Suppose you want to store line segments in an R-tree. If a line segment is not parallel to the axes, the bounding box for it can be large, containing a large empty area.

Describe the effect on performance of having large bounding boxes on queries that ask for line segments intersecting a given region.

Briefly describe a technique to improve performance for such queries and give an example of its benefit. Hint: You can divide segments into smaller pieces.

Suppose that in Sherwood Forest, the average radius of a tree is R= 1 m and the average number of trees per unit area is 0.005m^(?2). If Robin Hood shoots an arrow in a randomdirection, how far, on average, will it travel before itstrikes a tree? teacher's hint: for any distance, how many trees on average will the arrow have hit? then for what distance, the number of the tree=1?
