Sprang is to leave something/someone with a quick movement and strand is to leave Some one/something with out leaving your desired spot like if you were to break up with someone you left them by their self "stranded"
Scare is something that there is not a lot of that, like if you say scarce of food this mean that there is not much food, so if you save a scarce you are saving something that there is not a lot of it.
hope I help
