Based on the descriptions of the student's journey, the following statements seem to best describe the scenario:
-
The student left and came back home twice on this journey. - This indicates that there were two distinct trips away from home and two returns, which is a common pattern in a journey.
-
The student rested 3 times during his journey. - If the graph shows fluctuations in distance from home, it may indicate periods of resting or pauses in movement.
The other statements imply continual movement away from home or specific activities (e.g., searching for a dog or climbing hills) that may not be supported by the information in the graph.
