Answer 1

"The research assignment came with explicit instructions on source citation."

"Explicit" means clearly and directly stated (ex- "out" + plicit "folded" → folded out / made clear). The other sentences misuse the word (they describe situations that would call for "implicit" or contradict being explicit).
