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: Superferry 14 was a large ferry destroyed by a bomb on 27 February 2004, killing 116 people in the Philippines' worst terrorist attack and the world's deadliest terrorist attack at sea. On that day, the 10,192 ton ferry sailed out of Manila with about 900 passengers and crew on board. A television set filled with 8 lb.  of TNT had been placed on board. 90 minutes out of port, the bomb exploded. 63 people were killed instantly and 53 were missing and presumed dead. Despite claims from terrorist groups, the blast was initially thought to have been an accident caused by a gas explosion. However, after divers righted the ferry five months after it had sunk, they found evidence of a bomb blast. A man called Redendo Cain Dellosa admitted to planting the bomb for Abu Sayyaf. Six suspects were arrested in connection with the bombing while the masterminds, Khadaffy Janjalani and Abu Sulaiman, were killed.
How many days did the worst terrorist attack and the world's deadliest terrorist attack at sea overlap?

Passage: The Eagles donned their throwback uniforms (in celebration of the franchise's 50th Anniversary of their 1960 championship team) and began their season at home for an NFC duel with the Green Bay Packers.  In the first quarter, Philadelphia had the early lead with kicker David Akers making a 45-yard field goal, but failed to maintain it in the second quarter with Packers kicker Mason Crosby nailing a 49-yard field goal, followed by quarterback Aaron Rodgers throwing  a 6-yard touchdown pass to wide receiver Donald Driver, followed by Crosby hitting a 56-yard field goal. In the third quarter, the Green Bay fullback John Kuhn pushed up the middle for a 3-yard touchdown run, but replied with running back LeSean McCoy running in a 12-yard TD run. However, the Packers extended their lead with Rodgers bombing a 32-yard touchdown pass to wide receiver Greg Jennings. The Eagles cut the lead in the 4th quarter with quarterback Michael Vick tossing a 17-yard touchdown pass to wide receiver Jeremy Maclin, and with Akers nailing a 24-yard field goal, but couldn't do enough, giving the Eagles a loss. With the loss, the Eagles began the season at 0-1. They also lost Leonard Weaver, who was considered to be the best fullback in the NFL in 2009 and had just been signed to a record-breaking fullback, to a career ending injury.
How many field goals did David Akers make?

Passage: After suffering a disappointing loss to the previously winless Jaguars the week before, the Browns faced yet another winless opponent in the Oakland Raiders.  Both teams struggled for much of the game, kicking a combined five field goals as the Browns held a 9-6 second half lead.  At the end of the third quarter the Browns finally got the break they needed when S Joe Haden recovered a Darren McFadden fumble deep in Cleveland territory and returned it 34 yards.  Four plays later, QB Brian Hoyer found WR Andrew Hawkins for a four-yard touchdown pass and a 16-6 lead.  The Raiders would never recover and the Browns, despite giving up the Raiders' lone touchdown pass from Derek Carr to Andre Holmes with 7 seconds left, won the game 23-13.

How many points were the Browns ahead by at the half?
