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.

Passage: Hoping to snap a six-game losing streak the Titans played on home ground for an AFC South rivalry rematch against the Texans. The Titans took the lead after QB Kerry Collins threw a 3 and a 1-yard TD pass to WR Nate Washington and to WR Justin Gage. This was followed by RB Chris Johnson getting an 11-yard TD run. The Texans got on the scoreboard after kicker Neil Rackers made a 37-yard field goal, but the Titans extended their lead after kicker Rob Bironas hit a 30-yard field goal. The lead was narrowed with QB Matt Schaub getting a 12-yard TD pass to WR Andre Johnson, but the Titans would pull away with RB Javon Ringer getting a 7-yard TD run. The lead was narrowed agan with Schaub throwing a 4-yard TD pass to WR Kevin Walter, but the Titans' defense prevented any more scoring chances.
How many field goals did the Texans make?

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

Passage: Nothing RB LaDainian Tomlinson does on the ground really impresses the San Diego Chargers at this point. For that, the star running back must take to the air. Tomlinson seemed to be trying to jump out of Candlestick Park while hurdling the goal line on one of his four touchdown runs&#8212;and his elevation was the Chargers' inspiration. Tomlinson set a franchise record while seemingly spending most of the afternoon in the end zone, and QB Philip Rivers passed for a career-high 334 yards and two more scores in San Diego's 48-19 victory over San Francisco. Tomlinson got his third score 33 seconds before halftime, capping San Diego's 35-point first half and essentially finishing off the 49ers (2-4) with an astonishingly high leap over the goal-line pile. WR Bryan Gilmore and FB Moran Norris caught scoring passes as the Chargers gave up more points in the first half alone than they allowed in any of their first four games. But San Diego shut out San Francisco in the second half, with QB Alex Smith finishing 20 of 31 for 214 yards. San Francisco's offense has been better than expected heading to the club's bye week, but the defense has been just as bad as feared. Two weeks after giving up 41 points to the Chiefs, the 49ers seemed lost from the moment top CB Walt Harris was ruled out with a hamstring injury. This crushing blow put the 49ers record at 2-4.

How many losses did the 49ers have after losing this game?
