The airbag of the raft is made of     1     whole sheepskin and goes through many processes including heating to remove hair, soaking in salty oil, sewing, drying     2     blowing. Then the airbags     3     (fasten) to a wooden stand, enabling its use for transporting people and goods across the water.

The Park Hyalt Ningbo drew us to visit this city in China that we may otherwise have not yet discovered. We planned to book a First Class ticket to Ningbo but when     1     tickets for that cabin were sold out, we chose Business Class. We had no knowledge about     2     the train cabins and seats would look like, so we were more than     3     (pleasant) surprised to see that as we boarded the train. Inside, the spacious leather seats     4     (surround) by a hard shell which gives a small feeling of     5     (private).

We enjoyed traveling the CRH in Business so much     6     we decided to book the same class ticket     7     our trip back to Shanghai on our return. This time however when we boarded the train there was a small automatic door to our left and the cabin had only 9 Business Class seats. This     8     (small) cabin felt much more private. The ride was smooth and peaceful. There was also a train attendant     9     came around with water, juice and a light snack. It was great to have so much space for our luggage as well.

This is one of those cases where it really made sense for us to spend a little bit more for a far better experience.

If we find ourselves     10     (board) a CRH train again in the future, I would choose the Business Class ticket again.
