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: Briarcliff Manor's original settlement was known as Whitson's Corners for brothers John H., Richard, and Reuben Whitson, who owned adjoining farms in the area totaling 400 acres (160 ha). Whitson's Corners was named after the corner of Pleasantville and South State Roads, where John H. Whitson's house, the Crossways, stood from 1820 until the 1940s. The Briarcliff Congregational Church's parish house currently stands at its former location. The neighboring community of Scarborough was known as Weskora until it was renamed in 1864, after resident William Kemey's ancestral hometown in Yorkshire. After the community was incorporated into Briarcliff Manor in 1906, the New York Central and Hudson River Railroad put up a sign reading "Briarcliff West" at the village's Scarborough station. Soon afterward, attributed to the neighborhood's pride over their name, that sign was thrown into the Hudson River and replaced with the original Scarborough sign.Briarcliff Manor derives from "Brier Cliff", a compound of the English words "brier" and "cliff". The name originated in Ireland as that of the family home of John David Ogilby, a professor of ecclesiastical history at the General Theological Seminary. Ogilby had named his New York summer home Brier Cliff after his family home in Ireland. In 1890, Walter Law bought James Stillman's 236-acre (96 ha) Briarcliff Farm and further developed it, later using the name Briarcliff for all his property. Law's friend, Andrew Carnegie, called him "The Laird of Briarcliff Manor"; since the title appealed to all concerned, the village was named "Briarcliff Manor". By 1897, the village post office and railroad station bore the name Briarcliff Manor. The village (and its name) were approved by its residents in a September 12, 1902 referendum; the name prevailed over other suggestions, including "Sing Sing East". On November 21, 1902, the village of Briarcliff Manor was established.The village is also known by several other names. It is conversationally called "Briarcliff", and often erroneously written as "Briar Cliff Manor" (although historically there has been little distinction). The village has been called "Briarcliff on the Hudson" by Mark Twain and Aileen Riggin; it is also known as "the Village of Briarcliff Manor". The name Briarcliff has also been applied to other municipalities, including the 470-person town of Briarcliffe Acres in South Carolina; in naming it, the town's founder had drawn inspiration from Briarcliff Manor's name.
What house now stands were John H. Whitson's house use to be?

Passage: Taapaca is part of the Central Volcanic Zone of the Andes, which along with the Northern Volcanic Zone, the Southern Volcanic Zone and the Austral Volcanic Zone is one of the four volcanic belts of the Andes; these volcanic belts are separated by areas where no recent volcanism has occurred.The Central Volcanic Zone has about 44 active volcanoes and several other caldera/ignimbrite and volcanic field centres. Older volcanoes are often well preserved owing to the dry climate. This volcanic zone features the highest volcanoes in the world, which reach elevations of 5,000–7,000 metres (16,000–23,000 ft) here. The largest historical eruption in the Central Volcanic Zone occurred at Huaynaputina in 1600 and Lascar is the most active volcano in the region; otherwise volcanic activity is poorly recorded as most edifices are remote from human habitation.Taapaca is located on the western margin of the Altiplano, where the Western Cordillera has developed since the Oligocene. The basement beneath the volcano is formed by several principally volcanic formations, including the Lupica and sedimentary Huaylas formations and the Lauca ignimbrite (2.72 million years old); this basement is of Oligocene to Pliocene age. In some places, a Proterozoic basement formed by amphibolites, gneisses and serpentinites crops out. The volcanoes of Condoriri, Pomerape, Larancagua and Parinacota lie to the east of Taapaca. The area of the volcano is subject to contractional tectonics, with a major thrust fault passing close by, but their relationship to Taapaca's volcanism is not clear.

What volcanic belts are separated by areas where no recent volcanism has occurred?
