It's quite difficult to fill the gaps without any options or choises. Accordng to the structure of the sentence, the first fap shoud be filled with adjective that emphasizes the strong motivation. And in the second gap there must be something synonymous with ''approval''. Hope it will help. Next time check it carefully.
However I am leaning towards G because it is comparing it to how a bird flies and lands near a person. Showing it travelled like a bird and using animal traits to describe it
