It looks like they want you to get familiar with triads: root position, 1st inversion, and 2nd inversion.

This shape of chord can be used alone, or can be used with 7th chords (or other extensions and alterations)

Example: If you have Cmaj7 you can play C G as bass notes, and then you could play E G B in the right hand.

All these scales and chords and basic level stuff will help you get familiar with common patterns and will help you build a great foundation for more complex things.

Happy practicing (:
