Answer the following question: I'm taking a test and have to guess the right answer to the question after the article. Article: Many families take their children on vacation.

His sister, 9-year-old Kara, discovered that she liked Thai food. Ms. Rivenbark says that the extended trip teaches the children a lot more than short visits would have. "I think that the longer we travel, the more impact it has on how they see the world. I can see them changing more than they can see themselves." It took the family a year to prepare for the trip. They had to sell their house and cars. Ms. Rivenbark quit her job and her husband is using unpaid leave. They carry small bags filled with lightweight clothing and whatever else they need. Ms. Rivenbark says she enjoys being able to carry everything she needs on her back. She says she does not miss... Question: During the travel, _ impressed the kids as well as the parents most.
