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: After groups of Chinese sugar mill workers revolted using custom-made weapons to loot and burn mills, hundreds of ethnic Chinese, suspected to have been led by Kapitein Nie Hoe Kong, killed 50 Dutch soldiers in Meester Cornelis (now Jatinegara) and Tanah Abang on 7 October. In response, the Dutch sent 1,800 regular troops, accompanied by schutterij (militia) and eleven battalions of conscripts to stop the revolt; they established a curfew and cancelled plans for a Chinese festival. Fearing that the Chinese would conspire against the colonials by candlelight, those inside the city walls were forbidden to light candles and were forced to surrender everything "down to the smallest kitchen knife". The following day the Dutch repelled an attack by up to 10,000 ethnic Chinese, led by groups from nearby Tangerang and Bekasi, at the city's outer walls; Raffles wrote that 1,789 Chinese died in this attack. In response, Valckenier called another meeting of the council on 9 October.Meanwhile, rumours spread among the other ethnic groups in Batavia, including slaves from Bali and Sulawesi, Bugis, and Balinese troops, that the Chinese were plotting to kill, rape, or enslave them. These groups pre-emptively burned houses belonging to ethnic Chinese along Besar River. The Dutch followed this with an assault on Chinese settlements elsewhere in Batavia in which they burned houses and killed people. The Dutch politician and critic of colonialism W. R. van Hoëvell wrote that "pregnant and nursing women, children, and trembling old men fell on the sword. Defenseless prisoners were slaughtered like sheep".Troops under Lieutenant Hermanus van Suchtelen and Captain Jan van Oosten, a survivor from Tanah Abang, took station in the Chinese district: Suchtelen and his men positioned themselves at the poultry market, while van Oosten's men held a post along the nearby canal. At around 5:00 p.m., the Dutch opened fire on Chinese-occupied houses with cannon, causing them to catch fire. Some Chinese died in the burning houses, while others were shot upon leaving their homes or committed suicide in desperation. Those who reached the canal near the housing district were killed by Dutch troops waiting in small boats, while other troops searched in between the rows of burning houses, killing any survivors they found. These actions later spread throughout the city. Vermeulen notes that many of the perpetrators were sailors and other "irregular and bad elements" of society. During this period there was heavy looting and seizures of property.
Who established a curfew and cancelled plans for a Chinese festival?

Passage: Washington, D.C. is located in the mid-Atlantic region of the U.S. East Coast. Due to the District of Columbia retrocession, the city has a total area of 68.34 square miles (177.0 km2), of which 61.05 square miles (158.1 km2) is land and 7.29 square miles (18.9 km2) (10.67%) is water. The District is bordered by Montgomery County, Maryland to the northwest; Prince George's County, Maryland to the east; Arlington County, Virginia to the south; and Alexandria, Virginia to the west.
The south bank of the Potomac River forms the District's border with Virginia and has two major tributaries: the Anacostia River and Rock Creek. Tiber Creek, a natural watercourse that once passed through the National Mall, was fully enclosed underground during the 1870s. The creek also formed a portion of the now-filled Washington City Canal, which allowed passage through the city to the Anacostia River from 1815 until the 1850s. The Chesapeake and Ohio Canal starts in Georgetown and was used during the 19th century to bypass the Little Falls of the Potomac River, located at the northwest edge of Washington at the Atlantic Seaboard fall line.The highest natural elevation in the District is 409 feet (125 m) above sea level at Fort Reno Park in upper northwest Washington. The lowest point is sea level at the Potomac River. The geographic center of Washington is near the intersection of 4th and L Streets NW.The District has 7,464 acres (30.21 km2) of parkland, about 19% of the city's total area and the second-highest percentage among high-density U.S. cities. This factor contributed to Washington, D.C., being ranked as third in the nation for park access and quality in the 2018 ParkScore ranking of the park systems of the 100 most populous cities in the United States, according to the nonprofit Trust for Public Land.The National Park Service manages most of the 9,122 acres (36.92 km2) of city land owned by the U.S. government. Rock Creek Park is a 1,754-acre (7.10 km2) urban forest in Northwest Washington, which extends 9.3 miles (15.0 km) through a stream valley that bisects the city. Established in 1890, it is the country's fourth-oldest national park and is home to a variety of plant and animal species, including raccoon, deer, owls, and coyotes. Other National Park Service properties include the C&O Canal National Historical Park, the National Mall and Memorial Parks, Theodore Roosevelt Island, Columbia Island, Fort Dupont Park, Meridian Hill Park, Kenilworth Park and Aquatic Gardens, and Anacostia Park. The D.C. Department of Parks and Recreation maintains the city's 900 acres (3.6 km2) of athletic fields and playgrounds, 40 swimming pools, and 68 recreation centers. The U.S. Department of Agriculture operates the 446-acre (1.80 km2) U.S. National Arboretum in Northeast Washington.
What is the country's fourth-oldest national park?

Passage: Somerset has 6,531 km (4,058 mi) of roads. The main arterial routes, which include the M5 motorway, A303, A37, A38, A39, A358 and A361 give good access across the county, but many areas can only be accessed via narrow country lanes.Rail services are provided by the West of England Main Line through Yeovil Junction, the Bristol to Exeter Line, Heart of Wessex Line which runs from Bristol Temple Meads to Weymouth and the Reading to Taunton Line. The key train operator for Somerset is Great Western Railway, and other services are operated by South Western Railway and CrossCountry.
Bristol Airport, located in North Somerset, provides national and international air services.
The Somerset Coal Canal was built in the early 19th century to reduce the cost of transportation of coal and other heavy produce. The first 16 kilometres (10 mi), running from a junction with the Kennet and Avon Canal, along the Cam valley, to a terminal basin at Paulton, were in use by 1805, together with several tramways. A planned 11.7 km (7.3 mi) branch to Midford was never built, but in 1815 a tramway was laid along its towing path. In 1871 the tramway was purchased by the Somerset & Dorset Joint Railway (S&DJR), and operated until the 1950s.
The 19th century saw improvements to Somerset's roads with the introduction of turnpikes, and the building of canals and railways. Nineteenth-century canals included the Bridgwater and Taunton Canal, Westport Canal, Glastonbury Canal and Chard Canal. The Dorset and Somerset Canal was proposed, but little of it was ever constructed and it was abandoned in 1803.
The usefulness of the canals was short-lived, though some have now been restored for recreation. The 19th century also saw the construction of railways to and through Somerset. The county was served by five pre-1923 Grouping railway companies: the Great Western Railway (GWR); a branch of the Midland Railway (MR) to Bath Green Park (and another one to Bristol); the Somerset and Dorset Joint Railway, and the London & South Western Railway (L&SWR). The former main lines of the GWR are still in use today, although many of its branch lines were scrapped as part of the Beeching cuts. The former lines of the Somerset & Dorset Joint Railway closed completely, as has the branch of the Midland Railway to Bath Green Park (and to Bristol St Philips); however, the L&SWR survived as a part of the present West of England Main Line. None of these lines, in Somerset, are electrified. Two branch lines, the West and East Somerset Railways, were rescued and transferred back to private ownership as "heritage" lines. The fifth railway was a short-lived light railway, the Weston, Clevedon & Portishead Light Railway. The West Somerset Mineral Railway carried the iron ore from the Brendon Hills to Watchet.

What ran along the Cam valley to a terminal basin at Paulton?
