is one of the notable acts of the New Wave of American Heavy Metal.
