Text 9

M: Are you looking forward to your trip to Canada, Susan？

W: I can't wait to see Canada, Jason, but I'm scared stiff of the journey. My husband insists on flying, but I want to sail. Planes make me nervous.

M: There's nothing to be frightened of. How many planes fly across the Atlantic every day？

W: I've no idea. Hundreds, I suppose.

M: And how often do you hear of a crash？ Once or twice a year？

W: Yes, but aero-planes fly so high and fast that once is enough.

M: There are more road accidents per day than air deaths per year. Air transport is really safe compared with road transport.

W: I still prefer to go by sea. Ships may not travel fast but as least you can relax. I'd love a trip on a luxury liner like the Queen Elizabeth II.

M: It's fine if you're a good sailor, but have you ever traveled far in a rough sea？

W: No. I've only been in a boat once. I sailed down the River Thames on a sightseeing tour, but in any case I'd rather be sea-sick than dead.

What is the woman afraid of when she takes her trips？

A. Taking a voyage.

B. Taking a train.

C. Taking a flight.
