Hi, I've been trying to understand the meaning of "realistic purpose" in this sentence but I can't get the meaning. I've looked for realistic and for purpose separatedly but it doesn't make sense. I'll give you the sentence: "The Crown prosecutor considers whether there's sufficient evidence to provide a realistic purpose of conviction." could enyone explain it please? I've tried to give you my options but none make sense (even for me)... THANKS! and please, correct any mistake you find!!!
