For example, suppose to visit many national parks within a time period of two weeks. For this, it is needed to gather some data about national parks and then calculate the distance between them to figure out the travel time. Next, it is required to estimate the time required to visit each park. Finally, all data must be put together to plan the trip to national parks. Then only model and camp reservations wouls be made and any other arrangements can be done. Thus, top-down design approach is followed.
Hence, the statement is.
