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: As the 19th century progressed, the United States government's Indian removal policy pushed Native American tribes west of the Mississippi River. In 1830, the Indian Removal Act was signed into law, and though that act did not directly address the Potawatomi people of Indiana, it led to several additional treaties that resulted in their removal. In what came to be known as the Potawatomi Trail of Death, about 860 Potawatomi Indians who had refused to leave were forced to move from Indiana to Kansas. On September 14, 1838, the group camped near Williamsport, and on September 15 they camped in the southwestern part of the county before moving into Illinois. Before reaching their destination in Kansas, over 40 of them had died, many of them children; two children died and were buried at the second Warren County campsite.When the county was established, the Wabash River was vital to transportation and shipping. Zachariah Cicott traded up and down the river, and cities like Attica, Perrysville, Baltimore and Williamsport were founded near the river's banks and flourished because of it. In the 1840s, the Wabash and Erie Canal began to operate and provided even broader shipping opportunities, but the canal favored towns which were on the "right side" of the river; the canal was on the Fountain County side, and towns like Baltimore dwindled as a result. Some towns, such as Williamsport and Perrysville, managed to participate in canal traffic through the use of side-cuts that brought traffic from the canal across the river. When railroads were constructed starting in the 1850s, they in turn began to render the canals obsolete and allowed trade to reach towns that lacked water connections. The canal continued to be used through the early 1870s.
[EX A]: What decade did the canals that provided broader shipping opportunities start to decline due to railroads?

[EX Q]: Passage: In the 2040s, a Martian research base, Tantalus Base outpost, is created. The eight person crew, who have been stationed there for six months, are only nineteen hours from the completion of their research mission. The spacecraft Aurora is inbound from Earth and will collect the team by lander. Mars scientist Marko Petrovic has found samples that may point to life on the planet. Without revealing his discovery, he devises a ruse for a last sojourn on the surface. Crewmate Richard Harrington drives Petrovic in a solar powered rover to the spot where he had found the sample. After he obtains soil with the biological agent present, a fissure swallows Petrovic.
Captain Charles Brunel and crewmate Lauren Dalby plan to explore the pit to retrieve Petrovic's body. Dalby remains at the pit but disappears before the team can return with equipment. Brunel authorizes Vincent Campbell to explore the pit and he finds a fungus-like life that grows in the fissure. Dalby and Petrovic reappear at the main outpost, but the Martian bacteria has mutated them into fast, aggressive, zombie-like creatures with blackened skin and no trace of their original personalities. Harrington dies from a power drill attack by one of the zombies and later revives as one himself. The remaining crew hold off the zombies while Brunel and Campbell return. Brunel is also fatally injured and reanimates, which provides the crew with new insight into the symptoms: thirst, memory loss and aggression.
[EX A]: What is the full name of the person who obtained the soil with the biological agent?

[EX Q]: Passage: It is 1862 in England. The Jupiter, a manned balloon with a unicorn-shaped gondola, falls from the sky during its maiden flight. Passenger Sir Henry Vining and his treasurer scream in horror. However, Professor Fergusson, the balloon's inventor, remains calm, as he planned on giving a dramatic demonstration showing the balloon's controls. On his signal, pilot Jacques, ascends the balloon using a pressure gauge that ensures no loss of gas or ballast. Traumatized by their "near-disaster", Sir Henry, head of the Royal Geographic Society, and his treasurer refuse to fund Jupiter's exploration of East Africa, and walk out on the professor after landing. American publisher Cornelius Randolph comes to the rescue: He will back the venture if his star reporter and nephew, Donald O'Shay, joins the crew. Unbeknownst to the professor, who is told by Randolph that O'Shea is an "inoffensive young man", O'Shay is notorious in the press for his troublesome antics as a playboy.
On the day Fergusson intends to set sail for Africa, he learns that his expedition is halted and that plans have been changed. At the British Parliament, the prime minister commissions Fergusson to defeat a convoy of slave traders heading toward uncharted land near the Volta River in West Africa. The slavers aim to stake their claim within six weeks and take over the territory. Fergusson calculates he needs only five weeks to cross Africa by air and plant the British flag at the river. The Prime Minister recommends that he take O'Shay along as a neutral witness to the planting of their flag. However, he did not calculate the Queen sending along Sir Henry, who proclaims himself to be the "expert on Africa" and demands to be called the "General".
[EX A]:
What is the full name of the person who signals the pilot?
