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.

Q: Passage: The Stooges are wannabe detectives who inadvertently get their chance to crack a case in Scotland. They manage to stumble on a lead concerning the priceless Punjab diamond being stolen by a crook named Dapper. With dreams of becoming genuine detectives, the trio head for Squid McGuffy's cafe asking for the whereabouts of Dapper. They manage to convince everyone at the restaurant that they are actually police.
While searching several rooms above the cafe, the Stooges stumble on Dapper's moll, who hastily hides the Punjab diamond in a candy dish. The boys refuse to leave, suspecting Dapper will eventually show his face. While killing time, Shemp starts to flirt with the moll, and manages to swallow the ice along with some mints from the candy dish. The gal nearly has a nervous breakdown but quickly discovers the Stooges are not actually real detectives. She calls in Dapper and his henchman Muscles and frantically try to pry the diamond out of frazzled Shemp.
After all else fails, Dapper decides to cut him open. Moe and Larry are locked in a closet by Muscles while Shemp is tied down on a close by desk-turned-operating table. As luck would have it, there happen to be a bag of tools in the closet, which Moe and Larry use to saw their way out of the closet, and right into a gorilla's cage on the other side of the wall. The gorilla knocks Moe, Larry, Dapper and Muscles cold. The beast, however, befriends Shemp, and helps him cough up the diamond. Moments later, Shemp explains how he managed to swallow the diamond by actually doing so again.

A: Who swallows the Punjab diamond?

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.

A: What decade did the canals that provided broader shipping opportunities start to decline due to railroads?

Q: Passage: The economy of El Hatillo Municipality consists of three sectors:  the commercial sector, which has been growing along with the population increase and is primarily represented by shopping malls and retail stores around the urban areas most of which sell typical crafts of the country; agricultural, in the southern half of the municipality and existing since the founding of El Hatillo; and  tourism, which contributes significantly to El Hatillo's income and is promoted by the government.El Hatillo is an accessible day visit destination for people from Caracas; the municipality is only 15 km (9.3 mi) southeast of downtown Caracas but in the mountains removed from the congested Caracas valley; thus, development has focused on day tourism. The central town square – Plaza Bolívar – and its surroundings are well maintained, and the municipal government offers bus trips around the narrow streets for viewing the colonial architecture of the town. Handcrafted souvenirs and products are popular purchases, offered at local artisan shops, and there are numerous restaurants.  There are at least three cultural centers in the municipality that attract tourists and residents to music festivals and art expositions.
To support the increasing population, numerous shopping malls have been built in the municipality. Neighborhoods like La Lagunita, Los Naranjos and El Hatillo Town now offer large scale shopping malls with multiplex movie theaters. Since the 1980s, the older typical houses of El Hatillo Town have been converted to shops and restaurants, while preserving their colonial architecture.Employment possibilities within El Hatillo – a bedroom community of Caracas – are reduced; businesses in the municipality are almost strictly commercial, and the economy has not expanded in other directions. Office space underdevelopment has resulted from a lack of land for large scale office construction, making it costly to locate large offices or businesses in the area. Those seeking employment in offices or larger businesses must look outside of El Hatillo, contributing to the high traffic to, from, and in El Hatillo.

A:
What are the names of the three sectors of the economy of El Hatillo Municipality?
