1•The route of Abraham from Ur to Harran and Canaan. 2• The route of Abraham to Egypt and back. 3•The route of Jacob to Harran and back. 4• The route of the Israelites from Egypt to canaan. The 1st and 3rd routes crosse dover the physical feature know as the "syrian desert" Now all you have to do is follow the directions and color the trade routes in *point out that route 1 and 3 crossed the syrian desert* and your done :) Hope this helped.
