Answer: C. The hobbits live together near a great field.
The correct option would be C. Option A assumes that the ropes and poles are there because of a birthday party, but the passage makes no mention of the cause. Option B similarly assumes that Bilbo is the cause of this commotion, which the passage similarly does not state. Option D claims Gaffer Gamgee to be lazy, even though the passage claims he was distracted, and not necessarily lazy. Option C, however, states that the hobbits live together near a field, which is information that is included in the passage.
