This task involves creating answers to complex questions, from a given passage. Answering these questions, typically involve understanding multiple sentences. Make sure that your answer has the same type as the "answer type" mentioned in input. The provided "answer type" can be of any of the following types: "span", "date", "number". A "span" answer is a continuous phrase taken directly from the passage or question. You can directly copy-paste the text from the passage or the question for span type answers. If you find multiple spans, please add them all as a comma separated list. Please restrict each span to five words. A "number" type answer can include a digit specifying an actual value. For "date" type answers, use DD MM YYYY format e.g. 11 Jan 1992. If full date is not available in the passage you can write partial date such as 1992 or Jan 1992. If you find multiple spans, please add them all as a comma separated list. Please restrict each span to five words.

Example Input: Passage: Coming off their road win over the Panthers, the Bills went home for a Week 8 duel with the Houston Texans.  In the first quarter, Buffalo struck first as wide receiver Terrell Owens got a 29-yard touchdown run.  The Texans would answer in the second quarter with a 42-yard and a 22-yard field goal from kicker Kris Brown.  The Bills would end the half with kicker Rian Lindell's 21-yard field goal. Houston would creep closer in the third quarter with Brown booting a 26-yard field goal.  In the fourth quarter, the Texans would take the lead and never look back as running back Ryan Moats got three touchdown runs of 11 yards (followed by quarterback Matt Schaub's 2-point conversion pass to wide receiver Andre Johnson), 1 yard, and 3 yards. With the loss, Buffalo went into their bye week at 3-5. Despite the loss, rookie safety Jairus Byrd once again had two interceptions.  He would become the first rookie and only the second player in NFL history to have three-straight multi-interception games. 
Question: How many field goals were scored in the second half? 
Answer type: Number 
Example Output: 1.

Example Input: Passage: Those who landed at Skagway made their way over the White Pass before cutting across to Bennett Lake. Although the trail began gently, it progressed over several mountains with paths as narrow as 2 feet  and in wider parts covered with boulders and sharp rocks. Under these conditions horses died in huge numbers, giving the route the informal name of Dead Horse Trail. The volumes of travellers and the wet weather made the trail impassable and, by late 1897, it was closed until further notice, leaving around 5,000 stranded in Skagway. An alternative toll road suitable for wagons was eventually constructed and this, combined with colder weather that froze the muddy ground, allowed the White Pass to reopen, and prospectors began to make their way into Canada. Moving supplies and equipment over the pass had to be done in stages. Most divided their belongings into 65 pounds  packages that could be carried on a man's back, or heavier loads that could be pulled by hand on a sled. Ferrying packages forwards and walking back for more, a prospector would need about thirty round trips, a distance of at least 2,500 miles , before they had moved all of their supplies to the end of the trail. Even using a heavy sled, a strong man would be covering 1,000 miles  and need around 90 days to reach Lake Bennett. 
Question: How many miles did prospectors take for ferrying packages? 
Answer type: Number 
Example Output:
2500.
