In this task, you're given passages that contain mentions of names of people, places, or things. Some of these mentions refer to the same person, place, or thing. Your job is to write questions that evaluate one's understanding of such references. Good questions are expected to link pronouns (she, her, him, his, their, etc.) or other mentions to people, places, or things to which they may refer. Do not ask questions that can be answered correctly without understanding the paragraph or having multiple answers. Avoid questions that do not link phrases referring to the same entity. For each of your questions, the answer should be one or more phrases in the paragraph, and it should be unambiguous.

[Q]: Passage: Sergeant First Class Buck McGriff and Sergeant First Class Albaby Perkins are two joint services Criminal Investigation Division agents on duty in war torn Saigon. When a prostitute is found murdered they discover that the prime suspects are high ranking U.S. Army officers. As they investigate they find that there have been a string of at least six murders in the last year, but the previous inquiry was shut down from higher up the chain of command. Investigations lead them to Colonel Dexter Armstrong, but Armstrong rules himself out of inquiries by committing suicide. With the help of a French nun Sister Nicole and their non-commissioned officer in charge, Master Sergeant Dix, they finally close in on their target. As their investigation leads them closer and closer to the murderer, they find their lives are in danger and they end up nearly being sent home. The movie ends with an unexpected twist when they rule out all their suspects by conducting an interview in a Viet Cong tunnel base, and their NCO is the killer.
[A]: What is the full name of the characters who learn of a string of six murders?

[Q]: Passage: Holst made some recordings, conducting his own music. For the Columbia company he recorded Beni Mora, the Marching Song and the complete Planets with the London Symphony Orchestra (LSO) in 1922, using the acoustic process. The limitations of early recording prevented the gradual fade-out of women's voices at the end of "Neptune", and the lower strings had to be replaced by a tuba to obtain an effective bass sound. With an anonymous string orchestra Holst recorded the St Paul's Suite and Country Song in 1925. Columbia's main rival, HMV, issued recordings of some of the same repertoire, with an unnamed orchestra conducted by Albert Coates. When electrical recording came in, with dramatically improved recording quality, Holst and the LSO re-recorded The Planets for Columbia in 1926.In the early LP era little of Holst's music was available on disc. Only six of his works are listed in the 1955 issue of The Record Guide: The Planets (recordings under Boult on HMV and Nixa, and another under Sir Malcolm Sargent on Decca); the Perfect Fool ballet music; the St Paul's Suite; and three short choral pieces. In the stereo LP and CD eras numerous recordings of The Planets were issued, performed by orchestras and conductors from round the world. By the early years of the 21st century most of the major and many of the minor orchestral and choral works had been issued on disc. The 2008 issue of The Penguin Guide to Recorded Classical Music contained seven pages of listings of Holst's works on CD. Of the operas, Savitri, The Wandering Scholar, and At the Boar's Head have been recorded.
[A]: What is the last name of the person of whose works only six are listed in the 1955 issue of The Record Guide?

[Q]: Passage: Ethiopian historians such as Taddesse Tamrat (19352013) and Sergew Hable Sellassie have argued that modern Ethiopian studies were an invention of the 17th century and originated in Europe. Tamrat considered Carlo Conti Rossini's 1928 Storia d'Etiopia a groundbreaking work in Ethiopian studies. The philosopher Messay Kebede likewise acknowledged the genuine contributions of Western scholars to the understanding of Ethiopia's past. But he also criticized the perceived scientific and institutional bias that he found to be pervasive in Ethiopian-, African-, and Western-made historiographies on Ethiopia. Specifically, Kebede took umbrage at E. A. Wallis Budge's translation of the Kebra Nagast, arguing that Budge had assigned a South Arabian origin to the Queen of Sheba although the Kebra Nagast itself did not indicate such a provenience for this fabled ruler. According to Kebede, a South Arabian extraction was contradicted by biblical exegetes and testimonies from ancient historians, which instead indicated that the Queen was of African origin. Additionally, he chided Budge and Ullendorff for their postulation that the Aksumite civilization was founded by Semitic immigrants from South Arabia. Kebede argued that there is little physical difference between the Semitic-speaking populations in Ethiopia and neighboring Cushitic-speaking groups to validate the notion that the former groups were essentially descendants of South Arabian settlers, with a separate ancestral origin from other local Afroasiatic-speaking populations. He also observed that these Afroasiatic-speaking populations were heterogeneous, having interbred with each other and also assimilated alien elements of both uncertain extraction and negroid origin.
[A]:
What are the full names of the two Ethiopian historians that have argued that modern Ethiopian studies were an invention the the 17th century?
