Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions.

       It is a characteristic of human nature that people like to get together and have fun, and people live during America's frontier days were no exception. However, because life was hard and the necessities of day-to-day living took up their time, it was common for recreation to be combined with activities necessary for survival. One example of such a form of recreation was logrolling. Many frontier areas were heavily wooded, and in order to settle an area it was necessary to move the trees. A settler could cut down the trees alone, but help was needed to move the cut trees. After a settler had cut a bunch of trees, he would then invite is neighbours over for a logrolling. A logrolling is a community event where families got together for a combination of work and fun. The women would bring food and have a much needed and infrequent opportunity to relax and chat with friends, the children would play together exuberantly, and the men would hold lively competitions that involved rolling logs from place to place as quickly as possible. This was a day of fun for everyone involved, but as its foundation was the need to clear the land.

According to the passage, what did people have to do first to settle an area?
