TASK DEFINITION: This task involves creating questions from a given passage that involve some kind of complex reasoning (including numerical reasoning). 
The generated questions must require looking at more than one part of the passage to answer. Try to use a variety of reasoning types in your questions (some of the sample reasoning types are illustrated in the 'positive examples' field) and also have a variety of answer types (spans, numbers, dates). A span is a continuous phrase taken directly from the passage or question. In such questions, the answer spans are recommended to be five words. Questions with answer type "number", are expected to start with "How many". For instance, "How long did an event last?" can be phrased as "How many years did an event last?". To increase diversity, try to create more questions for which the answer will be multiple spans. Please create questions that require AT LEAST 2 arithmetic operations as illustrated in the 'positive examples' field. You are encouraged to try DIFFERENT COMBINATIONS of operations and not just limit to the combinations shown in those examples. The more challenging questions you create, the better it is.
PROBLEM: Passage: In order to regain control of the custom duties, the emperor John VI Kantakouzenos made preparations to lower Constantinople's duties and most tariffs to undercut the Genoese in Galata. Still recovering from the civil war of 1341-1347, the emperor, with great difficulty, raised 50,000 hyperpyra from private sources  for a shipbuilding program for the expected war to come. When the tariffs and custom duties were finally lowered, merchant shipping coming through the strait bypassed Genoese Galata and diverted their ships across the Golden Horn to Byzantine Constantinople. The Genoese, financially hard-hit from this policy, declared war on the Empire, and in August 1348, a flotilla of ships sailed across the Horn and attacked the Byzantine fleet; despite their large scale preparations, the Byzantine fleet was destroyed by early 1349. The Byzantines retaliated by burning wharves and warehouses along the shore and catapulted stones and burning bales of hay into Galata, setting major parts of the city on fire. After several weeks of fighting, plenipotentiaries from Genoa came and negotiated a peace agreement. The Genoese agreed to pay a war indemnity of 100,000 hyperpyra and evacuated the land behind Galata which they illegally occupied; last, they promised never to attack Constantinople. In return the Byzantines surrendered nothing, but the Genoese custom duties remained in effect.

SOLUTION: Approximately how many years did it take for the Byzantine fleet to be destroyed after August 1348?

PROBLEM: Passage: Trying to snap a three-game losing skid, the Titans went home for a Week 13 AFC South rematch with the Houston Texans. In the first quarter, Tennessee trailed early as Texans RB Ron Dayne got a 1-yard TD run. Afterwards, the Titans responded with RB LenDale White getting a 1-yard TD run. In the second quarter, Houston regained the lead with kicker Kris Brown getting a 45-yard field goal for the only score of the period. In the third quarter, Tennessee took the lead as QB Vince Young completed a 43-yard TD pass to WR Roydell Williams, along with an 11-yard TD pass to WR Justin Gage. In the fourth quarter, the Texans crept closer with QB Sage Rosenfels completing a 28-yard TD pass to WR Andre Johnson. Afterwards, the Titans replied with RB Chris Brown getting a 7-yard TD run. Later, Houston managed to get a 50-yard field goal from Brown. Afterwards, Tennessee's defense help secure the guarantee of their three-game skid coming to an end. With the season-sweeping win, the Titans improved to 7-5. This marked the third-straight year that Tennessee has swept the Texans.

SOLUTION: How many 1-yard touchdown runs were there in the game?

PROBLEM: Passage: Beyond Indonesia's art deco architecture also much of the country's rail and road infrastructure as well as its major cities were built during the colonial period. Many of Indonesia's main cities were mere rural townships before colonial industrialization and urban development. Examples on Java include the capital Jakarta and Bandung, outside Java examples include Ambon and Menado city. Most main railroads and rail stations on Java as well as the main road, called Daendels Great Post Road  after the Governor General commissioning the work, connecting west to east Java were also built during the Dutch East Indies era. Between 1800 and 1950 Dutch engineers created an infrastructure including 67,000 kilometers  of roads, 7,500 kilometers  of railways, many large bridges, modern irrigation systems covering 1.4 million hectares  of rice fields, several international harbors, and 140 public drinking water systems. These Dutch constructed public works became the material base of the colonial and postcolonial Indonesian state.

SOLUTION:
Did Dutch enginners create less kilometers of roads or railways?
