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.

[EX Q]: Passage: Wedge Donovan is a tough construction boss, building airstrips in the Pacific for the U.S. Navy during World War II. He clashes with his liaison officer, Lieutenant Commander Robert Yarrow, over the fact that his men are not allowed to arm themselves against the Japanese. When the enemy lands in force on the island, he finally takes matters into his own hands, leading his men into the fray. This prevents Yarrow from springing a carefully devised trap that would have wiped out the invaders in a murderous machinegun crossfire, with minimal American losses. Instead, many of Donovan's men are killed unnecessarily.
As a result of this tragedy, Yarrow finally convinces the US Navy to form Construction Battalions (CBs, or the more familiar "Seabees") with Donovan's assistance, despite their mutual romantic interest in war correspondent Constance Chesley. Donovan and many of his men enlist and receive formal military training.
The two men are teamed together on yet another island. The Japanese launch a major attack, which the Seabees barely manage to hold off, sometimes using heavy construction machinery such as bulldozers and a clamshell bucket. When word reaches Donovan of another approaching enemy column, there are no sailors left to oppose this new threat. In desperation, he rigs a bulldozer with explosives on its blade, intending to ram it into a petroleum storage tank. The plan works, sending a cascade of burning liquid into the path of the Japanese, who retreat in panic, right into the sights of waiting machine guns. However, Wedge is shot in the process and dies in the explosion.
[EX A]: Whose men were unarmed against the Japanese?

[EX Q]: Passage: Two aliens, Nukie and Miko, spend their time flying through space in the form of stars and looking for fun. The two come across the planet Earth and, while trying to survey the planet, get caught in its gravitational pull and end up crash landing. During the crash, the two are separated, with Nukie ending up in the African savanna and Miko falling into the hands of a Space Federation in the United States. Upon discovering Miko's crash site, the agency take the alien in to perform tests on him, while Miko cries out for Nukie. Miko reaches out to Nukie telepathically and informs him that he is being held captive in America. The head of the operation, Dr. Glynn sends Dr. Eric Harvey to Nairobi to investigate the other crash site. During their experiments, the scientists discover that Miko is a being made of pure energy.
Nukie, meanwhile, begins to explore his surroundings, attempting to communicate telepathically with the animals he encounters to ascertain the location of America. The animals don't understand and much to Nukie's frustration run away. He then comes across two children, Tiko and Toki, who seem to be able to understand Nukie. He asks them for their help with finding America, but they run off vowing not to tell anybody about what has happened.
In America, Miko is subjected to more painful testing to explore his physical makeup. Miko's brain patterns show images of the animals which Nukie sees, indicating that Nukie is transmitting his brainwaves to Miko. Nukie decides to rest in the shade of a tree, turning invisible as he does so. Tiko and Toki pass by and Nukie is awoken by a flock of birds, becoming visible once more. He surmises that his light beam transformer must be working once more, and he succeeds in flying. Landing near a stream, he tastes the water and notices his reflection, which he claims is different from usual.
[EX A]: Who is the alien friend of the creature that crashes in the African savanna?

[EX Q]: Passage: After the painter's death in 1528, the portraits were held by his brother, and then his brother's widow before they passed into the collection of Willibald Imhoff, a grandson of Durer's friend Willibald Pirckheimer. Inventories from the Imhoff collection from 157374, 1580 and 1588 list both panels. The next surviving Imhoff inventory, of 1628, again lists the mother's portrait, but it disappears after mention in the 163358 account books of Hans Hieronymus Imhoff, after which its whereabouts became unknown. Durer expert Matthias Mende described the missing portrait of Barbara Holper as "among the most severe losses in the Durer oeuvre".
In 1977, art historian Lotte Brand Philip proposed that Unknown Woman in a Coif, held by the Germanisches Nationalmuseum in Nuremberg, was the original portrait of Barbara Holper. The Nuremberg panel was previously thought to have originated from a member of Wolgemut's workshop, a Franconian artist in his circle, or the anonymous Mainz painter Master W. B. Brand Philip's attribution was based on striking similarities in composition and its shared tone, theme and size with the father panel at the Uffizi. In both works the sitters are holding rosary beads, and Durer attentively describes their hands. Both portraits show the sitter in the same pose, against a similarly coloured background. Both are lit from the upper left. The boards are identically cut in width and depth, although 3 cm was removed from the left edge of Barbara's panel. Brand Philip noted the similarities between the panel and Durer's 1514 charcoal drawing Portrait of the Artist's Mother at the Age of 63. Fedja Anzelewsky agreed with the attribution, noting that both portraits bear, on their reverse, the catalogue number recorded in the Imhoff inventories, as well as "precisely the same design of masses of dark clouds".Anzelewsky speculated that the father's portrait, which was not listed in the 1628 Imhoff inventory, had been broken off and sold to Rudolph II of Austria. Hans Hieronymus Imhoff's lukewarm description of Barbara's portrait"the mother of Albrecht Durer in oil colors on wood, [but] there are many who do not believe it to be a work of Durer"led Brand Philip to conclude that Albrecht's panel was likely sold individually as the more accomplished and marketable of the two. The attribution is widely accepted today. In 2013 Stephan Kemperdick noted the sophistication of the Nuremberg portrait and that its three-dimensional modeling of the head displays a level of skill beyond Wolgemut and his circle.The two panels were reunited in 2012 during a Durer exhibition in Nuremberg having been separated since sometime between 1588 and 1628.
