Understanding motion from a position-time graph

An object's motion is described by the position-time graph below.

1. Select all regions where the object's velocity is primarily positive.

Select all possible options that apply.

2. At point E, the object's acceleration is:

3. At point F, the object is:

4. What is the average velocity of the object during the time interval from $t = 0\rm\ s$ to $t = 5\rm\ s$?

$v_{\rm avg} = $ $\rm\ m/s$

5. How do the velocities of the object at points B and C compare?
