 Passage 2:Habesha peoples: /Habesha/ or /Abesha/ ((rarely Habeshat: ), or rarely used exonyms like "Abyssinian people," "Aithiops: ," "Athtiu-abu: Ancient Egyptian: Āthtiu-ábu ~ 'robbers of hearts' ~," or "al-Ḥabaš/al-Ḥabaši (al-Habash/al-Habashi): Mehri in Arabic script: الهباش / الحبشي‎ ~ ‘incense gatherers’ ~”. Habesha () ) is a common pan-ethnic and meta-ethnic term used to refer to both Ethiopians and Eritreans as a whole. Certain definitions considered the Ethiosemitic-speaking and Agwa-speaking Cushitic peoples inhabiting the highlands of Ethiopia and Eritrea as the core ethnic groups that historically constituted the pan-ethnic group Habesha peoples, while this notion is only partially accepted. They historically include a linguistically, culturally and ancestrally related ethnic groups, conservatively-speaking mostly from the Ethiopian Highlands, but in a broader sense included other Ethiopian-Eritrean ethnic groups as well. Members' cultural, linguistic, and in certain cases, ancestral origins trace back to the Kingdom of Dʿmt, the Kingdom of Aksum, among other kingdoms that either preceded or constituted the Ethiopian Empire in the Horn of Africa. Some Scholars have classified the Tigrayans and the Amhara as Abyssinians proper under an ultra-neo-conservative theory postulated by a few scholars and political parties but not widely accepted by the general public or by most indigenous scholars of the region.
 Passage 3:The year 2007 saw for the first time a racially-tailored Guide: the Food Guide for First Nations, Inuit and Métis people was born. For all other Canadians, the name evolved to Eating Well with Canada's Food Guide. The recognition of the multi-cultural nature of Canada meant that the food guide needed to balloon, to six pages in a fold-out pamphlet as opposed to the recto-verso poster format that had been used in days of yore. Obesity was recognised as a dietary problem. The Milk Products group became known as the Milk and Alternatives group, as "fortified soy beverage" was officially introduced to accommodate "non-milk drinkers". A guidance to reduce consumption of trans fats and replace saturated fats with unsaturated fats was identified. Instead of the cod-liver oil of days gone by, Canadians over 50 years of age were invited to consume vitamin D dietary supplements in order to normalise the method of ingestion by pharmaceutical pill. The choice of healthy foods was linked to the food label. A more "ethnically diverse" range of foods was depicted in order to reflect the European detonation of Canada. Nine age and sex groups were identified for specific recommendations but the LGBTQ lobby was still in its infancy and so no mention of them was made. "Three Advisory Groups provided guidance and advice throughout the revision process – the DRI Expert Advisory Committee, an Interdepartmental Working Group and the Food Guide Advisory Committee". An "extensive consultation with a range of stakeholders regarding the 1992 Food Guide" was duly noted. The Dietary Reference Intake (DRI) tool from the American Institute of Medicine was introduced to the Canadian taxpayer, as the NAFTA made its presence felt on the dinner table.

[EX Q]: Question: Which of the schools where Chandrasekhar studied was established first? Passage 1:The Australian Government challenged the High Court's decision in the Boilermaker's case and obtained special leave to appeal to the Privy Council on 1 June 1956. The Australian parliament did not wait for the outcome of the appeal, passing the Conciliation and Arbitration Act which received assent on 30 June 1956.. The court was formally established on 15 August 1956 and then Attorney-General John Spicer was appointed the first, and as it transpired, only, Chief Judge. Judges of the Commonwealth Court of Conciliation and Arbitration had previously been appointed to act in various courts, This practice continued with appointments to the supreme courts of the Australian Capital Territory, Christmas, Cocos (Keeling), & Norfolk Islands. Sir John Spicer was appointed to the first Royal Commission into the collision between HMAS Melbourne and HMAS Voyager, and inquiries into the aviation crashes of TAA Flight 538 (1960), Ansett-ANA Flight 325 (1961) and Ansett-ANA Flight 149 (1966). Judges were also appointed to committees to review legislation and report to parliament, such as the appointment of Sir John Spicer to the Copyright Law Review Committee, and John Kerr to the Commonwealth Administrative Review Committee. The Copyright Law Review Committee subsequently recommended the appointment of the Copyright Tribunal and Sir John Spicer was appointed as its president. When the Australian Parliament passed the Trade Practices Act in 1965, the Commonwealth Industrial Court was given power to enforce orders of the Trade Practices Tribunal, and Sir Richard Eggleston was appointed the first president of the Trade Practices Tribunal.

 Passage 3:Chakotay is a fictional character who appears in each of the seven seasons of the American science fiction television series . Portrayed by Robert Beltran, he is First Officer aboard the Starfleet starship USS Voyager. The character was suggested at an early stage of the development of the series. He is the first Native American main character in the Star Trek franchise. This was a deliberate move by the producers of the series, who sought to provide an inspiration as with Uhura in  for African Americans. To develop the character, the producers sought the assistance of Jamake Highwater. Despite first being named as a Sioux, and later a Hopi, Chakotay was given no tribal affiliation at the start of the series, something that was later resolved in the episode "".

[EX Q]: Question: Which of the three films that the "Ren-a-yank" duo worked on had the highest box office? Passage 1:Bishop continued to act on film, TV and radio, usually in British and other European productions, and was a frequent guest at science fiction conventions. Bishop and fellow Anderson actor Shane Rimmer (a Canadian actor who often worked in the UK) often joked about how often their professional paths crossed and termed themselves "Rent-a-yank". They appeared together as NASA operatives in the opening of You Only Live Twice and as United States Navy sailors in The Bedford Incident, as well as the 1983 film of the Harold Robbins novel The Lonely Lady. In 1989, Bishop was reunited with Rimmer and another Anderson actor, Matt Zimmerman, in the BBC Radio 4 adaptation of Sir Arthur Conan Doyle's A Study In Scarlet. Bishop and Rimmer also toured together in theatre shows including Death of a Salesman in the 1990s and also appeared in the BBC drama-documentary Hiroshima (2005), one of Bishop's last TV projects.
 Passage 2:The game began shortly after 4 p.m. with Greg Maddux pitching for Atlanta and Masato Yoshii starting for the Mets. The Mets took an early 2–0 lead in the bottom of the first inning as John Olerud hit his second home run in as many days with Rickey Henderson on first. The lead lasted into the fourth inning, when Atlanta struck back with consecutive doubles by Bret Boone and Chipper Jones, eventually knotting the score at 2–2 when Brian Jordan singled home Jones. Mets Manager Bobby Valentine was immediately prompted to remove Yoshii from the game in favor of Orel Hershiser, which began a run on pitching changes that resulted in the Mets emptying their bullpen by game's end, relying on starter Kenny Rogers and rookie Octavio Dotel for key innings, and might have gone to Game 4's starter Rick Reed had the game progressed past the fifteenth inning. In all, the Mets used a postseason record nine pitchers in this game.
 Passage 3:After a short stay in Europe in 1863, Munzinger returned to the north and north-east borderlands of Ethiopia. In 1865 Munzinger managed the British consulate along the border of Ethiopia, but remained in Massawa, after the 1868 British invasion of Ethiopia, where he became the French consul. There, according to Augustus B. Wylde, he married a woman of Hamasien and convinced one of the local warlords, Wolde Mikael, to cede the province of Hamasien to France. Munzinger sailed to France, and by early 1870 had an expedition ready at Toulon to sail to Massawa when the Franco-Prussian War broke out, and French resources were diverted to this higher priority, whereupon he left the service of the French. In July of that year he was sent to Aden, where he joined Captain S.B. Miles on an expedition into the interior of the southern Arabian peninsula. He then left the French and entered the service of the Egyptian government of Khedive Ismail, serving as governor of the Keren region and Massawa (modern-day Eritrea). Once he reached his command, his first act was to place the Bogos once again under Egyptian rule.
