A Question about the Survey Results

In the survey that we did for class, one question asked whether we thought that some occurrences happen because of the super-natural. Another question asked whether we thought that everything came from naturalistic causes. I thought it was interesting how people answered these two questions differently because thirteen people said that everything is a cause of nature, but only seven people in the class said that there are no super-natural explanations. I thought that the questions were asking about the same concept, but maybe people are seeing a bigger idea behind them than I am. Does anyone have any thoughts on how these two questions are different and why people would answer them differently?
