我這個questionnaire該怎麽填呢？

因為做腹腔鏡手術造成氣胸。現在保險公司來了封問卷調查，需在15天內回答，否則也許會拒付。
1， Auto/Motorcycle Accident    2,Work/ Industrial Accident   3,Other (slip &fall) Accident  4, No Accident  

If this accident was not Auto/Motorcy or Workers' Compensation related, but there is another party that was liable, fill out Section 1,2 and 4.
If there is no other party liable for your injury, check no accident and fill out section 1.
