instruction:
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.
question:
Passage: The effects of flooding can be devastating and cause significant damage to crops and houses, serious bank erosive with consequent loss of homesteads, school and land, and loss of many lives, livestock and fisheries. During the 1998 flood, over 70% of the land area of Bangladesh was inundated, affecting 31 million people and 1 million homesteads. In the 1998 flood which had an unusually long duration from July to September, claimed 918 human lives and was responsible for damaging 16 00 and 6000 km of roads and embankments respectively, and affecting 6000 km2 of standing crops. The 2004 floods, over 25% of the population of Bangladesh or 36 million people, was affected by the floods; 800 lives were lost; 952 000 houses were destroyed and 1.4 million were badly damaged; 24 000 educational institutions were affected including the destruction of 1200 primary schools, 2 million governments and private tubewells were affected, over 3 million latrines were damaged or washed away, this increases the risks of waterborne diseases including diarrhea and cholera. Also, 1.1 M ha of rice crop was submerged and lost before it could be harvested, with 7% of the yearly aus (early season) rice crop lost; 270 000 ha of grazing land was affected, 5600 livestock perished together with 254 00 poultry and 63 MT of lost fish production.
answer:
How many average people were affected per homestead?


question:
Passage: Hoping to rebound from their road loss to the Vikings, the Texans went home for a Week 10 duel with the Baltimore Ravens.  Both teams were supposed to play each other in Week 2, but Hurricane Ike forced them to reschedule their game to this week. With QB Matt Schaub out with an injury, back-up QB Sage Rosenfels was given the start. In the first quarter, Houston trailed early as Ravens QB Joe Flacco completed a 43-yard TD pass to WR Yamon Figurs.  In the second quarter, the Texans responded with kicker Kris Brown getting a 23-yard field goal.  Baltimore would answer on a Houston blunder, as rookie OT Duane Brown committed a holding penalty in his own endzone, giving the Ravens a safety.  Baltimore added onto their lead as kicker Steven Hauschka got a 54-yard field goal.  The Texans closed out the half with Brown nailing a 48-yard field goal. In the third quarter, the Ravens increased their lead as RB Willis McGahee got a 1-yard TD run.  Houston responded as Rosenfels completed a 60-yard TD pass to WR Kevin Walter.  However, in the fourth quarter, Baltimore greatly pulled away as Flacco completed a 1-yard TD pass to TE Todd Heap (with a 2-point conversion pass to WR Derrick Mason), QB Troy Smith completed a 14-yard TD pass to Heap, and McGahee getting a 4-yard TD run.
answer:
HOw many yards was the longest touchdown pass?


question:
Passage: Tranmere started season 2016/17 brightly, top of the table at the end of August, gaining Gary Brabin the manager of the month.  However, form dipped which resulted in one goal scored in the next four games, with the 1-0 defeat to Sutton United on BT Sport resulting in Brabin being sacked on 18 September 2016.  Assistant manager, ex-Southport boss Paul Carden took the reins on an interim basis. On 6 October 2016, however, former Tranmere player Micky Mellon was appointed permanent manager. His first game in charge was against cross-border rivals Wrexham AFC, and a 2-0 victory for Tranmere.  Despite a 2nd-place finish and a club record 95 point haul, this still was not enough to gain automatic promotion back to the league.  Tranmere faced Aldershot Town in the playoffs.  A goal from James Norwood and a brace from Cole Stockton in the first leg away at the Recreation Ground (Aldershot) saw Rovers take a 3-0 aggregate lead back to Prenton Park for the second leg, which ended in a 2-2 draw, Norwood and Stockton once again on the scoresheet. This gave Tranmere a 5-2 aggregate win and their first Wembley appearance in 17 years.  On 14 May 2017, Tranmere suffered a 3-1 defeat in the Vanarama National League play-off final at the hands of Forest Green Rovers, Connor Jennings with Rovers first goal at Wembley since the 2000 Football League Cup Final.
answer:

How many weeks did it take Tranmere to find a permanent coach after firing Brabin?
