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.

Input: Consider Input: Passage: Following the end of the Second World War, the East German side of the border was guarded initially by the Border Troops (Pogranichnyie Voiska) of the Soviet NKVD (later the KGB). They were supplemented from 1946 by a locally recruited paramilitary force, the German Border Police (Deutsche Grenzpolizei or DGP), before the Soviets handed over full control of the border to the East Germans in 1955/56. In 1961, the DGP was converted into a military force within the National People's Army (Nationale Volksarmee, NVA). The newly renamed Border Troops of the GDR (Grenztruppen der DDR, commonly nicknamed the Grenzer) came under the NVA's Border Command or Grenzkommando. They were responsible for securing and defending the borders with West Germany, Czechoslovakia, Poland, the Baltic Sea and West Berlin. At their peak, the Grenztruppen had up to 50,000 personnel.Around half of the Grenztruppen were conscripts, a lower proportion than in other branches of the East German armed forces. Many potential recruits were screened out as potentially unreliable; for instance, actively religious individuals or those with close relatives in West Germany. They were all subjected to close scrutiny to assure their political reliability and were given intensive ideological indoctrination.A special unit of the Stasi secret police worked covertly within the Grenztruppen, posing as regular border guards, between 1968 and 1985, to weed out potential defectors. One in ten officers and one in thirty enlisted men were said to have been recruited by the Stasi as informers. The Stasi regularly interviewed and maintained files on every guard. Stasi operatives were directly responsible for some aspects of security; passport control stations at crossings were manned by Stasi officers wearing Grenztruppen uniforms.The Grenztruppen were closely watched to ensure that they could not take advantage of their inside knowledge to escape across the border. Patrols, watchtowers and observation posts were always manned by two or three guards at a time. They were not allowed to go out of each other's sight in any circumstances. If a guard attempted to escape, his colleagues were under instructions to shoot him without hesitation or prior warning; 2,500 did escape to the West, 5,500 more were caught and imprisoned for up to five years, and a number were shot and killed or injured in the attempt.
The work of the guards involved carrying out repair work on the defences, monitoring the zone from watchtowers and bunkers and patrolling the line several times a day. Border Reconnaissance (Grenzaufklarungszug or GAK) soldiers, an elite reconnaissance force, carried out patrols and intelligence-gathering on the western side of the fence. Western visitors to the border were routinely photographed by the GAKs, who also oversaw work detachments maintaining the fence. The workers would be covered by machine guns to discourage them from attempting to escape.

Output: What is the nickname of the group that screened out many potential recruits?

Input: Consider Input: Passage: While diving off the Miami coast seeking one of the eleven fabled Spanish Galleons sunk in 1591, private investigator Tony Rome discovers a dead woman, her feet encased in cement, at the bottom of the ocean.
Rome reports this to Lieutenant Dave Santini and thinks nothing more of the incident, until Waldo Gronski hires him to find a missing woman, Sandra Lomax. Gronski has little in the way of affluence, so he allows Rome to pawn his watch to retain his services.
After investigating the local hotspots and picking up on a few names, Rome soon comes across Kit Forrester, whose party Sandra Lomax was supposed to have attended. Rome's talking to Forrester raises the ire of racketeer Al Mungar, a supposedly reformed gangster who looks after Kit's interests.
Thinking there may be a connection between Lomax, Forrester and Mungar, Rome starts probing into their backgrounds and begins a romantic relationship with Kit. With both cops and crooks chasing him and the omnipresent Gronski breathing down his neck, Rome finds himself deep in a case which provides few answers.

Output: What is the first name of the man that pawns the watch of the person looking for the missing woman?

Input: Consider Input: Passage: Sydney Morning Herald commentator Bernard Zuel described Dream Days at the Hotel Existence as Powderfinger's first dull album, noting that on numerous songs "It promises to become exciting but never quite gets there." He complained that most of the songs were uneventful, or uninspiring, and that they do not "lift you as a listener." PerthNow's Jay Hanna disagreed, claiming the album was "rippling with emotions". He said the album contained some "incredible moments", praising "Head Up in the Clouds", and calling "Nobody Sees" "Powderfinger at their devastating best", while giving the album four stars.Cameron Adams of Herald Sun HiT stated that the album contained no new directions for the band, and was highly consistent. He noted that the album contained less "rough edges and attitude" than predecessor Vulture Street, and likening the album more to Odyssey Number Five. Sputnikmusic's James Bishop agreed, claiming the band should be concerned by the "lack of experimentation or ambition" on the album. He again stated that the album was consistent, noting that "there actually isn't a bad song present". The review, which gave the album three and a half stars, commented that it seemed the band were trying to move towards the bluegrass genre, and "edging their way into the adult-contemporary section" of a music store, something they had not shown on their previous works.AllMusic's Clayton Bolger drew comparisons to Internationalist in his review, which gave the album 3 and a half stars. He said the album contained "all the trademarks of classic Powderfinger", praising Fanning's vocals, Middleton and Haug's "twin-guitar attack", Collins' basslines and Coghill's "powerhouse drum work". While praising "I Don't Remember" as an excellent anthem, and "Surviving" for containing "a sonic blast of rock", he was critical of "Lost and Running", which he said felt "tired and sluggish", while "Ballad of a Dead Man" was described as "tedious".
Output: What is publication does the critic who claimed the album had "all the trademarks of classic Powderfinger" write for?
