To "sacrifice" means to give up something for the sake of something else. We decided to sacrifice our luxurious city life to move to a seaside village with our children aged 9 and 3. In the city, we had a beautiful home and plenty of money but little real security because crime was on the increase every day. We never knew if we would all make it home safely each night.
We were very happy in the new town but life was very difficult economically. Our income was very much dependent on tourism and the jobs at other times are few. Although many of the long-standing residents live well, it is a very competitive environment for newcomers.
Reading the newspapers from big cities assured us that we had made the right choice. There is so much violence and crime there! However, it was not always easy to explain to the children why they could no longer have what they used to have, especially when our "rich" friends came from the city to visit us. Generally,
A. They were tired of city life.
B. The city was not safe enough.
C. The people in the city were not friendly.
D. The cost of living in the city was too high.
