Directions (66–85): record your answers in the spaces provided in your answer booklet. some questions
may require the use of the 2011 edition reference tables for physical setting/earth science
base your answers to questions 66 through 69 on the graph below and on your knowledge of earth science.
the graph shows changes in hours of daylight during the year at the latitudes of 0°, 30° n, 50° n and 60° n.

the graph in your answer booklet shows a curve for the changing length of daylight over the course of one year that occurs for an observer at 50° n latitude. on this same graph in your answer booklet, draw a line to show the changing length of daylight over the course of one year that occurs for an observer at 50° s latitude.

After doing a lot of research and looking at the graph above, I did this on paper and have got the answer for you. However, since I can't draw iny our book myself, I am going to explain where you can draw a line to show the changing length of daylight over the course of one year that occurs for an observer at 50° S latitude. 

You will need to have a line that extends from the beginning of January to the end of December. the line needs to be marked anywhere from the graph line 16 that goes downward to line 12, 8, then curves upward towards line 12 and ends at line 16 on the other side of the graph. If you need more help or don't understand, I can try to get you a picture uploaded. It isn't letting me at this time for some reason, I keep getting an error.
