Unquestioningly means accepting or doing something without asking questions, doubts, or hesitations. When you follow instructions unquestioningly, you trust them completely and don't stop to wonder if they might be wrong.

Sometimes following unquestioningly makes sense. A firefighter responding to an emergency follows their training unquestioningly because there's no time to debate each step. A young child might obey their parent unquestioningly when told to stop at the curb before crossing the street.

But accepting everything unquestioningly can lead to problems. Scientists don't accept theories unquestioningly: they test, question, and verify. Good students don't just memorize facts unquestioningly: they ask why things work the way they do. That curiosity and skepticism often lead to better understanding and new discoveries.

Notice how unquestioningly differs from trustingly: trust involves confidence based on experience or relationship, while following unquestioningly means not even pausing to think about whether something makes sense.
