This activity has two parts.
First, create an approval process that creates more than one approval with a loop. Clone the current service item, and replace the task tree with a new tree.
You can hard-code the values for the loop, but try adding a lookup node in the loop to bring back multiple distinct values.
Second, create a variety of branches that are then brought together by a join node. Try out the different settings and see what the task management console shows.
