Good advice from Nat. A variation is to grab a colored horizontal line from an image site, or create one of your own - as a PNG file.
The background image is track one.
This initial line will be track 2 Use the POSITION effect to move it to the desired location.
Track 3 and 4 will be the second and third positions for the line, respectively.
Now ADD SIMPLE TEXT files, which will be positioned over the lines in the same fashion. These will show up on the timeline as tracks 5, 6 and 7.
Not only the line, but text too can be animated. Slide out can be plotted, or the text can be left static. Transparency can be applied to each line. Presets, like FADE OUT, can be tweaked for the text.

Yet another approach might be to place the background on track one.
Click the HOME menu item, then ADD OBJECTS|ADD ANIMATED TITLES|ADD HORIZONTAL LINE.
Size, color and position the line. Set start and end points or, If a slide out is to be programmed, animate start/end points with the POSITION EFFECT. This is track two.
Then ADD SIMPLE TEXT. Or, perhaps, ADD OBJECTS|ADD ANIMATED TITLES and choose TYPEWRITER. Use the POSITION effect to place the text on the line. That's track 3.
Follow the same procedure for additional lines, changing only the vertical offset.
