Without the actual picture and graph to refer to, I can provide general advice on how to analyze such a graph.

To assess which statements could be true, you should look at the slopes of the sections in the graph:

  • A steep negative slope would indicate the car moving at a fast reverse speed.
  • A steep positive slope would indicate fast forward speed.
  • A flat horizontal line indicates the car is stationary.
  • A gentle positive slope indicates the car is moving forward but at a slower speed.

Based on this analysis, you would choose:

  • Section P for a fast reverse speed (if it shows a steep negative slope).
  • Section O for fastest forward speed (if it shows the steepest positive slope).
  • Section N for constant forward speed (if it shows a straight line with a positive slope).
  • Section M for slowest forward speed (if it shows a gentle positive slope).
  • Section N being stationary if it shows a flat line.

Given this analysis, the two statements that could potentially be true are likely to be those regarding Section O and Section N or M, depending on slopes. Carefully consider how the sections appear based on the slopes described when you have the specific graph in front of you.
