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: In the 2040s, a Martian research base, Tantalus Base outpost, is created. The eight person crew, who have been stationed there for six months, are only nineteen hours from the completion of their research mission. The spacecraft Aurora is inbound from Earth and will collect the team by lander. Mars scientist Marko Petrovic has found samples that may point to life on the planet. Without revealing his discovery, he devises a ruse for a last sojourn on the surface. Crewmate Richard Harrington drives Petrovic in a solar powered rover to the spot where he had found the sample. After he obtains soil with the biological agent present, a fissure swallows Petrovic.
Captain Charles Brunel and crewmate Lauren Dalby plan to explore the pit to retrieve Petrovic's body. Dalby remains at the pit but disappears before the team can return with equipment. Brunel authorizes Vincent Campbell to explore the pit and he finds a fungus-like life that grows in the fissure. Dalby and Petrovic reappear at the main outpost, but the Martian bacteria has mutated them into fast, aggressive, zombie-like creatures with blackened skin and no trace of their original personalities. Harrington dies from a power drill attack by one of the zombies and later revives as one himself. The remaining crew hold off the zombies while Brunel and Campbell return. Brunel is also fatally injured and reanimates, which provides the crew with new insight into the symptoms: thirst, memory loss and aggression.

Output: What is the full name of the person who obtained the soil with the biological agent?

Input: Consider Input: Passage: Metallica was formed in Los Angeles, California, in late 1981 when Danish-born drummer Lars Ulrich placed an advertisement in a Los Angeles newspaper, The Recycler, which read, "Drummer looking for other metal musicians to jam with Tygers of Pan Tang, Diamond Head and Iron Maiden." Guitarists James Hetfield and Hugh Tanner of Leather Charm answered the advertisement. Although he had not formed a band, Ulrich asked Metal Blade Records founder Brian Slagel if he could record a song for the label's upcoming compilation album, Metal Massacre. Slagel accepted, and Ulrich recruited Hetfield to sing and play rhythm guitar. The band was officially formed on October 28, 1981, five months after Ulrich and Hetfield first met.The bandname came from Ulrich's friend Ron Quintana, who was brainstorming names for a fanzine and was considering MetalMania or Metallica. After hearing the two names, Ulrich wanted Metallica for his band, so he suggested Quintana use MetalMania instead. Dave Mustaine replied to an advertisement for a lead guitarist; Ulrich and Hetfield recruited him after seeing his expensive guitar equipment. In early 1982, Metallica recorded its first original song, "Hit the Lights", for the Metal Massacre I compilation. Hetfield played bass, rhythm guitar and sang while Lloyd Grant was credited with a guitar solo and Lars Ulrich played drums. Metal Massacre I was released on June 14, 1982; early pressings listed the band incorrectly as "Mettallica", angering the band. The song generated word of mouth and the band played its first live performance on March 14, 1982, at Radio City in Anaheim, California, with newly recruited bassist Ron McGovney. Their first live success came early; they were chosen to open for British heavy metal band Saxon at one gig of their 1982 US tour. This was Metallica's second gig. Metallica recorded its first demo, Power Metal, whose name was inspired by Quintana's early business cards in early 1982.

Output: What was the full name of the person that asked Brian Slagel if he could record a song?

Input: Consider Input: Passage: Dodo Doubleday has been inexplicably reduced from first sergeant to staff sergeant and has resumed being orderly to his regimental commander Colonel Barkley. Sergeant Ames is still a buck sergeant who hates Dodo because he advanced to outrank Ames within Dodo's first 24 hours in the army. Dodo's former comrade in arms Charlie Cobb is also a buck sergeant. As both Cobb and Ames are the best marksman in the regiment but constantly boast of their prowess, Colonel Barkley seeks to find an expert who can outshoot them.
Though possessing a photographic memory that enabled him to advance from private to senior non-commissioned officer in less than 24 hours, Dodo has one weakness: though his book knowledge enables him to give lectures on weapons disassembly and ballistics, he is gun shy and an incompetent marksman. After nearly shooting several of his fellow soldiers on the pistol range, with the actual target being the safest place to hide, Dodo is ordered to go into the woods to practice. There his missed shots impress the picnicking colonel and his daughter Betty when Dodo accidentally shoots a hawk through the eye whilst in flight and after the colonel catches a fish who breaks the line and is in the process of rolling back into the water, an accidental discharge from Dodo's pistol shoots the fish through his eye. Eager to deflate the boasting Ames and Cobb, the colonel bets a month's pay that Dodo can outshoot Ames and Cobb.
Ames and Cobb's hatred of Dodo increases when in the interests of promoting democracy in the United States Army, Betty invites Dodo to dinner at the colonel's quarters, but Ames and Cobb believe they have been invited as well.
Output: What is the full name of the person who has a photographic memory?
