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: Sanders is a British colonial District Commissioner in Colonial Nigeria. He tries to rule his province fairly, including the various tribes comprising the Peoples of the River. He is regarded with respect by some and with fear by others, among whom he is referred to as "Sandi" and "Lord Sandi". He has an ally in Bosambo, a literate and educated chief (played by the American actor, Paul Robeson).
When Sanders goes on leave, another chief, King Mofolaba, spreads the rumour that "Sandi is dead." Inter-tribal war seems inevitable, and the situation is made worse by gun-runners and slavers.
His relief, Ferguson (known to the natives as Lord Ferguson), is unequal to the task; he is captured and killed by King Mofolaba. Sanders returns to restore peace. When Bosambo's wife Lilongo is kidnapped, the chief tracks down her kidnappers. Captured by them, he is saved by a relief force commanded by Sanders. Bosambo kills King Mofolaba and is subsequently named by Sanders as the King of the Peoples of the River.
What is the real name of Sandi?

Passage: Charlemagne planned to continue the Frankish tradition of dividing his kingdom between all his heirs, but was unable to do so as only one son, Louis the Pious (r. 814–840), was still alive by 813. Just before Charlemagne died in 814, he crowned Louis as his successor. Louis's reign of 26 years was marked by numerous divisions of the empire among his sons and, after 829, civil wars between various alliances of father and sons over the control of various parts of the empire. Eventually, Louis recognised his eldest son Lothair I (d. 855) as emperor and gave him Italy. Louis divided the rest of the empire between Lothair and Charles the Bald (d. 877), his youngest son. Lothair took East Francia, comprising both banks of the Rhine and eastwards, leaving Charles West Francia with the empire to the west of the Rhineland and the Alps. Louis the German (d. 876), the middle child, who had been rebellious to the last, was allowed to keep Bavaria under the suzerainty of his elder brother. The division was disputed. Pepin II of Aquitaine (d. after 864), the emperor's grandson, rebelled in a contest for Aquitaine, while Louis the German tried to annex all of East Francia. Louis the Pious died in 840, with the empire still in chaos.A three-year civil war followed his death. By the Treaty of Verdun (843), a kingdom between the Rhine and Rhone rivers was created for Lothair to go with his lands in Italy, and his imperial title was recognised. Louis the German was in control of Bavaria and the eastern lands in modern-day Germany. Charles the Bald received the western Frankish lands, comprising most of modern-day France. Charlemagne's grandsons and great-grandsons divided their kingdoms between their descendants, eventually causing all internal cohesion to be lost. In 987 the Carolingian dynasty was replaced in the western lands, with the crowning of Hugh Capet (r. 987–996) as king. In the eastern lands the dynasty had died out earlier, in 911, with the death of Louis the Child, and the selection of the unrelated Conrad I (r. 911–918) as king.The breakup of the Carolingian Empire was accompanied by invasions, migrations, and raids by external foes. The Atlantic and northern shores were harassed by the Vikings, who also raided the British Isles and settled there as well as in Iceland. In 911, the Viking chieftain Rollo (d. c. 931) received permission from the Frankish King Charles the Simple (r. 898–922) to settle in what became Normandy. The eastern parts of the Frankish kingdoms, especially Germany and Italy, were under continual Magyar assault until the invader's defeat at the Battle of Lechfeld in 955. The breakup of the Abbasid dynasty meant that the Islamic world fragmented into smaller political states, some of which began expanding into Italy and Sicily, as well as over the Pyrenees into the southern parts of the Frankish kingdoms.
What is the name of the person whose entire family except one son was deceased by 813?

Passage: On Christmas Eve, the submarine USS Copperfin, under the command of Captain Cassidy, departs San Francisco on a secret mission. At sea, Cassidy opens his sealed orders, which direct him to proceed first to the Aleutian Islands to pick up meteorologist Lt. Raymond, then to Tokyo Bay to obtain vital weather intelligence for the upcoming Doolittle Raid.
On the way, two Japanese planes attack; both are shot down, but one pilot manages to parachute into the water. When Mike goes to pick him up, he is stabbed to death. New recruit Tommy Adams shoots the pilot, but because he was slow to react, Tommy blames himself for Mike's death and volunteers to defuse an unexploded bomb stuck under the deck. When Mike is buried at sea, Greek-American "Tin Can" (Dane Clark) does not attend the service, which angers the other men until he explains that every Allied death causes him great pain.  Meanwhile, Raymond, who lived in Japan, discusses how the Japanese people were led into the war by the military faction.
As the submarine nears Tokyo Bay, the Copperfin has to negotiate its way through protective minefields and anti-torpedo nets. When a Japanese ship enters the bay, Cassidy follows in its wake. That night, a small party, including the ship's womanizer, "Wolf" (John Garfield), goes ashore to make weather observations. Meanwhile, Tommy is diagnosed with  appendicitis. "Pills", the pharmacist's mate, has to operate following instructions from a book, using improvised instruments, and without sufficient ether to last throughout the procedure.  The operation is a success, and "Cookie" Wainwright begins to prepare the pumpkin pie he had promised to bake for Tommy.

What rank is the man who opens his sealed orders?
