airline录音原文中的rely on“依靠，取决于”是题目verified by“由……证实，核实”的同义替换。录音原文中表示rely on information from the air-line，因此答案为airline。

(Sales Assistant=S    Customer=C)
S: Good morning. Take a seat. I see you’ve picked up some of our brochures.
C: Yes. I’ve been reading the one on travel.
S: Would the travel insurance be for you, or for your family as well?
C: Just for me.
S: So, individual?
C: That’s right.
S: Are you looking for a basic or a comprehensive policy?
C: To be honest, I’ve had basic in the past, but it didn’t pay out very much.
S: That’s often true. With our company, you can be insured for different amounts. For instance, in Section 1: Baggage and personal effects, you can be insured for all five subsections or for as few as two.
C: I think I’d like insurance for all five since I’m going to some unsafe places.
S: Wise decision.
C: By the way, can a camera be counted as a single item, or must it be included in Cameras and portable electronic equipment?
S: If you have an expensive camera, you can nominate it as a single item. Our maximum payout is $1,500.  Occasionally, people have their camera and computer stolen together. If insurance is only taken out on Subsection 2, this may not cover the replacement of both things.
C: That’s what happened with my previous policy. However, in that one, there was a higher limit forlost or stolen money: yours is only $700.
S: These days, with credit cards, people don’t carry much cash,so we’ve set the limit accordingly. Still, we pay out well for Documents.
C: Indeed. In the Disrupted travel section, ‘reasonable costs’ is written for a missed connection or an early return, instead of an amount of money. What exactly are reasonable costs?
S: Put it this way: if you miss your flight due to poor weather that is verifiable, we pay $300 per day of lost time. If you arrive at check-in as the aircraft is leaving because you overslept, we still pay out, but only $100 a day. We rely on information from the airline to determine this.
