Answer:
Option 1, 2, 5
Explanation:
Options for the question 
- car a and car b are both moving toward the origin.
- car a and car b are moving in opposite directions.
- car a is moving faster than car b.
- car a and car b started at the same location.
- car a and car b pass each other at the crossover  point on the graph.  time (s)
Solution - 
The motion of any object is represented by  position-time In such graphs the position of an object is fixed for any starting point on the y-axis and time on the x-axis. 
The slope of such curves determine the velocity of the object at all its position within the graph. The steeper the slope is, the faster the the object is moving.
Hence, the following statements are correct
Option 1, 2, 5

Also, only planting one crop in an area can change the pH and nitrogen levels in negative ways, so that eventually no plants can grow there. Not to mention the obvious balanced diet needed for a healthy body.
