Problem: Background: Journey is an American rock band that formed in San Francisco in 1973, composed of former members of Santana and Frumious Bandersnatch. The band has gone through several phases; its strongest commercial success occurred between 1978 and 1987. During that period, the band released a series of hit songs, including "Don't Stop Believin'" (1981), which in 2009 became the top-selling track in iTunes history among songs not released in the 21st century. Its parent studio album, Escape, the band's eighth and most successful, reached No. 1 on the Billboard 200 and yielded another of their most popular singles, "Open Arms".
Context: Journey's album sales did not improve and Columbia Records requested that they change their musical style and add a frontman, with whom keyboardist Gregg Rolie could share lead vocal duties. The band hired Robert Fleischman and transitioned to a more popular style, akin to that of Foreigner and Boston. Journey went on tour with Fleischman in 1977 and together the new incarnation of the band wrote the hit "Wheel in the Sky"; however, management differences resulted in Fleischman leaving within the year.  In late 1977, Journey hired Steve Perry as their new lead singer. Herbie Herbert, the band's manager, also hired Roy Thomas Baker as a producer to add a layered sound approach as Baker had done with his previous band, Queen. With their new lead singer and talented new producer, Journey released their fourth album, Infinity (1978). This album set Journey on their road to stardom with their first RIAA-certified platinum album. This album, with their hit song "Wheel in the Sky" (#57 U.S.), set Journey on a new path with a more mainstream sound to make their highest chart success to date.  In late 1978, manager Herbie Herbert fired drummer Aynsley Dunbar, who joined Bay Area rivals Jefferson Starship shortly thereafter. He was replaced by Berklee-trained jazz drummer Steve Smith. Perry, Schon, Rolie, Smith and Valory recorded Evolution (1979), which gave the band their first Billboard Hot 100 Top 20 single, "Lovin', Touchin', Squeezin'" (#16); and Departure (1980), which reached No. 8 on the album charts.  Journey's newfound success brought the band an almost entirely new fan base. During the 1980 Departure world tour, the band recorded a live album, Captured.  Keyboardist Gregg Rolie then left the band, the second time in his career he left a successful act. Keyboardist Stevie "Keys" Roseman was brought in to record the lone studio track for Captured, "The Party's Over (Hopelessly in Love)," but Rolie recommended pianist Jonathan Cain of The Babys as the permanent replacement. With Cain's replacement of Rolie's Hammond B-3 organ with his own synthesizers, the band was poised for a new decade in which they would achieve their greatest musical success.
Question: did they do so?
Answer: Captured, "The Party's Over (Hopelessly in Love)," but Rolie recommended pianist Jonathan Cain of The Babys as the permanent

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.
