instruction:
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.
question:
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.
answer:
Whose men were unarmed against the Japanese?


question:
Passage: Mauna Kea is one of five volcanoes  that form the island of Hawaii, the largest and youngest island of the Hawaiian–Emperor seamount chain. Of these five hotspot volcanoes, Mauna Kea is the fourth oldest and fourth most active. It began as a preshield volcano driven by the Hawaii hotspot around one million years ago, and became exceptionally active during its shield stage until 500,000 years ago. Mauna Kea entered its quieter post-shield stage 250,000 to 200,000 years ago, and is currently dormant. Mauna Kea does not have a visible summit caldera, but contains a number of small cinder and pumice cones near its summit. A former summit caldera may have been filled and buried by later summit eruption deposits.
Mauna Kea is over 32,000 km3 (7,680 cu mi) in volume, so massive that it and its neighbor, Mauna Loa, depress the ocean crust beneath it by 6 km (4 mi).
Mauna Kea is the only Hawaiian volcano with distinct evidence of glaciation. Similar deposits probably existed on Mauna Loa, but have been covered by later lava flows. Despite Hawaii's tropical location, during several past ice ages a drop of a degree in temperature allowed snow to remain at the volcano's summit through summer, triggering the formation of an ice cap. There are three episodes of glaciation that have been recorded from the last 180,000 years: the Pōhakuloa (180–130 ka), Wāihu (80–60 ka) and Mākanaka (40–13 ka) series. These have extensively sculpted the summit, depositing moraines and a circular ring of till and gravel along the volcano's upper flanks. Subglacial eruptions built cinder cones during the Mākanaka glaciation, most of which were heavily gouged by glacial action. The most recent cones were built between 9000 and 4500 years ago, atop the glacial deposits, although one study indicates that the last eruption may have been around 3600 years ago.At their maximum extent, the glaciers extended from the summit down to between 3,200 and 3,800 m (10,500 and 12,500 ft) of elevation. A small body of permafrost, less than 25 m (80 ft) across, was found at the summit of Mauna Kea before 1974, and may still be present. Small gullies etch the summit, formed by rain- and snow-fed streams that flow only during winter melt and rain showers.
answer:
What was likely covered by later lava flows on Mauna Loa?


question:
Passage: Forced to give up his land and his only home, cantankerous Texas rancher Red Bovie isn't about to go quietly to the dismal trailer park that's all he can now afford, and instead goes off with his grandson Gally (son of his long-estranged son Jimmy) for a road trip to Old Mexico. They pick up two hitch-hikers who have stolen over $150,000 in drug money. But after Red drives off without them, unbeknownst to him the money remains in the car. They arrive in Mexico, still pursued by the drug dealers, who are pursued in turn by another hit-man looking to recover the stolen money. Red and Gally enjoy the town's attractions during the Mexican festival of the dead. As night falls, they visit a brothel where Red dances with the madame. They later meet a singer named Patty Wafers who is down on her luck. She is immediately attracted to Red's fearless and outrageous behavior. Meanwhile, the hit-man kills the American drug dealers and is now in pursuit of Red. Red discovers the money and desires to keep it so that he can have a better life than the one promised by the trailer park. Patty tries to help them return undetected across the border with the money, but the hit-man catches up with them and takes it. They pursue him, then they pursue another hit-man who has taken the money in turn. As Red and Patty's affection grows, Red begins to lose interest, but Gally, seeking his identity after the death of his father, takes up the pursuit in his place. They eventually overpower the second hit man and recover the money. Patty invites Red to live with her in her small town where she was born in northern Mexico. He accepts and is happy to go with her, knowing that with $150,000, they will live like royalty. As they part ways and Gally returns to the U.S., Red tells Gally that he has "found himself a grandson".
answer:

What is the name of Gally's grandfather?
