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.

Passage: Albrecht the Elder was 62 or 63  when his panel was painted early in 1490. Barbara's portrait may have been completed soon after, when she would have been around 39. Their son was around 18 and had just completed his apprenticeship with Michael Wolgemut, and would soon leave for Nuremberg to travel as a journeyman painter. The father panel was painted first; for aesthetic reasons Dürer may have waited a year or two until his mother looked older.The sitters are presented in three-quarter view before flat, nondescript lacquer-like green backgrounds, which although lushly coloured, are thinly layered. Each has a white ground and light red imprimatura with lead content. The sitter's form and pose echo and in many ways counterbalance each other. Brand Philip draws attention to the similarities of the panels' linear construction, especially the manner in which the folds and lines of their clothing form triangular shapes. The train of Barbara's headdress across her chest corresponds with the opening of Albrecht's fur-lined coat. It was more usual in pendant portraits of this type for the male to be on the left-hand side; the positioning here may be an indication that Dürer originally intended his father's panel to stand alone, given that Barbara's was painted some time later.Albrecht the Elder's panel is regarded as the superior of the two works. This may in part be attributed to differing contemporary treatments of male and female portraits; men were allowed more individuality, while female portraits were bound by stereotypes and were not as daring, for example showing evidence of ageing. In either case, the father painting is far more closely detailed, especially in the lining of clothing, which is summary in Barbara's panel, compared to the long seam of her husband's gown. This contrast in detail can also be seen in the treatment of the rosaries, which are given prominence and a glowing red colour in his panel, but are small and relegated in hers.Albrecht the Elder's panel is usually, but not always, thought to be the first of the two to be executed and, if so, is the earliest extant example of his son's painting. In contrast, a number of art historians have noted that his mother's portrait contains bland passages, especially around the eyes and may be a near-contemporary copy of a lost original. Lotte Brand Philip believes the clumsiness in the mother panel indicated that Dürer painted it first, as a youthful attempt at portraiture, and that Albrecht the Elder might have later "commissioned" his own portrait to pair with Barbara's. Recent technical examination of the two panels confirms that Barbara's portrait was painted later than her husband's.
What is the name of the person that completed his apprenticeship with Michael Wolgemut?

Passage: As three US servicemen – Marine Private First Class Ira Hayes, Private First Class Rene Gagnon, and Navy Corpsman John "Doc" Bradley – are feted as heroes in a war bond drive, they reflect on their experiences via flashback.
After training at Camp Tarawa in Hawaii, the 28th Marine Regiment 5th Marine Division sails to invade Iwo Jima. The Navy bombards suspected Japanese positions for three days. Sergeant Mike Strank is put in charge of Second Platoon.
The next day, February 19, 1945, the Marines land in Higgins boats and LVTs. The beaches are silent and Private First Class Ralph "Iggy" Ignatowski wonders if the defenders are all dead before Japanese heavy artillery and machine guns open fire on the advancing Marines and the Navy ships. Casualties are heavy, but the beaches are secured.
Two days later, the Marines attack Mount Suribachi under a rain of Japanese artillery and machine gun fire, as the Navy bombards the mountain. Doc saves the lives of several Marines under fire, which later earns him the Navy Cross. The mountain is eventually secured.
On February 23, the platoon under command of Sergeant Hank Hansen reaches the top of Mount Suribachi and hoists the United States flag to cheers from the beaches and the ships. Secretary of the Navy James Forrestal, who witnesses the flag raising as he lands on the beach, requests the flag for himself. Colonel Chandler Johnson decides his 2nd Battalion deserves the flag more. Rene is sent up with Second Platoon to replace the first flag with a second one for Forrestal to take. Mike, Doc, Ira, Rene, and two other Marines (Corporal Harlon Block and Private First Class Franklin Sousley) are photographed by Joe Rosenthal as they raise the second flag.
On March 1, the Second Platoon is ambushed from a Japanese machine gun nest. During the fight over the nest, Mike is hit by a U.S. Navy shell and dies from his wounds. Later that day, Hank is shot in the chest and dies, and Harlon is killed by machine gun fire.
What are the full names of the men who raise the second flag on Mount Suribachi?

Passage: Nansen's Fram expedition of 1893–96 was an attempt by the Norwegian explorer Fridtjof Nansen to reach the geographical North Pole by harnessing the natural east–west current of the Arctic Ocean. In the face of much discouragement from other polar explorers, Nansen took his ship Fram to the New Siberian Islands in the eastern Arctic Ocean, froze her into the pack ice, and waited for the drift to carry her towards the pole.  Impatient with the slow speed and erratic character of the drift, after 18 months Nansen and a chosen companion, Hjalmar Johansen, left the ship with a team of dogs and sledges and made for the pole. They did not reach it, but they achieved a record Farthest North latitude of 86°13.6′N before a long retreat over ice and water to reach safety in Franz Josef Land. Meanwhile, Fram continued to drift westward, finally emerging in the North Atlantic Ocean.
The idea for the expedition had arisen after items from the American vessel Jeannette, which had sunk off the north coast of Siberia in 1881, were discovered three years later off the south-west coast of Greenland. The wreckage had obviously been carried across the polar ocean, perhaps across the pole itself. Based on this and other debris recovered from the Greenland coast, the meteorologist Henrik Mohn developed a theory of transpolar drift, which led Nansen to believe that a specially designed ship could be frozen in the pack ice and follow the same track as Jeannette wreckage, thus reaching the vicinity of the pole.
Nansen supervised the construction of a vessel with a rounded hull and other features designed to withstand prolonged pressure from ice. The ship was rarely threatened during her long imprisonment, and emerged unscathed after three years. The scientific observations carried out during this period contributed significantly to the new discipline of oceanography, which subsequently became the main focus of Nansen's scientific work. Fram's drift and Nansen's sledge journey proved conclusively that there were no significant land masses between the Eurasian continents and the North Pole, and confirmed the general character of the north polar region as a deep, ice-covered sea. Although Nansen retired from exploration after this expedition, the methods of travel and survival he developed with Johansen influenced all the polar expeditions, north and south, which followed in the subsequent three decades.

What is the full name of the person whose ship was frozen into the pack ice while waiting for the drift to carry her towards the North Pole?
