Given the task definition, example input & output, solve the new input case.
In this task, you're given a context passage, followed by a question that needs to be answered. Based on the paragraph, you must write unambiguous answers to the questions and your answer must refer to a specific phrase from the paragraph. If multiple answers seem to exist, write the answer that is the most plausible.
Example: Tracy slept awkwardly on their new bed and was having some pain, so Tracy cracked her neck.
Question: What did Tracy do with her neck?
Output: crack her neck
The output phrase perfectly answers the question and is explicitly mentioned in the passage as well.

New input case for you: I was at camp and getting ready to lead a workshop teaching cooking on a campfire. Luckily it had not rained for a few days so all the wood in the area was dry. I had some large logs that were sitting by the fire ring so I went searching for some smaller sticks and kindling. I built a log cabin structure out of the larger logs. Inside the log cabin structure I put some very small tinder as well as some balled up pieces of newspaper. I lit the newspaper and continued adding very small pieces of wood to it. When the small pieces started catching I started adding larger twigs. As smaller pieces started catching on fire I kept added larger and larger twigs and sticks until the big logs started burning. I continued to add sticks so I could get a nice sized fire burning that would create lots of hot coals so we could cook on them.
Question: How long did it take to build the fire?
Output:
less than an hour
