We seek to classify the full-rank left-invariant control affine systems evolving on solvable three-dimensional Lie groups. In this paper we consider only the cases corresponding to the solvable Lie algebras of types II, IV , and V in the Bianchi-Behr classification.
We construct the concrete category LiCS of left-invariant control systems (on Lie groups) and point out some very basic properties. Mor-phisms in this category are examined briefly. Also, covering control systems are introduced and organized into a (comma) category associated with LiCS.

No case of concurrent interstitial ectopic pregnancy and appendicitis has ever been reported.
